Silva FG, Silva SR, Pereira AMF, Cerqueira JL, Conceição C. A Comprehensive Review of Bovine Colostrum Components and Selected Aspects Regarding Their Impact on Neonatal Calf Physiology. Animals (Basel) 2024; 14:1130. [PMID: 38612369 PMCID: PMC11010951 DOI: 10.3390/ani14071130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 04/04/2024] [Accepted: 04/05/2024] [Indexed: 04/14/2024] Open
Abstract
Colostrum contains macro- and micronutrients necessary to meet the nutritional and energy requirements of the neonatal calf, bioactive components that intervene in several physiological aspects, and cells and microorganisms that modulate the calf's immune system and gut microbiome. Colostrum is sometimes mistaken as transition milk, which, although more nutritive than whole milk, has a distinct biochemical composition. Furthermore, most research about colostrum quality and colostrum management focuses on the transfer of maternal IgG to the newborn calf. The remaining components of colostrum and transition milk have not received the same attention, despite their importance to the newborn animal. In this narrative review, a large body of literature on the components of bovine colostrum was reviewed. The variability of these components was summarized, emphasizing specific components that warrant deeper exploration. In addition, the effects of each component present in colostrum and transition milk on several key physiological aspects of the newborn calf are discussed.

Dietary L-Carnitine Affects Leukocyte Count and Function in Dairy Cows Around Parturition. Front Immunol 2022; 13:784046.

Abstract
In early lactation, an energy deficit leading to a negative energy balance (NEB) is associated with increased susceptibility to disease and has been shown to be an important factor during transition in dairy cows. L-carnitine as a key factor in the mitochondrial transport of fatty acids and subsequently for β-oxidation and energy release is known to modulate mitochondrial biogenesis and thus influence metabolism and immune system. In the current study, we characterized hematological changes around parturition and investigated the potential effects of dietary L-carnitine supplementation on immune cell functions. For this approach, dairy cows were assigned either to a control (CON, n = 30) or an L-carnitine group [CAR, n = 29, 25 g rumen-protected L-carnitine per cow and day (d)]. Blood samples were taken from d 42 ante partum (ap) until d 110 post-partum (pp), with special focus and frequent sampling from 0.5 to72 h post-calving to clarify the impact of L-carnitine supplementation on leukocyte count, formation of reactive oxygen species (ROS) in polymorphonuclear cells (PMN) and peripheral mononuclear cells (PBMC) and their phagocytosis activity. Blood cortisol concentration and the capacity of PBMC proliferation was also investigated. All populations of leukocytes were changed during the peripartal period, especially granulocytes showed a characteristic increase up to 4 h pp. L-carnitine supplementation resulted in increased levels of eosinophils which was particularly pronounced one day before to 4 h pp, indicating a possible enhanced support for tissue repair and recovery. Non-supplemented cows showed a higher phagocytic activity in PBMC as well as a higher phagocytic capacity of PMN during the most demanding period around parturition, which may relate to a decrease in plasma levels of non-esterified fatty acids reported previously. L-carnitine, on the other hand, led to an increased efficiency to form ROS in stimulated PMN. Finally, a short period around calving proved to be a sensitive period in which L-carnitine administration was effective.

Abstract
Interleukin 8 (IL8) is a major mediator of the innate immune response. Polymorphisms in this gene are associated with susceptibility to inflammatory disease in humans. Two major promoter polymorphic haplotypes (IL8-h1 and IL8-h2) segregating in cattle populations have shown a significant effect on the immune response profile in calves but their implications for transition cow immunity have not been established. The aims of this study were to assess functional relevance of the IL8 haplotypes on the immunological traits of periparturient cows (n = 32) belonging to three genetic groups: Holstein (HO), Simmental (SI) and their crosses (CR) and to evaluate the frequency of IL8 haplotypes in the HO (dairy) and SI (dual purpose) pure breeds. IL8 haplotypes showed a significant effect on circulating number of both T helper lymphocytes (P = 0.0133) and T cytotoxic lymphocytes (P = 0.0024). Differences in percentage of CD14+ monocytes and T lymphocyte subsets were found between haplotype groups at different time points. Plasma concentrations of Serum Amyloid A (SAA) and Haptoglobin (Hp) were enhanced at calving in IL8-h2 (P = 0.0019, P = 0.0029) and IL8-het (P = 0.050 and P = 0.052) respectively, compared with IL8-h1 cows. In contrast, significantly lower levels of reactive oxygen metabolites (d-ROMs) activation were identified in IL8-h2 and IL8-het cows after calving compared with IL8-h1 cows. Furthermore, genotyping results showed that SI cows have a high frequency of the homozygous IL8-h2 haplotype compared to the HO cows (87.5 % vs 40 %) which reflects the different selective pressure between the two pure breeds. In conclusion, our preliminary data suggests that IL8 promoter haplotype is associated with significant and dynamic changes in immunological traits during peripartum and early lactation period. Future work will focus on a more comprehensive assessment of immune changes in additional cows.

Abstract
AbstractThe experiment described in this research communication aimed to compare the immunological traits of Simmental (sire) × Holstein (dam) crossbred cows with the two parental breeds in the peripartum and early lactation period and to estimate the effects of heterosis for these traits. Flow cytometric evaluation of leukocyte subpopulations was assessed in 16 Crossbred (CR), 8 Holstein (HO) and 8 Simmental (SI) cows. Estimated average values of innate and adaptive immune cells showed statistically significant differences between the crossbred cows and parental breeds. Interestingly, the most relevant differences between the three groups related to adaptive immune cells. In particular, the CR cows showed a lower percentage of CD3+ T lymphocytes compared with the SI group (P < 0.0001) and the highest proportions of CD21+ B lymphocytes among the three groups (P < 0.0001). Furthermore, we found the highest positive value of heterosis for the CD21+ B lymphocytes (7.0) and the lowest negative value for CD3+ T lymphocytes (−4.8) in F1 derived population. It seems reasonable to believe that these differences could affect immune function of crossbred cows.

Abstract
Immune cell functions such as phagocytosis and synthesis of immunometabolites, as well as immune cell survival, proliferation and differentiation, largely depend on an adequate availability of glucose by immune cells. During inflammation, the glucose demands of the immune system may increase to amounts similar to those required for high milk yields. Similar metabolic pathways are involved in the adaptation to both lactation and inflammation, including changes in the somatotropic axis and glucocorticoid response, as well as adipokine and cytokine release. They affect (i) cell growth, proliferation and activation, which determines the metabolic activity and thus the glucose demand of the respective cells; (ii) the overall availability of glucose through intake, mobilization and gluconeogenesis; and (iii) glucose uptake and utilization by different tissues. Metabolic adaptation to inflammation and milk synthesis is interconnected. An increased demand of one life function has an impact on the supply and utilization of glucose by competing life functions, including glucose receptor expression, blood flow and oxidation characteristics. In cows with high genetic merits for milk production, changes in the somatotropic axis affecting carbohydrate and lipid metabolism as well as immune functions are profound. The ability to cut down milk synthesis during periods when whole-body demand exceeds the supply is limited. Excessive mobilization and allocation of glucose to the mammary gland are likely to contribute considerably to peripartal immune dysfunction.

Abstract
In dairy cows, retained fetal membranes (RFM) affect reproductive performance. The aim of this study was to examine the leukocyte counts and the gene expression of tumour necrosis factor α (TNFα), interleukin 1β (IL-1β), IL-8, and IL-10 in polymorphonuclear leukocytes (PMNs) and peripheral blood mononuclear cells (PBMCs) in cows with (n = 5) or without (n = 5) RFM during the peripartum period. The lymphocyte counts in RFM cows were higher than those in control cows throughout the experiment (p < .05). The expression of IL-8 in PMNs of control cows was higher (p < .05) compared with that of RFM cows postpartum. In cows with RFM, IL-1β expression was higher (p < .05) in PMNs at 6 weeks postpartum whereas the expression of IL-1β was lower (p < .05) in PBMCs at 4 weeks postpartum. The expression of IL-10 in PBMCs of control cows was higher (p < .05) than that of RFM cows at 2 weeks prepartum and 4 weeks postpartum. Taken together, our data indicate that changes of gene expression of pro- and anti-inflammatory cytokines in RFM cows might be associated with the delayed placental separation and development of uterine inflammation in RFM cows.

Type I and type II cytokine production of CD4+ T-cells in immune response biased dairy cattle around calving. Vet Immunol Immunopathol 2018; 199:70-76.

Abstract
The peripartum period is a period of high stress, transition and management changes for dairy cows. It is associated with higher incidence of both metabolic and pathogenic disease. Both antibody-(AMIR) and cell-(CMIR) mediated immune responses play a key role in the maintenance of health in mammals protecting against extracellular and intracellular pathogens, respectively. Generally, interferon gamma (IFN-γ) has been associated with CMIR, whereas interleukin 4 (IL-4) has been associated with AMIR bias, and interleukin 17 (IL-17A) is associated with pro-inflammatory. It has been previously demonstrated that cows can be classified as high (H), average (A), and low (L) immune responders based upon their AMIR and CMIR to test antigens, and that this classification is associated with disease occurrence throughout lactation. The mechanisms behind these differences in phenotype and the effects of the peripartum period have not been fully investigated. The aim of this study was to determine the effects of the peripartum period on cytokine production of CD4+ T-cells or T helper (Th) cells, key mediators of the adaptive immune response. Immune response phenotyped cows were selected based on H-AMIR/L-CMIR (H-AMIR cows; n = 10) and H-CMIR/L-AMIR (H-CMIR cows; n = 11) response to test antigens. Isolated CD4+ T-cells collected at 28 days before calving (prepartum samples), 4 days after calving (early postpartum samples), and 21 days after calving (late postpartum samples) from these groups were stimulated with Concanavalin-A (ConA) with unstimulated controls. Subsequently, IL-4, IFN-γ, and IL-17A concentrations were quantified by ELISA. Overall, there was no obvious decline in IL-4, IFN-γ or IL-17A close to calving observed from CD4+ T-cells from each of these phenotypically distinct groups of cows. However, CD4+ T-cells isolated from H-CMIR secreted higher amounts of IL-4 (746.43 ± 428 pg/mL), IL-17A (446IL ± 62 pg/mL), and IFN-γ (7755.79 ± 4449 pg/mL) than H-AMIR cows (IL-4 (212.15 ± 121 pg/mL), IL-17A (163.15 ± 87 pg/mL), and IFN-γ (2909.771 ± 1671 pg/mL)) on day 21 after calving, late postpartum. This study indicates a genetic predisposition based on immune response phenotype of cytokine production from CD4+ T-cells around calving.

Abstract
RESUMO Esta pesquisa avaliou a dinâmica dos leucócitos e das subpopulações de linfócitos em vacas Holandesas soropositivas para o BLV no período de transição. Amostras de sangue (n=72) provenientes de 12 vacas foram coletadas entre as semanas -2 e +3 para a realização do leucograma, imunofenotipagem, dosagem de cortisol e haptoglobina (Hp). O perfil leucocitário foi caracterizado por leucocitose, neutrofilia, monocitose e eosinopenia próximo ao parto. Linfocitose e elevada proporção de linfócitos B CD21+ foram achados constantes entre as semanas -2 e +3; assim, as vacas foram testadas e confirmadas soropositivas para o BLV. Os valores das subpopulações de linfócitos T apresentaram-se baixos durante o período de transição, observando-se dois picos máximos que coincidiram com as elevações nas concentrações de cortisol no parto (2,11µg/dL) e semana +3 (1,97µg/dL). Hp apresentou aumento crescente de -2 (166µg/mL) a +3 (576µg/mL), provavelmente associada à elevada taxa de infecções uterinas observadas nas semanas +2 e +3. As vacas soropositivas para o BLV apresentaram leucograma de estresse próximo ao parto, exceto para linfócitos. A linfocitose e as elevadas proporções de células B CD21+, associadas com as baixas proporções de células T, podem ser indicativo de imunossupressão e predisposição aos processos inflamatórios no período pós-parto.

Abstract
Using a model to generate experimental groups with different manifestations of post-partum (p.p.) fat mobilization and ketogenesis, the effects of a dietary and a medical intervention on biochemical and haematological parameters, antibody titre, leucocytes subsets and function of transition cows were examined. In total, 60 German Holstein cows were allocated 6 weeks antepartum (a.p.) to 3 high-body condition score (BCS) groups (BCS 3.95) and 1 low-BCS group (LC, BCS 2.77). High-BCS cows received a monensin controlled-release capsule (HC/MO) or a blend of essential oils (HC/EO) or formed a control group (HC). Parameters were evaluated in 3 periods (day (d) -42 until calving, 1 until 14 days in milk (DIM), 15 until 56 DIM). Over the course of trial, various parameters were influenced by period with greatest variability next to calving. White blood cell count was higher in the HC (8.42 × 103 /μl) and HC/EO (8.38 × 103 /μl) groups than in the HC/MO group (6.81 × 103 /μl) considering the whole trial. Supplementation of monensin decreased aspartate aminotransferase in comparison with the HC group similar to LC treatment. Bilirubin concentration was nearly doubled in all high-BCS cows in period 2. In period 3, essential oils increased γ-glutamyltransferase (80.4 Units/l) in comparison with all other groups and glutamine dehydrogenase (61 Units/l) in comparison with the LC (19 Units/l) and the HC/MO group (18 Units/l). Results suggest that parameters were generally characterized by a high variability around calving. Based on biochemical characteristics, it appeared that the HC cows seemed to have compromised hepatocyte integrity when compared to the LC cows. From the immune parameters investigated, the BVDV antibody response was more pronounced in HC/MO compared to HC/EO.

[PMID: 26479393 PMCID: PMC4598713 DOI: 10.3390/ani5030391] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2015] [Revised: 08/13/2015] [Accepted: 08/31/2015] [Indexed: 01/29/2023] Open
Abstract
Simple Summary Several biological changes occur during the transition from late pregnancy to early lactation which is associated with a high susceptibility of health disorders. Nicotinic acid, as feed additive, is suggested to balance catabolic metabolism of periparturient dairy cows by attenuating lipolysis and impact production performance. This study provides information of the biological changes occurring around parturition with special emphasis on differences between primiparous and multiparous cows. Present results showed that energy-dense feeding prepartum did not result in metabolic imbalances postpartum in dairy cows which were similar in body condition score. Nicotinic acid supplementation did not reveal any effect. Abstract The periparturient period is critical according to health, productivity and profitability. As this period is fundamental for the success of the lactation period, the interest in improving periparturient health by dietary supplements increased in recent years. The present study investigated the effects of feeding nicotinic acid (NA) combined with varying dietary energy densities on immunological, hematological and biochemical parameters of periparturient cows differing in parity. Thirty-six multiparous and 20 primiparous dairy cows were enrolled in the study 42 days before expected parturition date until 100 days postpartum with the half of the cows being supplemented with 24 g of NA/d. After parturition a diet with 30% concentrate was fed to all cows which was followed by different concentrate escalation strategies. Dietary NA supplementation was ceased on day 24 postpartum. Dietary NA increased (P = 0.010) serum nicotinamide concentrations (mean of 3.35 ± 1.65 µg/mL), whereas NA could not be detected. Present data emphasize that periparturient cows are faced with major physiological challenges and that both parity-groups have different prerequisites to adapt to those changes irrespective of NA supplementation. The overfeeding of energy to cows which were similar in body condition score had only minor effects on periparturient immune system function and the metabolism of those cows.

Abstract
Pregnant heifers in the feedlot pose many economic and management issues to the producer. Heifers that enter the feedlot pregnant will have increased costs associated with them regardless of the management strategy implemented. It is imperative that practitioners be aware of management concerns associated with pregnant heifers in order to provide sound recommendations for their clients. The purpose of this article is to provide the bovine practitioner with a summary of current literature and present common options for managing pregnant heifers in a feedlot setting.

Abstract
Background Acute puerperal metritis (APM) affects 30% of postpartum dairy cattle. Bacteremia negatively impacts survival in cattle with coliform mastitis. However, the prevalence of bacteremia in dairy cattle with APM is unknown. Hypothesis Bacteremia is detectable in a large proportion of cattle with APM. Animals Seventeen dairy cows with APM and 17 healthy dairy cattle. Methods Prospective case‐control study. Cases were identified by daily monitoring of cattle in the first 10 days after calving. Controls were matched to cases by parity and days in milk. Cows were examined at the time of identification of APM. A complete blood count, serum biochemical analysis, and bacteriologic culture of blood and lochial fluid were performed on each animal at the time of diagnosis. The same samples were collected from healthy herdmates of a similar parity and days in milk. Blood culture results and clinicopathologic variables were compared between groups. Conditional logistic regression was used to evaluate factors associated with APM, whereas multivariate logistic regression was used to evaluate factors associated with bacteremia. Results Bacteremia occurred in 53% (9/17) of cattle with APM and 53% (8/15) controls. Bacillus spp. was the organism most commonly isolated from the bloodstream in cattle of both groups. Bacteremic cattle in both groups were significantly less likely to have basophils in the peripheral circulation (P = .02) and more likely to have higher serum globulin concentrations (P = .02). Conclusions and Clinical Importance Bacteremia is a common occurrence in postpartum dairy cattle. Further study is warranted to investigate the modes by which bacteria colonize the bloodstream in this population of animals and the importance of bacteremia on health and productivity of affected animals.

Abstract
Despite Neospora caninum being a major cause of bovine abortion worldwide, its pathogenesis is not completely understood. Neospora infection stimulates host cell-mediated immune responses, which may be responsible for the placental damage leading to abortion. The aim of the current study was to characterize the placental immune response following an experimental inoculation of pregnant cattle with N. caninum tachyzoites at day 210 of gestation. Cows were culled at 14, 28, 42 and 56 days post inoculation (dpi). Placentomes were examined by immunohistochemistry using antibodies against macrophages, T-cell subsets (CD4, CD8 and γδ), NK cells and B cells. Macrophages were detected mainly at 14 days post inoculation. Inflammation was generally mild and mainly characterized by CD3+, CD4+ and γδ T-cells; whereas CD8+ and NK cells were less numerous. The immune cell repertoire observed in this study was similar to those seen in pregnant cattle challenged with N. caninum at early gestation. However, cellular infiltrates were less severe than those seen during first trimester Neospora infections. This may explain the milder clinical outcome observed when animals are infected late in gestation.

Abstract
There is a molecular crosstalk between the trophoblast and maternal immune cells of bovine endometrium. The uterine cells are able to secrete cytokine/chemokines to either induce a suppressive environment for establishment of the pregnancy or to recruit immune cells to the endometrium to fight infections. Despite morphological differences between women and cows, mechanisms for immune tolerance during pregnancy seem to be conserved. Mechanisms for uterine immunesuppression in the cow include: reduced expression of major histocompatability proteins by the trophoblast; recruitment of macrophages to the pregnant endometrium; and modulation of immune-related genes in response to the presence of the conceptus. Recently, an eGFP transgenic cloned embryo model developed by our group showed that there is modulation of foetal proteins expressed at the site of syncytium formation, suggesting that foetal cell can regulate not only by the secretion of specific factors such as interferon-tau, but also by regulating their own protein expression to avoid excessive maternal recognition by the local immune system. Furthermore, foetal DNA can be detected in the maternal circulation; this may reflect the occurrence of an invasion of trophoblast cells and/or their fragment beyond the uterine basement membrane in the cow. In fact, the newly description of exosome release by the trophoblast cell suggests that could be a new fashion of maternal-foetal communication at the placental barrier. Additionally, recent global transcriptome studies on bovine endometrium suggested that the immune system is aware, from an immunological point of view, of the presence of the foetus in the cow during early pregnancy.

Abstract
The purpose of this study was to identify the influence of physiological state, season, breed, number of lactations, dairy productivity, and stocking rate on infestation by Rhipicephalus microplus in dairy cows. Two hundred cows were selected through proportional representative sampling at the Seropédica Experimental Station (Pesagro-Rio), Brazil. Fully or partially engorged R. microplus females measuring between 4.5 and 8.0mm were counted on the right side of each animal. The tick infestation prevalence data were analyzed in relation to the risk factors, using multiple logistic regression. Associations between prevalence and its possible influencing determinants were measured using odds ratios. The average tick count of cows during the peripartum and lactation periods was significantly higher (p<0.05; OR=4.82) than the count in dry cows. Taurine animals showed significantly higher infestation (p<0.05; OR=3.28) than pure zebuine animals. Among cross-bred animals, the infestation was higher (p<0.05) in F1 animals (1/2 taurine×1/2 zebuine) than in Girolando animals (5/8 zebuine×3/8 taurine). Primiparous cows (p<0.05) had significantly heavier infestations than multiparous cows. Dairy production showed a positive correlation with tick infestation (p<0.03; OR=2.94), such that the most productive animals were the most parasitized ones. Animals kept at high densities were significantly more heavily infested (p<0.05, OR=6.32) than animals kept at low density. First-lactation and high-productivity taurine animals were more vulnerable to R. microplus, thus comprising a high-risk group in dairy herds.

The effect of dexamethasone on clock gene mRNA levels in bovine neutrophils and lymphocytes. Vet Immunol Immunopathol 2010; 138:183-92.

Abstract
Circadian rhythms are driven by oscillating expression of a family of transcription factors called clock genes. In rodents, clock genes drive circadian rhythms in white blood cell function, and glucocorticoids are believed to regulate these rhythms. Little is known about circadian rhythms of cattle white blood cells. The objectives of this study were: (1) to quantify mRNA levels of clock genes in neutrophils and lymphocytes over 24h in healthy steers; and (2) to quantify effects of dexamethasone on clock gene mRNA levels in bovine neutrophils and lymphocytes. We hypothesized that bovine neutrophils and lymphocytes would display 24h variations in clock gene mRNA levels and that those patterns would be disrupted by glucocorticoid treatment. Six Holstein steers were injected with 0 or 0.10mg/kg body weight dexamethasone according to a crossover design. Neutrophils and lymphocytes were collected from jugular blood at 0, 4, 8, 12, 16, 20, and 24h relative to treatment administration. Neutrophil and lymphocyte mRNA levels of the clock genes Clock, Bmal1, Per1, Per2, Cry1, Cry2, Rev-erbα, and CK1ɛ were quantified. For neutrophils, an interaction between treatment and time was found for Clock, Cry1, and CK1ɛ. Time affected Clock, Per1, Cry1, Rev-erbα, and CK1ɛ. For all of those genes except Per1, neutrophils from control steers displayed 24h changes of mRNA levels characteristic of circadian regulated cells. The dexamethasone treatment increased neutrophil mRNA levels of Per1, decreased Clock, Cry1, Cry2, and Rev-erbα, and tended to decrease Bmal1. These results suggest that circadian rhythms have the potential to impact bovine neutrophil function, and that glucocorticoid-induced disruption of neutrophil circadian rhythms may contribute to periparturient immunosuppression. For lymphocytes, an interaction between treatment and time was observed for Per1 and tended to occur for Per2 and Cry2. Although time affected Per1 and Rev-erbα, distinct 24h patterns of lymphocyte clock gene mRNA levels were not evident as they were in neutrophils. Treatment increased Per1 and decreased Cry2, but the magnitude of the treatment effect was small. In summary, 24h patterns in clock gene mRNA levels were observed in bovine neutrophils and to some degree in lymphocytes, and these patterns were disrupted by dexamethasone administration. Although further research is needed, individual variation in white blood cell circadian rhythms and glucocorticoid responsiveness may help to explain individual differences in periparturient disease susceptibility.

Abstract
BACKGROUND Sixteen, spring-born, single suckled, castrated male calves of Limousin x Holstein-Friesian and Simmental x Holstein-Friesian dams respectively, were used to investigate the effect of weaning on total leukocyte and differential counts, neutrophil functional activity, lymphocyte immunophenotypes, and acute phase protein response. Calves grazed with their dams until the end of the grazing season when they were housed in a slatted floor shed. On the day of housing, calves were assigned to a treatment, (i) abruptly weaned (W: n = 8) or (ii) non-weaned (controls) (C: n = 8). Weaned calves were housed in pens without their dams, whereas non-weaned (control) calves were housed with their dams. Blood was collected on day -7, 0 (housing), 2, 7, and 14 to determine total leukocyte and differential counts and concentration of fibrinogen and haptoglobin. Lymphocyte immunophenotypes were characterised using selected surface antigens (CD4+, CD8+, WC1+ (gammadelta T cells), MHC Class II+ lymphocytes), and the functional activities of neutrophils (surface expression of L-selectin (CD62L), phagocytic and oxidative burst activity) were investigated using flow cytometry. RESULTS Treatment x sampling time interactions (P < 0.05) were detected for total leukocyte and neutrophil counts, all lymphocyte subsets, mean fluorescence intensity of CD62L+ neutrophils, and percentage neutrophils performing phagocytosis. On d 2, total leukocyte and neutrophil count increased (P < 0.001), and percentage CD4+ and CD8+ lymphocytes, percentage phagocytic neutrophils, mean fluorescence intensity of CD62L+ neutrophils decreased (P < 0.05) in W compared with baseline (d 0), whereas they were unchanged (P > 0.05) in C. On d 2, percentage WC1+ lymphocytes decreased (P < 0.05), whereas percentage MHC class II+ lymphocytes increased (P < 0.05) in W and C, however the magnitude of change was greater in W than C. There were no treatment x sampling time interactions (P > 0.05) for monocyte, eosinophil, and basophil counts, percentage G1+ neutrophils, or percentage oxidative burst positive neutrophils. CONCLUSIONS Abrupt weaning resulted in increased neutrophil counts and impaired trafficking and phagocytic function. Together with the changes in lymphocyte subsets, the results suggest that there was a greater transitory reduction in immune function at housing in abruptly weaned than non-weaned beef calves.

Abstract
Increased energy demands to support lactation, coupled with lowered feed intake capacity results in negative energy balance (NEB) and is typically characterized by extensive mobilization of body energy reserves in the early postpartum dairy cow. The catabolism of stored lipid leads to an increase in the systemic concentrations of nonesterified fatty acids (NEFA) and β-hydroxy butyrate (BHB). Oxidation of NEFA in the liver result in the increased production of reactive oxygen species and the onset of oxidative stress and can lead to disruption of normal metabolism and physiology. The immune system is depressed in the peripartum period and early lactation and dairy cows are therefore more vulnerable to bacterial infections causing mastitis and or endometritis at this time. A bovine Affymetrix oligonucleotide array was used to determine global gene expression in the spleen of dairy cows in the early postpartum period. Spleen tissue was removed post mortem from five severe NEB (SNEB) and five medium NEB (MNEB) cows 15 days postpartum. SNEB increased systemic concentrations of NEFA and BHB, and white blood cell and lymphocyte numbers were decreased in SNEB animals. A total of 545 genes were altered by SNEB. Network analysis using Ingenuity Pathway Analysis revealed that SNEB was associated with NRF2-mediated oxidative stress, mitochondrial dysfunction, endoplasmic reticulum stress, natural killer cell signaling, p53 signaling, downregulation of IL-15, BCL-2, and IFN-γ; upregulation of BAX and CHOP and increased apoptosis with a potential negative impact on innate and adaptive immunity.

Abstract
The presence of conceptus alloantigens necessitates changes in maternal immune function. Here, we used the cow to evaluate whether species with epitheliochorial placentation have changes in specific leukocyte populations during pregnancy similar to those reported in species with hemotropic placentae. At days 33–34 of pregnancy, there was no effect of pregnancy status on the number of cells positive for CD8, CD4, γδT cell receptor, or the monocyte marker CD68 in the peripheral blood mononuclear cell (PBMC) population. There was, however, an increase in the proportion of CD4+cells that were positive for CD25. There was no effect of status on the proportion of PBMCs that were CD8+when comparing preparturient cows to nonpregnant cows. However, preparturient cows had an increased percentage of PBMCs that were γδT cells and CD4+CD25+and a tendency for a lower percentage that were CD68+cells. Using immunolocalization with anti-CD68, it was found that pregnant cows had increased numbers of CD68+cells in the endometrial stroma as early as days 54–100 of gestation; this increase persisted through the last time examined (day 240 of gestation). Cells positive for CD68 were also positive for another macrophage/monocyte marker, CD14. In conclusion, pregnancy in the cow is associated with changes in peripheral and endometrial leukocyte numbers, which are similar to patterns observed in other species.

Abstract
The effect of transportation on peripheral blood lymphocyte subsets in 24 calves was investigated by flow cytometry. Blood was collected before departure, on arrival, at 24h and 1 week after arrival. Highest leucocyte and neutrophil counts, associated with increased concentrations of cortisol and catecholamines, indicated that stress was maximal upon arrival. At this time, a decrease in the percentages of all T lymphocyte subsets was evident, while they did not decrease as absolute counts. The proportion of CD21(+) cells did not change, indicating that the relative reduction of T lymphocyte subsets was not related to an increase in B lymphocytes. These variations may be due to the increase of a natural killer (NK) cell subset. NK cell expansion, together with increasing lymphocyte count and increasing major histocompatibility complex class II expression, may indicate stress-induced stimulation of the immune system.

Abstract
AbstractMycobacterium aviumsubspeciesparatuberculosis(M. paratuberculosis) is the causative agent of Johne’s disease, a deadly intestinal ailment of ruminants. Johne’s disease is of tremendous economic importance to the worldwide dairy industry, causing major losses due to reduced production and early culling of animals. A highly controversial but developing link between exposure toM. paratuberculosisand human Crohn’s disease in some individuals has led to the suggestion thatM. paratuberculosisis also a potential food safety concern. As with many other mycobacteria,M. paratuberculosisis exquisitely adapted to survival in the host, despite aggressive immune reactions to these organisms. One hallmark of mycobacteria, includingM. paratuberculosis, is their propensity to infect macrophages. Inside the macrophage,M. paratuberculosisinterferes with the maturation of the phagosome by an unknown mechanism, thereby evading the host’s normal first line of defense against bacterial pathogens. The host immune system begins a series of attacks againstM. paratuberculosis-infected macrophages, including the rapid deployment of activated γδ T cells, CD4+T cells and cytolytic CD8+T cells. These cells interact with the persistently infected macrophage and with each other through a complex network of cytokines and receptors. Despite these aggressive efforts to clear the infection,M. paratuberculosispersists and the constant struggle of the immune system leads to pronounced damage to the intestinal epithelial cells. Enhancing our ability to control this important and tenacious pathogen will require a deeper understanding of howM. paratuberculosisinterferes with macrophage action, the cell types involved in the immune response, the cytokines these cells use to communicate, and the host genetic factors that control the response to infection.

Abstract
Fifteen clinically healthy calves were sampled every week during the first 5 weeks of life and thereafter every month until the age of 6 months. The percentages and absolute values of CD4+, CD8+ gammadelta TCR+ and WC1+ T cells, CD21+ B cells and NKp46+ NK cells were determined by flow cytometry, and the expression of the interleukin-2 receptor alpha chain (CD25) was measured to assess the level of activation of the lymphocyte subpopulations. Neutrophil phagocytosis, respiratory burst and bactericidal activity were measured in five different neutrophil function assays. Most of the parameters examined reached a stable level during the first 6 months of life. The proportions of CD4+ and CD8+ lymphocytes remained relatively stable during the study period, while there was a moderate decrease in the relative percentage of gammadelta T cells from birth to approximately 5 months of age. However, the absolute numbers of gammadelta T cells per millilitre of blood remained stable throughout the study period and did not display significant variation with age. The percentage of cells expressing the B-cell maturation marker CD21 increased significantly over the first 5 months of life. The proportion of NK cells showed substantial variation during the study. Marked differences in the relative proportions of the lymphocyte subpopulations were noted between the individual calves, and the individual ranking of the animals was largely maintained over time. CD25 expression was detected on a mean of 6.6% of the CD4+ cells, while a lower percentage of the other lymphocyte subpopulations expressed this receptor. Phagocytic activity was demonstrated in approximately 90% of the neutrophils, and this proportion remained stable during the entire study period, while respiratory burst activity showed a moderate decrease during the first 2 months of life. The present study shows that the T-cell subpopulations are present in peripheral blood of calves at levels comparable with adult values, while the B-cell population increases significantly with age. The decrease in the relative percentage of gammadelta T cells appears to be attributable to an increase in the absolute numbers of CD4+ and CD21+ cells, rather than a change in absolute gammadelta T-cell numbers. Furthermore, the results indicate that the neutrophilic granulocytes are functional and able to mount an effective response in young calves from the first week of life.

Abstract
Seventeen multiparous Holstein cows were used to examine the effect of an increased duodenal supply of Gln on immune function and production. Cows received continuous abomasal infusions of water (control: n = 8) or 300 g/d of Gln (n = 9) for 21 d starting within 48 h of calving. There were nonsignificant increases in milk and milk protein yields in response to Gln supplementation. Glutamine treatment had no effect on plasma glucose, nonesterified fatty acids (NEFA), or beta-hydroxybutyrate (BHBA) concentrations but did tend to increase plasma urea N concentration. The Gln treatment resulted in an increase of 108 microM in the plasma Gln concentration. Total essential AA concentrations decreased with the Gln treatment, whereas total nonessential AA concentrations were unaffected. T Lymphocyte proliferation did not differ between the control and Gln-treated cows. Treatment had no effect on the relative abundance of CD8 T cells but did increase the abundance of CD4 T cells. Cytokine production, as measured by IFN-gamma concentration determined in vitro in concanavalin-A-stimulated peripheral blood mononuclear cells, was similar between the treatments. Over the first 3 wk following calving, Gln supplementation had limited effects on milk production, metabolic parameters, and immune function.

Abstract
PROBLEM Somatic cloning technology is beneficial for genetically producing excellent animals. However, many developmental problems of somatically cloned animals have been described. Some of them may cause disorders of the immune system, resulting in the fluctuation of the proportion of white blood cells (WBC), different from that of normal animals in peripheral blood. METHOD OF STUDY In Holstein- cloned and normal cows, the fluctuation of granulocytes, monocytes, B cells and T cells, and further T cell subsets (CD4+, CD8+, gammadelta, CD8+gammadelta and WC1+gammadelta T cell) in peripheral blood were analyzed in early lactation stage (ELS) and mid to late lactation stage (MLS) by flow cytometry using specific monoclonal antibodies for cell surface markers. RESULTS In both ELS and MLS, there were no significant differences in the proportions of granulocytes, monocytes, B cells and T cells between cloned and normal cows. In T cell subsets, gammadelta and WC1+gammadelta T cells in cloned cows were significantly less frequent than in normal cows in ELS. The decreased proportions of gammadelta and WC1+gammadelta T cells recovered to the level of normal cows in MLS. CONCLUSIONS The population of granulocytes, monocytes, B cells and T cells, and T cell subsets except for gammadelta and WC1+gammadelta T cells in cloned cows fluctuated in a manner similar to those of normal cows during lactation. In ELS, the proportions of gammadelta and WC1+gammadelta T cells temporarily declined in cloned cows, suggesting that cloned cows may fall into an immunosuppressive state in ELS.

Abstract
The consequences of pregnancy and social stress on blood immune cells and on plasma corticosterone concentrations were assessed in Long Evans rats. Normal pregnancy in control females was characterized by a progressive increase in corticosterone concentration and increasing numbers of granulocytes. In contrast, CD4 T, CD8 T, and B cell numbers as well as the proliferative response of lymphocytes decreased as pregnancy progressed. Stress was induced in pregnant females by social confrontation for 2 h daily with a female resident opponent over a period of 2 months. Corticosterone concentrations were substantially higher in pregnant stressed than in pregnant control rats. Furthermore, the numbers of monocytes, NK and B cells were lower in stressed females, and there was a strong trend towards suppressed lymphocyte proliferation. Interestingly, pregnant females did not show granulocytosis in response to the stressor. In sum, the social stress paradigm in females appears to be a good model for the investigation of the interactions between stress, pregnancy and the immune system. It also provides an excellent platform for studies on prenatal stress under relatively naturalistic conditions.

Abstract
To clarify the cellular immune system in dairy cows with inflammatory diseases after calving, the leukocyte subsets were examined in Holstein dairy cows. Twenty Holstein cows reared in one herd, were used in this study. Nine cows (Group 1) experienced onset of mastitis or puerperal fever within 2 weeks after calving, and the other eleven cows remained healthy (Group 2) after calving. The numbers of CD3(+), CD4(+) and CD8(+) cells tended to be lower in Group 1 than in Group 2 from the day of calving through week 1. These results suggested that the cows with inflammatory diseases might have experienced a decline in T cells by the day of calving, before the onset of disease.

Abstract
The composition and functional capacity of peripheral blood mononuclear leukocyte populations from dairy cows are altered substantially during the peripartal period. These changes are associated with a heightened susceptibility of the mammary gland to infection. It has been postulated that the metabolic demands associated with lactogenesis may impact negatively leukocyte function during the periparturient period. In the present study, serum immunoglobulin G1 concentration and functional capacities of peripheral blood mononuclear leukocytes from intact (n = 6) and mastectomized (n = 6) periparturient Jersey cows were evaluated and compared. Cell function assessments included lymphocyte proliferation, immunoglobulin M secretion, and interferon-gamma secretion by unstimulated and pokeweed mitogen stimulated mononuclear leukocytes. Data were summarized as mean responses for 5-d periods beginning 21 d prepartum and concluding at 19 d postpartum. The progressive decrease in serum immunoglobulin G in intact but not mastectomized cows before parturition likely was attributable to the selective uptake of this isotype by the mammary gland. Lymphocyte proliferation and secretion of interferon-gamma and polyclonal IgM by mitogen-stimulated leukocytes from intact cows decreased during the 15-d period before calving, reaching a nadir at 0 to 4 d postpartum. From 5 to 19 d postpartum, these functions often were comparable to those observed 2 to 3 wk prepartum. Functions of leukocytes from mastectomized cows did not change during the study period, although they often were of lower magnitude than those of cells from nonlactating cows. These results reconfirm the occurrence of a generalized reduction in blood mononuclear leukocyte function during the periparturient period. They also suggest that the reduction in leukocyte function during the period may be, in part, due to the physiologic demands imposed on the dairy cow by the lactating mammary gland.

Abstract
Increased incidence of clinical mastitis in high-yielding cows during early lactation has been attributed to a depressed functional capacity of the immune system. Sympathoadrenal factors are known to play an important role in modulating the host susceptibility and resistance to infectious diseases. Of primary importance in combating acute intramammary infections are polymorphonuclear leukocytes (PMN), as they represent one of the early lines of immunological defense. The release of stress hormones at parturition and during the first weeks of lactation has been proposed to partly contribute to the impaired function of PMN. Here, we summarize the current understanding of the stress-induced peripheral effectors, i.e. the limbs of the sympathetic system and the hypothalamic-pituitary-adrenal axis, on PMN function around parturition and during coliform mastitis. The questions as to whether and how stress induced secretion of glucocorticoids and catecholamines might affect the lactating dairy cow's udder health will be addressed.

Abstract
There is an increased incidence of infectious disease in periparturient dairy cows. During the periparturient period there is a decline in T-lymphocyte cell subsets, which parallels a reduction in functional capacities of blood lymphocytes and neutrophils. Mechanisms responsible for these changes in immune function during the periparturient period are poorly characterized. Ten mastectomized and eight intact multiparous Jersey cows were used to determine whether the periparturient changes in peripheral blood mononuclear cell populations are the result of the physiological demands associated with the onset of lactation or whether they are a result of the act of parturition. Blood mononuclear cells were phenotyped with monoclonal antibodies against T-cell subsets, B-cells, and monocytes. Blood samples were taken frequently from before 4 to 4 wk after parturition. In intact cows, all T-cell subset populations (i.e., CD3-, CD4-, CD8-, and gamma-delta positive cells) decreased at the time of parturition, while the percentage of monocytes increased. Mastectomy eliminated the changes in leukocyte subset populations (CD3-, CD4-, and gamma-delta positive cells, and monocytes) observed in intact cows around parturition. These results indicate that the mammary gland and metabolic stresses associated with lactation influence the composition of peripheral blood mononuclear cell populations in dairy cows during the periparturient period.

Abstract
Induction of adhesion molecules by cytokines and LPS is an important mechanism of regulating leukocyte migration into tissue. Expression and regulation of E-selectin may be differentially influenced by the stimuli involved with effects on mRNA or surface protein kinetics. Surface protein and mRNA expression kinetics of bovine E-selectin were measured and compared in primary cultures of bovine aortic endothelial cells (BAEC) stimulated for various periods of time with recombinant bovine tumor necrosis factor alpha (rbTNF-alpha) or Escherichia coli lipopolysaccharide (LPS). E-selectin mRNA expression was measured via quantitative reverse transcription polymerase chain reaction (Q-RT-PCR) using a construct that contained multiple synthetic oligonucleotides for several bovine adhesion molecules and cytokines. Surface expression of E-selectin was measured by flow cytometry. Unstimulated BAECs expressed minimum or no E-selectin on the surface. A low number of endothelial cells expressed surface E-selectin as early as 1h post-stimulation and surface expression was sustained after both stimuli for 24-72h. Mean fluorescence intensity (MFI) indicated peak surface concentration of E-selectin at 6 h post-stimulation after LPS followed by a gradual decrease to 72h without returning to baseline values. Mean fluorescence intensity following stimulation with TNF-alpha increased slightly between 0 and 72h. The pattern of mRNA expression differed between stimuli. LPS-stimulated BAECs expressed peak amounts of E-selectin mRNA at 6 h, followed by a decline to baseline by 24 h. Conversely, BAECs stimulated with rbTNF-alpha expressed significantly (p pound 0.05) higher amounts of mRNA at 1h than compared to unstimulated controls (0 h), but this decreased to below baseline levels by 6h; followed by a gradual increase and eventually a sharp increase between 18 and 72 h. To account for the lack of correlation between mRNA and protein expression, it was hypothesized that shedding of surface E-selectin accounted at least in part, for the large increase in mRNA expression seen at 18-72h. Culture supernatants from rbTNF-alpha-treated BAECs were harvested, and tested for the presence of shed E-selectin using ELISA. Unstimulated culture supernatants contained little or no E-selectin. Between 6 and 48 h, the concentration of E-selectin in culture supernatants from rbTNF-alpha-stimulated BAECs increased approximately two-fold, suggesting that the sharp increase in E-selectin mRNA expression around 18 h may be related to significant loss of surface E-selectin during this period.

Abstract
Adequate immune functions are essential for the defence against udder infections. Detailed knowledge about the immune response and important defence factors is essential in order to find new ways for the prevention and treatment of udder infections leading to mastitis. Work should be concentrated on ways of minimising the negative influence on immune functions and/or ways of stimulating these functions, especially during periods of immune suppression. A depression of important immune functions has been reported around parturition and there is a higher prevalence of clinical mastitis and other diseases during this period. Immunosuppression is often associated with high levels of glucocorticoids in blood, a common finding around parturition and during stressful conditions. A number of stressors are present around calving, e.g. parturition, onset of lactation and changes in feeding and management regimes. Adequate management including feeding strategies and routines are important for the immune functions. Metabolic stress as well as deficiencies in vitamins and minerals around parturition and during the first month of lactation can have a negative influence on the immune functions and thereby increase the risks for udder infections and mastitis. There seem to be a genetic variability in certain immune functions among periparturient cows. This might indicate a possibility to find markers for genetic selection of individuals with a well-developed immune system without negative effects on milk productivity.

Abstract
Sixteen yearling Holstein steers were fed for 210 or 60% of maintenance requirements to impose positive or negative energy balance, respectively. Blood was collected and analyzed for serum concentration of nonesterified fatty acids (NEFA), and leukocytes were isolated and counted. Isolated leukocytes were then analyzed for expression of the adhesion molecules L-selectin (CD62L), Mac-1 (CD11b and CD18), and major histocompatability complex (MHC) class I and class II molecules with immunostaining and flow cytometric analysis. Negative energy balance increased the concentration of NEFA in serum (P < 0.0001). Expression of CD62L on neutrophils was increased 14% during negative energy balance (P = 0.03). Energy balance did not affect expression of CD62L on any other cell types or expression of CD11b or CD18. Negative energy balance did not affect MHC class I expression but resulted in a small but significant increase in the expression of MHC class II (P = 0.03). The results of this study provide little evidence that nutritionally created negative energy balance impairs expression of CD62L, CD11b, and CD18 or expression of MHC class I or MHC class II molecules by resting bovine blood leukocytes.

Abstract
Dairy cows are highly susceptible to infectious diseases, like mastitis, during the period around calving. Although factors contributing to increased susceptibility to infection have not been fully elucidated, impaired neutrophil recruitment to the site of infection and changes in the concentrations of some micronutrients related with the function of the immune defence has been implicated. Most of the current information is based on studies outside the Nordic countries where the conditions for dairy cows are different. Therefore, the aim of the study was to evaluate changes in blood concentrations of the vitamins A and E, the minerals calcium (Ca), phosphorous (P), and magnesium (Mg), the electrolytes potassium (K) and sodium (Na) and the trace elements selenium (Se), copper (Cu) and zinc (Zn), as well as changes in total and differential white blood cell counts (WBC) and expression of the adhesion molecules CD62L and CD18 on blood neutrophils in Swedish dairy cows during the period around calving. Blood samples were taken from 10 cows one month before expected calving, at calving and one month after calving. The results were mainly in line with reports from other countries. The concentrations of vitamins A and E, and of Zn, Ca and P decreased significantly at calving, while Se, Cu, and Na increased. Leukocytosis was detected at calving, mainly explained by neutrophilia, but also by monocytosis. The numbers of lymphocytes tended to decrease at the same time. The mean fluorescent intensity (MFI) of CD62L and CD18 molecules on blood neutrophils remained constant over time. The proportion of CD62L+ neutrophils decreased significantly at calving. The animals were fed according to, or above, their requirements. Therefore, changes in blood levels of vitamins, minerals and trace elements were mainly in response to colostrum formation, changes in dry matter intake, and ruminal metabolism around calving. Decreased levels of vitamins A and E, and of Zn at calving might have negative implications for the functions of the immune defence. The lower proportion of CD62L+ neutrophils at calving may result in less migration of blood neutrophils into the tissues, and might contribute to the increased susceptibility to infections at this time.

Abstract
OBJECTIVE To investigate risk factors for development of equine protozoal myeloencephalitis (EPM) in horses. DESIGN Case-control study. ANIMALS 251 horses admitted to The Ohio State University Veterinary Teaching Hospital from 1992 to 1995. PROCEDURE On the basis of clinical signs of neurologic disease and detection of antibody to Sarcocystis neurona or S neurona DNA in cerebrospinal fluid, a diagnosis of EPM was made for 251 horses. Two contemporaneous series of control horses were selected from horses admitted to the hospital. One control series (n = 225) consisted of horses with diseases of the neurologic system other than EPM (neurologic control horses), and the other consisted of 251 horses admitted for reasons other than nervous system diseases (nonneurologic control horses). Data were obtained from hospital records and telephone conversations. Risk factors associated with disease status were analyzed, using multivariable logistic regression. RESULTS Horses ranged from 1 day to 30 years old (mean +/- SD, 5.7 +/- 5.2 years). Risk factors associated with an increased risk of developing EPM included age, season of admission, prior diagnosis of EPM on the premises, opossums on premises, health events prior to admission, and racing or showing as a primary use. Factors associated with a reduced risk of developing EPM included protection of feed from wildlife and proximity of a creek or river to the premises where the horse resided. CONCLUSIONS AND CLINICAL RELEVANCE Development of EPM was associated with a number of management-related factors that can be altered to decrease the risk for the disease.
