Abstract
Plasma is a co-product from pork and beef obtained during the processing of animals for human consumption. The spray-drying process maintains the solubility of spray-dried animal plasma (SDAP) and its nutritional and functional properties, making this ingredient multifunctional in human and animal nutrition. In pet food, SDAP has been used in the production of wet foods (pates and chunks in gravy) as an emulsifying and binding agent, with the potential to replace hydrocolloids partially or totally, which have some negative implications for digestibility, fecal quality, and intestinal inflammation. From a nutritional point of view, SDAP has high digestibility and an amino acid profile compatible with high-quality ingredients, such as powdered eggs. Studies in companion animals, especially in cats, have shown that SDAP is an ingredient with high palatability. Despite the immunomodulatory, anti-inflammatory, prebiotic, and neuroprotective properties demonstrated in some animal models, there are still few publications demonstrating these effects in dogs and cats, which limits its use as a functional ingredient for these species. In this review, the potential use of SDAP in pet food, aspects related to the sustainability of this ingredient, and opportunities for studies in companion animals are discussed.

Spray-Dried Plasma Improves Body Weight, Intestinal Barrier Function, and Tibia Strength during Experimental Constant Heat Stress Conditions. Animals (Basel) 2021; 11:ani11082213. [PMID: 34438670 PMCID: PMC8388371 DOI: 10.3390/ani11082213] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 07/01/2021] [Accepted: 07/04/2021] [Indexed: 01/16/2023] Open
Abstract
Simple Summary Broilers are especially heat sensitive because of the absence of sweat glands and their elevated metabolism. Under commercial conditions, extremely high temperatures (heat stress) reduce their performance. This research aimed to assess spray-dried feeding plasma (SDP) during constant heat stress (HS) on the performance, intestinal permeability, and bone strength in broilers. Chickens fed with a diet supplemented with SDP increased both their body weight and body weight gain compared to the HS control group. At the end of the study (d 42 of age), chickens fed with SDP significantly alleviated the increased gut leakage induced by HS and showed a significant increase in tibia strength compared with control HS chickens. The results in the present study suggest SDP mends gut integrity, hence reducing chronic systemic inflammation. Abstract The aim of this study was to see how spray-dried plasma (SDP) supplementation affected broiler chicken performance, intestinal permeability, and bone strength during persistent heat stress. One-day-old chicks (n = 480) were randomly assigned into twelve environmental corrals; four thermoneutral (TN-negative control, maintained at 24 °C from d 21–42); four heat stress (HS, exposed to 35 °C from d 21–42); and four heat stress treated with 2% SDP in the feed until d 28 followed by 1% SDP until d 42 (HS-SDP). The performance and serum levels of fluorescein isothiocyanate-dextran (FITC-d) were evaluated at d 21, 28, 35, and 42. The tibias strength was evaluated on d 21 and 42. The increment in chicken temperature (p < 0.05) was observed two h following the increase in environmental temperature in both HS groups and was associated with decreased performance parameters compared with the TN group. At d 42 of age, the chickens exposed to HS had an impaired gut permeability and decreased tibia strength compared to the TN group (p < 0.05). However, partially feeding SDP mitigated these adverse effects significantly. These findings imply that using SDP strategically during stressful times, such as prolonged heat stress, may help mitigate its negative consequences.

Abstract
Spray-dried animal plasma sourced from bovine, porcine or other animal origin is often used as a main feed ingredient in the diets of weanling piglets to improve growth performance. The objective of this study was to determine the effect of animal plasma in diets on the performance of piglets in the post-weaning period, with and/or without pathogenic challenge, by undertaking a meta-analysis. Data were extracted from peer-reviewed reports published in scientific journals. The average initial weight of the piglets was 5.8 kg and the average initial age 19 days (2-56 days). The average duration of feeding animal plasma was 40 days. Average daily gain (ADG), feed intake (ADFI) and feed conversion ratio (FCR) were found to be 22-28 g/day, 20-27 g/day and -0.28 to 0.06 g/g. Generally, diet supplemented with spray-dried bovine plasma (SDBP) improved the ADG of the piglets and spray-dried porcine plasma (SDPP) led to increases in the ADFI. For the first week post-weaning alone, as the dietary animal plasma percentage increased there was an increase in ADG and ADFI; similarly, the latter two measures increased as weaning age increased. The evidence suggests that mainly IgG present in animal plasma prevents the binding of pathogens to the gut wall and reduces the incidence of sub-clinical infection in the post-weaning stage. Animal plasma containing IgG appears to be a useful in-feed supplement for piglets in the post-weaning phase.

Abstract
Spray-dried plasma (SDP) is a functional ingredient commonly utilized in swine production and calf milk replacers to improve performance, feed efficiency, and health. The improvements noted with SDP in animal production are more pronounced under commercial production conditions compared to cleaner research settings. Multiple modes of action of SDP have been proposed, including either directly influencing the immune inflammatory response locally or systemically, and/or through the indirect modification of beneficial microbial populations. Spray-dried plasma included at various dietary levels and duration of feeding in broilers has been evaluated in different production and challenging conditions with beneficial effects on broiler performance, as noted in other animals. The purpose of this review is to discuss research related to the modes of action of SDP on immunomodulation and improved intestinal health and specifically discuss research conducted utilizing SDP in feed for poultry. Collectively, the data available indicates that SDP improves early intestinal health and supports an efficient immune system response both locally at the intestine and systemically, thereby benefiting growth, feed efficiency, and survival of broilers in conventional commercial production and under challenging conditions such as disease or environmental stressors.

Abstract
Immunoglobulin (Ig) is the one of the main anti-infective components of blood, colostrum and breast milk. It is the unique glycoprotein that defends the body from harmful bacteria, viruses and other environmental pathogens by either binding to them or by forming an encapsulating barrier. The expansion of antimicrobial and immunomodulatory products from natural sources for dietary supplementation in both animals and humans is an ever growing and thriving area of research. Purified Ig from sheep serum (ovine serum Ig) is one such candidate product. Recent work has shown the various biological effects of oral Ig in different animal models including its effect on growth, immunity, intestinal growth and gut barrier function. The objective of this paper is to review the results of recent studies demonstrating the effects of oral Ig in both pathogenic and non-pathogenic animal models and to suggest a possible mechanism of its action. Overall, purified oral Ig improves growth of healthy (and challenged) rats and defends against enteric infection by immunomodulation, mucin protein and/or modification of commensal microbial composition. The findings contribute to knowledge of how orally administered ovine Ig can influence and enhance key indicators of gut function and overall growth performance in an animal model.

Abstract
The objective of this study was to evaluate the effects of spray-dried porcine plasma (SDPP) on performance, measurement of thyroid hormones triiodothyronine (T3) and thyroxine (T4), body temperature and relative organ weights of weaned piglets exposed to a heat stress or a thermoneutral environment. One hundred and forty-four piglets with initial BW of 5.82 ± 0.33 kg (28 d old) were used. The experimental design was a 4 x 2 factorial arrangement, four plasma levels (0.0, 2.5, 5.0 and 7.5%) and two environments (34º [heat stress (HS)] and 24°C [thermoneutral (TN)]). SDPP was fed from weaning (28 d of age) to the end of the trial (piglets were weighed at the beginning, 7, 21 and 35 days of trial). Rectal, neck, shoulder and leg temperatures were measured every seven days. At 21 days of trial, one piglet per pen was slaughtered to determine the weight of the carcass and organs. Blood samples were collected at 18 and 35 days of trial to determine levels T3 and T4. The rectal, neck, shoulder and leg temperatures were increased (p < 0.05) 0.4, 1.5, 1.0 and 1.3ºC, respectively, and relative weight of the lungs (p < 0.05) and total T3 (p < 0.05) were decreased 0.001 kg/kg and 0.19 ng/dl, respectively, for pigs in the HS environment. The estimated inclusion of 5.1% of SDPP had the greatest (p < 0.05) weight gain during the first week, and throughout the nursery phase, the 5% of inclusion had a tendency of improvement (p = 0.075), regardless of ambient temperature. For the entire period, pigs reared in the HS environment had the greatest (p < 0.05) estimated feed intake by the quadratic regression with the inclusion of 4.3% of SDPP.

The Anti-Inflammatory Effect of Spray-Dried Plasma Is Mediated by a Reduction in Mucosal Lymphocyte Activation and Infiltration in a Mouse Model of Intestinal Inflammation. Nutrients 2016; 8:nu8100657.

Abstract
Spray-dried preparations from porcine and bovine plasma can alleviate mucosal inflammation in experimental models and improve symptoms in patients with enteropathy. In rodents, dietary supplementation with porcine spray-dried plasma (SDP) attenuates intestinal inflammation and improves the epithelial barrier function during intestinal inflammation induced by Staphylococcus aureus enterotoxin B (SEB). The aim of this study was to discern the molecular mechanisms involved in the anti-inflammatory effects of SDP. Male C57BL/6 mice were fed with 8% SDP or control diet (based on milk proteins) for two weeks, from weaning until day 33. On day 32, the mice were given a SEB dose (i.p., 25 µg/mouse) or vehicle. SEB administration increased cell recruitment to mesenteric lymph nodes and the percentage of activated Th lymphocytes and SDP prevented these effects). SDP supplementation increased the expression of interleukin 10 (IL-10) or transforming growth factor- β (TGF-β) compared to the SEB group. The SEB challenge increased six-fold the expression of mucosal addressin cell adhesion molecule 1 (MAdCAM-1) and intercellular adhesion molecule 1 (ICAM-1); and these effects were attenuated by SDP supplementation. SEB also augmented NF-κB phosphorylation, an effect that was prevented by dietary SDP. Our results indicate that the anti-inflammatory effects of SDP involve the regulation of transcription factors and adhesion molecules that reduce intestinal cell infiltration and the degree of the inflammatory response.

Abstract
Studies administering plasma protein isolates (PPIs) to experimentally challenged animals have reported improvements in growth, food intake, and overall condition when compared with animals fed control diets, due in part to improvements in gut barrier function, normalization of cytokine signals, and support of enteric immune function. These and early clinical studies suggest that nutritional therapy with PPIs may similarly assist in restoring homeostasis to gut barrier function in humans experiencing mild or more acute enteropathic symptomatology such as irritable bowel syndrome and inflammatory bowel disease. This meta-analysis evaluated the ability of PPIs to promote weight gain and food intake in weanling animals, primarily piglets, after oral challenge with various enteric pathogens or bacterial toxins. MEDLINE, EMBASE, and PubMed were searched from 1980 through August 2012 for specified terms and keywords. Twenty-nine articles retrieved through this process were evaluated; 11 studies including 13 experiments were selected for inclusion in the analysis. The meta-analysis included descriptive analyses and methods for combining P values for the primary endpoint, average daily growth (ADG) at week 1, and secondary endpoints including ADG, average daily feed intake (ADFI), and gain to feed ratio (G:F) at weeks 1 and 2 and at the end of study. Primary and secondary endpoint analyses of growth (ADG, ADFI, and G:F) were significant (P < 0.01). The proinflammatory cytokines interleukin (IL) 1β, IL-6, and tumor necrosis factor α were significantly lower in animals fed dietary PPIs. Additional research in patients experiencing symptoms of enteropathy will further characterize the benefits of PPIs in clinical populations.

Abstract
In poultry nutrition, most attention is given to protein products, due to the importance of protein as a major constituent of the biologically active compounds in the body. It also assists in the synthesis of body tissue, for that renovation and growth of the body. Furthermore, protein exists in form of enzymes and hormones which play important roles in the physiology of any living organism. Broilers have high dietary protein requirements, so identification of the optimum protein concentration in broiler diets, for either maximizing broiler performance or profit, requires more knowledge about birds' requirements for protein and amino acids and their effects on the birds' growth performance and development. It also requires knowledge about the protein sources available that can be used in poultry diets. The broad aim of this review is to highlight the importance of some of the available high-quality specialized protein products of both animal and plant origins which can be explored for feeding broiler chickens. Minimization of the concentration of anti-nutritional factors (ANFs) and supplementation with immunologically active compounds are the main focus of gut health-promoting broiler diets. These diet characteristics are influenced by feed ingredient composition and feed processing. The general hypothesis is that these protein products are highly digestible and devoid of or contain less ANFs. Feeding these products to broiler chicks, especially at an earlier age, can assist early gut development and digestive physiology, and improve broiler growth performance and immunity.

Abstract
Pigs from 154 litters (n = 1132, 19 ± 3 days of age, 4.9 ± 1.1 kg of bodyweight) were used in a 3 × 2 factorial design to evaluate two raw materials with nutraceutical properties being used in feeds, spray-dried porcine plasma (SDPP) and a yeast protein meal, and their effects on growth performance, immune parameters and gastrointestinal adaption of piglets to weaning. Factors included dietary treatments being (1) 5% SDPP (PLA), (2) 3.5% yeast protein meal (NUP) and (3) medicated control (TMC) and parity (primiparous versus multiparous). The treatment groups were imposed from Day 19 through to weaning at Day 27. Selected pigs (n = 720, 28 ± 3 days of age, 7.4 ± 1.0 kg of bodyweight) were weaned and remained on their respective diets from Day 28 to Day 34. From Day 35 to Day 48 all group-housed pigs were offered a commercial weaner 1 diet, and from Day 49 to Day 68 pigs were offered a commercial weaner 2 diet. Growth performance, survival, and serum immunoglobulin G were monitored throughout the nursery phase (Day 28 to Day 68). Adaptation of the gastrointestinal tract in the acute post-weaning phase (Day 28 to Day 34) was assessed in 36 individually housed male weaners, with the effects of feed on structural, digestive, microbial and immune parameters along the gastrointestinal tract determined at Day 34. Pre-weaning feed disappearance was greater (P < 0.01) in multiparous litters independent of diet. In the commercial nursery, total removals (mortality and morbidity) were highest (P < 0.01) in primiparous sow progeny, with pigs offered NUP having greater (P ≤ 0.05) total removals. Pigs offered PLA had superior average daily gain, average daily feed intake and feed conversion ratio from Day 28 to Day 34 (P < 0.05). Pigs offered NUP tended to (P = 0.07) have superior average daily gain from Day 35 to Day 49. Pigs offered NUP had higher (P < 0.05) serum immunoglobulin G concentrations at Day 68 compared with pigs offered TMC, with the effect most pronounced in primiparous sow progeny. Individually housed weaners offered PLA consumed more (P < 0.05) feed on Day 30 to Day 31, had shorter relative intestine length (P < 0.05), greater villous height in the medial jejunum (P < 0.10) and lower immuno-pathology scores along the intestine. Pigs offered PLA also tended (P < 0.10) to have increased pancreatic-specific lipase and amylase activity compared with pigs offered NUP. Pigs offered NUP had a higher ratio of E. coli : coliforms in the colon (P < 0.01) and more counts of β-haemolytic bacteria in the medial jejunum (P < 0.05) and colon (P < 0.10). Diets containing either SDPP or NUP offered pigs benefits beyond nutrition relative to the medicated control diet. The benefits of SDPP were highly effective but transient, while the yeast derived protein had a successive or accumulative effect which was more pronounced in primiparous sow progeny.

Abstract
The epithelial barrier of the intestine and the gut-associated lymphoid tissue (GALT) protects the host against luminal pathogenic micro-organisms. This is important at weaning, when animals are exposed to infectious agents and stresses. We have developed a rat model of intestinal inflammation post weaning, based on the systemic administration of Staphylococcus aureus enterotoxin B (SEB). Since the inflammatory response obtained is mild, the food intake pattern is not affected, which makes this model useful for studies of nutritional therapies for intestinal inflammatory disease. SEB increased T-lymphocytes in Peyer's patches and the number of activated T-lymphocytes in mesenteric lymph nodes (organized GALT). In the lamina propria, SEB increased activated T-lymphocytes as well as cytotoxic and natural killer-cell populations of the diffuse GALT. It also increased pro-inflammatory cytokines and inflammatory mediators in both Peyer's patches and mucosa. Rats given SEB had higher paracellular permeability to macromolecules, which was associated with a reduction in epithelial tightness. This model was used to examine whether dietary supplementation with spray-dried animal plasma proteins affects intestinal inflammation. Results showed that dietary plasma proteins can attenuate the mucosal immune response in both organized and diffuse GALT and that these effects are mediated by a reduction in the production of pro-inflammatory cytokines.

Abstract
Spray-dried plasma (SDP) is a complex mixture of active proteins that modulates the immune response of gut-associated lymphoid tissue. We examined whether SDP and Ig concentrate (IC) supplementation could modulate cytokine expression and inflammatory mediators in rats challenged with Staphylococcus aureus enterotoxin B (SEB). Wistar-Lewis rats were fed diets supplemented with SDP (8% wt:wt), IC (1.5% wt:wt), or milk proteins (control diet) from weaning (d 21) to d 34 after birth. On d 32 and 35, the rats were given SEB (0.5 mg/kg; intraperitoneal). Six hours after the second SEB dose, jejunal mucosa and Peyer's patches (PP) from the small intestine were collected. The cytokines interferon-gamma (IFNgamma), tumor necrosis factor-alpha (TNFalpha), interleukin (IL)-6, IL-10, transforming growth factor-beta (TGFbeta), and leukotrienne B(4) (LTB(4)) were analyzed using commercial kits. SEB increased the release of proinflammatory mediators (IFNgamma, TNFalpha, IL-6, and LTB(4)) in PP (P < 0.05) and in the mucosa (P < 0.05). In both tissues, SDP prevented the increase in IFNgamma, IL-6, and LTB(4) induced by SEB (P < 0.05). IC reduced the expression of TNFalpha and LTB(4) in PP and mucosa (P < 0.05). SDP supplementation increased IL-10 and mature TGFbeta concentrations in intestinal mucosa from both inflamed and noninflamed rats. Both SDP and IC increased the mature:total TGFbeta ratio (all P < 0.05). Both supplements were effective at preventing the SEB-induced increase in proinflammatory:antiinflammatory cytokine ratios in PP and mucosa and in serum. The preventive effects of plasma supplements on intestinal inflammation involve modulation of intestinal cytokines, characterized by an increased expression of antiinflammatory cytokines.

Abstract
In this study, our aim was to determine whether orally administered ovine serum Ig improved growth performance, organ weights, and gut morphology in growing rats and whether the method of manufacture of ovine serum Ig affected its bioactivity. Ninety Sprague-Dawley male rats were used in a 21-d growth study and were fed a basal control diet (BD; no Ig) and 5 test diets: spray-dried porcine plasma (SDPP), freeze-dried ovine Ig (FDOI), 2 concentrations of spray-dried ovine Ig (SDOI(100) and SDOI(150)), and inactivated ovine Ig (IOI). Diets were isocaloric and contained the same amount of the first limiting amino acids, methionine plus cysteine. The body weight gain:feed ratio was higher (P < 0.05) for the FDOI-fed rats than for the BD- and IOI-fed groups. FDOI rats had higher jejunum (P < 0.05) and colon weights (P < 0.05) at the end of the study than rats in the BD group. Compared with the SDOI(100)-fed group, the FDOI group supported higher (P < 0.05) duodenum and colon weights. For gut morphology, the FDOI and the BD and IOI groups differed (P < 0.05). The FDOI-fed rats had longer (P < 0.05) villi and greater villi surface areas in the duodenum, jejunum, and ileum than the rats fed SDOI(100). An ovine Ig fraction selectively improved growth performance, organ weight, and gut morphology in growing rats. Compared with spray-drying, a freeze-drying procedure appears to preserve a higher degree of immunological activity.

Abstract
The intestinal mucosa contributes to homeostasis by preventing the entrance of biological and chemical agents across the epithelium that could alter the stability of the system. This protective function is especially important at the time of weaning, when animals are exposed to infectious agents and to numerous stresses such as the change of environment and diet. Diets supplemented with spray-dried plasma or plasma protein fractions have been shown to improve growth performance of farm animals and have been proposed as an alternative to antibiotics. In this review, we summarize our findings on the mechanism of action of dietary plasma proteins using a rat model of intestinal inflammation, based on the administration of Staphylococcus aureus enterotoxin B (SEB). Staphylococcal enterotoxin B activates the gut-associated lymphoid tissue (GALT), increasing T-lymphocytes in Peyer's patches and the number of activated T lymphocytes in mesenteric lymph nodes (organized GALT). In the lamina propria SEB increased cytotoxic T δγ and natural killer cell populations of the diffuse GALT. Staphyloccocal enterotoxin B significantly increased proinflammatory cytokines in Peyer's patches and mucosa. Plasma protein supplements modulated the mucosal immune response in organized and diffuse GALT, protecting GALT from possible excessive activation by the SEB challenge. These effects are accompanied by a reduction of proinflammatory cytokine production, supporting the view that changes in cytokine production mediate the effects of dietary plasma proteins during intestinal inflammation. The increase in mucosal permeability and intestinal secretion induced by SEB was associated with decreased expression of mucosal tight-junction and adherent-junction proteins. Both plasma and plasma protein fractions prevented the effects of SEB on intestinal permeability, thus reducing the exposure of the host to microbial and food antigens across the interstitial space. These findings indicate that dietary plasma proteins modulate functional and structural properties of the intestinal mucosa.

Abstract
We have previously shown that plasma protein supplementation prevents the activation of lymphocyte populations of Peyer's patches and mesenteric lymph nodes, which is known as organized gut-associated lymphoid tissue (GALT). Here, we examined the effects of spray-dried plasma proteins (SDAP) and Ig concentrate (IgC) supplements on lamina propria and intraepithelial lymphocytes (diffuse GALT) in a model of mild intestinal inflammation induced by the intraperitoneal administration of Staphylococcus aureus enterotoxin B (SEB). Wistar-Lewis rats were fed diets supplemented with SDAP (8% wt:wt), IgC (1.5% wt:wt), or bovine milk proteins (control diet) from weaning (d 21) to d 34 after birth. On d 30 and 33, rats were given SEB (0.5 mg/kg body weight) or PBS (control). Experimental groups were designated control, SEB, SEB-SDAP, and SEB-IgC. Lymphocyte populations were analyzed by immunohistochemistry. In lamina propria, SEB increased the cytotoxic lymphocyte populations of T-gammadelta cells (38%; P < 0.001) and natural killer cells (59%; P < 0.05) and the number of activated T lymphocytes (148%; P < 0.001). Both SDAP and IgC decreased the effects of SEB on these lymphocyte subsets (P < 0.05). In the epithelium, SEB induced a 117% increase in intraepithelial-activated lymphocytes that was reduced by SDAP supplementation (P < 0.01). The effects of plasma supplements on intestinal lymphocyte populations suggest that oral plasma proteins can modulate the degree of activation of diffuse GALT.

Abstract
Four experiments involving 265, 410, 894, and 554 sows (Exp. 1 to 4, respectively) were conducted to determine the effect of spray-dried plasma (SDP) at 0 or 0.25% (Exp. 1 and 2) and 0 or 0.50% (Exp. 3 and 4) in lactation diets on average daily feed disappearance (FD), sum of sow BW, fetal and placental loss from d 110 gestation to weaning (SWL), litter size at weaning, litter weight at weaning, and average days from weaning to first estrus (WEI). Experiments 1, 3, and 4 were conducted during summer months, and Exp. 2 was conducted during fall to winter months. Experiment 1 used only parity 1 and parity 2 sows and Exp. 4 used only mature (>2 parities) sows, whereas Exp. 2 and 3 used all parity groups. Sows fed SDP in Exp. 1 had increased (P < 0.01) FD and a tendency for reduced (P = 0.06) SWL and WEI (P = 0.06). Sows fed SDP in Exp. 2 had a tendency for increased (P = 0.09) sow BW at weaning and reduced (P = 0.09) SWL, whereas other variables were not different between diets. Parity 1 and 2 sows fed SDP in Exp. 3 had increased (P < 0.01) FD, but mature sows fed SDP had reduced (P = 0.02) FD. Pig survival and litter size at weaning for all parity groups was not different between diets. The WEI for parity 1 sows fed SDP was reduced (P = 0.02) and tended to be reduced (P = 0.10) for mature sows fed SDP, but was not different between diets for parity 2 sows. More parity 1 sows fed SDP were detected (P = 0.01) in estrus 4 to 6 d after weaning, and fewer were detected (P < 0.01) in estrus 6 d after weaning compared with control parity 1 sows. In Exp. 4, FD was reduced (P < 0.01) for mature sows fed SDP; however, litter weight and average pig BW at weaning was increased (P < 0.01) with more (P < 0.01) marketable pigs (pig BW > 3.6 kg) weaned per litter. Relatively low dietary levels of SDP (0.25 to 0.50%) fed to parity 1 sows farrowed during summer months increased lactation FD and reduced WEI. Mature sows fed SDP during summer months consumed less lactation feed without compromising WEI, but had an increased litter weight, average pig BW, and number of marketable pigs at weaning.

Abstract
In this study, we investigated intestinal barrier function during inflammation as well as the effects of dietary supplementation with porcine spray-dried animal plasma (SDAP) proteins and porcine immunoglobulin concentrate (IC). Wistar Lewis rats were fed from d 21 (weaning) until d 34 or 35 either a control diet or a diet containing SDAP or IC. On d 30 and d 33, rats received an intraperitoneal dose of Staphylococcus aureus enterotoxin B (SEB; 0.5 mg/kg body wt; groups SEB, SEB-SDAP, and SEB-IC). SEB reduced the potential difference across the jejunum by 60%, the short-circuit current by 70%, and Na-K-ATPase activity in intestinal mucosa (all P < 0.05). The fluxes of dextran flux (4 kDa) and horseradish peroxidase (HRP, 40 kDa) across the intestinal wall also increased in SEB-treated rats (P < 0.01, P = 0.068, respectively). SEB also increased HRP flux across the paracellular space (P < 0.05). Moreover, SEB-treated rats had a reduced expression of tight junction proteins, such as ZO-1 (10% reduction; P < 0.05) and beta-catenin (20% reduction; P < 0.05). Dietary supplementation with SDAP or IC prevented dextran (P < 0.05) and HRP (P < 0.05) paracellular flux across the intestinal epithelium. SDAP supplementation also prevented SEB effects on Na-K-ATPase activity (P < 0.05). In our model of SEB-induced intestinal inflammation, the increased permeability across the intestinal mucosa was due to the lower expression of tight junction proteins, an effect that can be prevented by both SDAP and IC supplementation.

Abstract
Experimental models of hypertension, such as spontaneously hypertensive rats (SHR), show alterations in cellular sodium transport that affects Na+-coupled cotransport processes and has been involved in the pathogenesis of this disease. The objective of the present study was to analyze the kinetic properties of the sodium-dependent glucose transport in the jejunum and ileum of SHR and its genetic control, Wistar-Kyoto (WKY) rats, as well as the regulation of the transporter, SGLT1. In hypertensive rats, the increased systolic blood pressure was accompanied by an enhancement of serum aldosterone levels compared with WKY rats, but no alterations were found in their body weight or serum glucose/insulin levels. The values for d-glucose maximal rate of transport (Vmax) were 42 and 60% lower, respectively, in the jejunum and ileum of SHR than those from WKY rats. On the other hand, the values for the Michaelis constant (Km) were similar in both animal groups, as was the diffusive component of transport (Kd). Immunoblotting and Northern blot analysis revealed the existence of a lower abundance of SGLT1 protein and mRNA in SHR. Moreover, hypertensive rats showed a decrease in the molecular mass of SGLT1 that could not be explained in terms of different glycosylation and/or phosphorylation levels or an alternative splicing in the expression of the protein. These findings demonstrate that SGLT1 is regulated at a transcriptional level in the intestine of hypertensive rats, and suggest that this transporter might participate in the dysregulation of sodium transport observed in hypertension.

Abstract
In chickens, elevated environmental temperature reduces food intake. We have previously reported that, during heat stress, the intestinal mucosa has an increased capacity to take up sugars. To investigate whether the effects of warm environment on sugar uptake are an intestinal adaptation to lower energy intake or a response attributable to heat stress, we examined the glucose transport kinetics of apical and basolateral membranes of the jejunum and the mucosal morphology of broiler chickens maintained in climatic chambers for 2 wk. Experimental groups were 1) control ad libitum (CAL), fed ad libitum and in thermoneutral conditions (20 degrees C); 2) heat stress ad libitum (HSAL), fed ad libitum and kept in a heated environment (30 degrees C); and 3) control pair-fed (CPF), maintained in thermoneutral conditions and fed the same amount of food as that consumed by the HSAL group. Both the CPF and the HSAL groups showed reduced body weight gain, but only the HSAL chickens had lower plasma thyroid hormones and higher corticosterone than CAL and CPF groups. The fresh weight and length of the jejunum were only reduced in the HSAL group. The activity and expression of apical sodium-dependent glucose transporter 1 (SGLT-1) were increased by approximately 50% in the HSAL chickens, without effects in the CPF group. No changes in K(d) or in SGLT-1 and glucose transporter-2 K(m) were observed in the pair-fed and heated birds. These results support the view that increased intestinal hexose transport capacity is entirely dependent on adaptations of apical SGLT-1 expression to heat stress and is not due to reduced food intake.
