VETERINARY RESEARCH FORUM : AN INTERNATIONAL QUARTERLY JOURNAL 2024; 15:1-6. [PMID: 38464609 PMCID: PMC10921134 DOI: 10.30466/vrf.2023.2007263.3988] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Accepted: 11/05/2023] [Indexed: 03/12/2024]
Abstract
The present study investigated the prospect of improvement in pharmacokinetic (PK) parameters of marbofloxacin due to alpha-1-monolaurin pre-treatment in broiler chickens. Two groups of broilers were administered a single oral dose of marbofloxacin (5.00 mg kg-1 body weight): Group-I without pre-treatment and Group-II with alpha-1-monolaurin pre-treatment (4.00 g kg-1 feed for 10 days). Blood sampling was done periodically for both groups and plasma marbofloxacin concentrations were determined using ultra-high performance liquid chromatography. Pharmacokinetic parameters using non-compartmental modelling approach were calculated with the PKSolver software. Statistical analysis revealed significant differences in plasma marbofloxacin concentrations between the two groups at 1, 2, and 24 hr. Group-II birds exhibited a higher mean maximum plasma concentration (2.43 µg mL-1) at an earlier time (Tmax: 1.38 hr) compared to Group-I. The plasma concentrations of marbofloxacin were maintained above 0.10 and 0.18 µg mL-1 up to 24 hr in Group-I and Group-II broilers, respectively. Significant differences were observed in PK parameters such as the area under the curve and total body clearance. The mean relative oral bioavailability of Group-II birds compared to Group-I was 119.61%. The findings of the study provided evidence of PK parameters enhancement of marbofloxacin in the alpha-1-monolaurin pre-treated group. The calculated PK-pharmacodynamic indices for marbofloxacin predicted clinical efficaciousness in the broiler chickens.

Abstract
BACKGROUND Sodium butyrate (SB) is a short-chain fatty acid and a safe antibiotic alternative. During 35 days, this study compared the impact of coated SB (Butirex C4) and lincomycin (Lincomix) on broiler growth, gut health, and litter hygiene in 1200 one-day-old Ross-308 broiler chicks that were randomly assigned into 5-dietary groups with 5-replications each. Groups divided as follows: T1: Basal diet (control), T2: Basal diet with buffered SB (1 kg/ton starter feed, 0.5 kg/ton grower-finisher feeds), T3: Basal diet with 100 g/ton lincomycin, T4: Basal diet with buffered SB (0.5 kg/ton starter feed, 0.25 kg/ton grower-finisher feeds) + 50 g/ton lincomycin, and T5: Basal diet with buffered SB (1 kg/ton starter feed, 0.5 kg/ton grower-finisher feeds) + 50 g/ton lincomycin. Birds were housed in a semi-closed deep litter house, where feed and water were available ad libitum. Results were statistically analyzed using ANOVA and Tukey's post hoc tests. RESULTS Combined dietary supplementation with SB and lincomycin (T4 and T5) significantly enhanced body weights, weight gains, feed conversion ratio, and profitability index. Also, carcasses in T4 and T5 exhibited the highest dressing, breast, thigh, and liver yields. T5 revealed the best blood biochemical indices, while T3 showed significantly elevated liver and kidney function indices. T4 and T5 exhibited the highest expression levels of IGF-1 and TLR4 genes, the greatest villi length of the intestinal mucosa, and the lowest levels of litter moisture and nitrogen. Clostridia perfringens type A alpha-toxin gene was confirmed in birds' caeca, with the lowest clostridial counts defined in T4. CONCLUSIONS Replacing half the dose of lincomycin (50 g/ton) with 0.5 or 1 kg/ton coated SB as a dietary supplement mixture showed the most efficient privileges concerning birds' performance and health.

Effects of Lactobacillus plantarum fermented Shenling Baizhu San on gut microbiota, antioxidant capacity, and intestinal barrier function of yellow-plumed broilers. Front Vet Sci 2023; 10:1103023. [PMID: 36908522 PMCID: PMC9992544 DOI: 10.3389/fvets.2023.1103023] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Accepted: 02/03/2023] [Indexed: 02/24/2023] Open
Abstract
The current study focused on the effects of Shenling Baizhu San (SLBZS) fermented by Lactobacillus plantarum (L. plantarum) on gut microbiota, antioxidant capacity, and intestinal barrier function of yellow-plumed broilers. Our results showed that the content of ginsenoside Rb1 was the highest when SLBZS were inoculated with 3% L. plantarum and fermented at 28°C for 24 h. One-day-old male broilers were divided into five treatment groups. Treatment consisted of a basal diet as a control (Con), 0.1% unfermented SLBZS (U-SLBZS), 0.05% fermented SLBZS (F-SLBZS-L), 0.1% fermented SLBZS (F-SLBZS-M), and 0.2% fermented SLBZS (F-SLBZS-H). On days 14, 28, and 42, six chickens from each group were randomly selected for blood collection and tissue sampling. The results showed that the addition of 0.1% fermented SLBZS could significantly increase average daily feed intake (ADFI) and average daily gain (ADG), and decrease feed conversion ratio (FCR) of broilers. The addition of 0.1 and 0.2% fermented SLBZS significantly increased the lymphoid organ index of broilers on day 28 and 42. The addition of 0.1 and 0.2% fermented SLBZS could improve the antioxidant capacity of broilers. Moreover, the addition of 0.1 and 0.2% fermented SLBZS could significantly increase the villus height/crypt depth of the ileum, and significantly increase the expression of tight junction. In addition, fermentation of SLBZS increase the abundance of Coprococcus, Bifidobacterium and Bilophila in the gut of broilers. These results indicate that the supplementation of fermented SLBZS in the diet could improve the growth performance, lymphoid organ index, antioxidant capacity, and positively affect the intestinal health of broilers.

J Anim Sci Biotechnol 2022; 13:144. [PMID: 36522791 PMCID: PMC9756480 DOI: 10.1186/s40104-022-00788-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Accepted: 10/03/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND In China, cage systems with a high space utilization have gradually replaced ground litter systems, but the disease incidence of chickens in cages is higher. Broilers in the ground litter pens may be stimulated by more environmental microbes during the growth process and show strong immune function and status, but knowledge of which microbes and their metabolites play an immunomodulatory role is still limited. This study aimed to explore the differences and correlations in the immune function, gut microbiota and metabolites and the importance of gut microbiota of broilers raised in cages and ground litter pens. METHODS The experiment involved a 2 × 2 factorial arrangement, with rearing systems (cages or ground litter pens) and antibiotic treatment (with or without broad-spectrum antibiotics in drinking water) as factors. RESULTS The results showed that, compared with the cage group, the ground litter broilers had stronger nonspecific immune function (Macrophages% and NO in blood), humoral immune function (IgG in blood, LPS stimulation index in ileum) and cellular immune function (T%, Tc%, ConA stimulation index and cytokines in blood). Antibiotic (ABX) treatment significantly reduced nonspecific immune function (Macrophages% and NO in blood, iNOS and Mucin2 mRNA expression in ileum), humoral immune function (IgG in blood and sIgA in ileum) and cellular immune function (T% and cytokines in blood, Th and Tc ratio, TLRs and cytokines mRNA expression in ileum). Furthermore, the ground litter broilers had higher α diversity of microbiota in ileum. The relative abundance of Staphylococcus, Jeotgalicoccus, Jeotgalibaca and Pediococcus in the ileum of ground litter broilers were higher. ABX treatment significantly reduced the α diversity of ileal microbiota, with less Chloroplast and Mitochondria. In addition, the levels of acetic acid, isobutyric acid, kynurenic acid and allolithocholic acid in the ileum of ground litter broilers were higher. Spearman correlation analysis showed that Jeotgalibaca, Pediococcus, acetic acid, kynurenic acid and allolithocholic acid were related to the immune function. CONCLUSIONS There were more potential pathogens, litter breeding bacteria, short-chain fatty acids, kynurenine, allolithocholic acid and tryptophan metabolites in the ileum of broilers in ground litter pens, which may be the reason for its stronger immune function and status.

Performance and gut health status of broilers fed diets supplemented with two graded levels of a monoglyceride blend. Poult Sci 2022; 102:102359. [PMID: 36512871 PMCID: PMC9763682 DOI: 10.1016/j.psj.2022.102359] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 11/10/2022] [Accepted: 11/15/2022] [Indexed: 11/21/2022] Open
Abstract
The present study was undertaken to evaluate the efficacy of 2 graded levels (0.03 and 0.05% of diet) of a monoglyceride blend containing butyric, caprylic, and capric acids in broilers' diet for optimizing gut structure and animal growth performance. For this purpose, a total of 210, one-day-old male Ross 308 broiler chicks were randomly allocated to 3 experimental treatments using 7 replicates each and 10 birds/replicate. The treatment groups involved supplementation of blend of short and medium chain fatty acids at the level of 0, 0.03, and 0.05% of the diet for 42 d. The incorporation of mixes of monoglycerides into broilers' diet linearly improved BWG between d 0 and 21 (P = 0.034). At the end of trial, however, no significant changes were observed in performance indexes (BWG, FI, FCR). Jejunal morphometric parameters (villus height, crypt depth, and their ratio) remained unaltered with the monoglyceride supplementation on d 21. The results further showed that monoglycerides supplementation increased the goblet cell counts along the jejunal villi (P = 0.034) and crypt regions (P = 0.022), as well as it effectively modulated the mRNA abundances of tight junction protein (ZO-1, P = 0.033) and nutrient transporters (SGLT, PePT1; P = 0.005, 0.023, respectively) in the jejunum. Moreover, the downregulation in mRNA abundance of TNFα (P = 0.030) was observed with the monoglyceride supplementation. The SCFAs analysis of cecal contents showed no notable differences with monoglyceride blend supplementation when compared to the unsupplemented group. Collectively, high goblet cell numbers in the jejunum along with downregulation of the mRNA abundances of pro-inflammatory cytokines, upregulation of tight junction proteins, and nutrient transporters showed favorable responses of low doses of monoglycerides blend in broiler feeding. Further studies should be conducted in different rearing conditions to examine the effectiveness of such low levels of a monoglyceride blend in the modulation of gut structure, its functionality and animal performance.

Abstract
This study aimed to determine whether butyric acid glycerides can replace conventional growth promoters, favour intestinal health, and improve performance. A total of 420 birds were used, divided into four groups with seven repetitions per group (n = 15), as follows: NC, negative control (no promoter); PC, positive control (basal diet + enramycin + salinomycin); MDT-BUT, a diet supplemented with mono-, di-, and triglycerides of butyric acid; TRI-BUT, a diet supplemented with tributyrin of butyric acid glycerides. Productive performance was measured on days 1, 21, 35, and 42. Excreta were collected for counting Escherichia coli and coliforms on days 21 and 42. Blood samples were collected at 42 days of age to analyse oxidant/antioxidant status, and the intestine was removed for intestinal morphometry. From 1 to 42 days, there was greater body weight, weight gain, and feed conversion in the PC, MDT-BUT, and TRI-BUT groups than in the NC group; the production efficiency index was 21.10% higher in all groups than in the NC group (p = 0.001). At 21 days, there were lower E. coli counts of 86.8% in the TRI-BUT and 99.7% in PC groups than in the NC and MDT-BUT groups (p < 0.001), while at 42 days, lower counts were found in the PC, MDT-BUT, and TRI-BUT groups than the NC group (p < 0.001). There were lower total protein and globulin levels in the MDT-BUT and TRI-BUT groups than in the NC group (p = 0.001). Cholesterol levels were lower in the TRI-BUT group, followed by MDT-BUT and PC groups, than in the NC group (p = 0.001), while lower triglyceride levels were found in the TRI-BUT group than in the NC and PC groups (p = 0.001). There were lower levels of lipid peroxidation and reactive oxygen species in the TRI-BUT group, followed by the PC group than the NC group (p < 0.001); on the other hand, there were higher protein thiol levels in the TRI-BUT group than the NC group (p = 0.041). The villus:crypt ratio increase was 79.4% in the TRI-BUT group, followed by the 45.1% PC and 19.8% MDT-BUT groups than the NC (p < 0.001). These findings suggest that adding butyric acid confers antimicrobial and antioxidant activity and improves birds' production efficiency, intestinal health, and metabolism. Butyric acid glycerides are an effective alternative to conventional growth promoters.

Abstract
This experiment was conducted to investigate the effects of dietary supplementation with different levels of coated sodium butyrate (CSB) and polysaccharides extracted from Cordyceps cicadae (CCP) on growth performance, intestinal tissue morphology and ileum microbiome in squabs. A total of 420 1-day-old squabs were randomly divided into seven groups with 5 replicates each and 12 squabs per replicate. The squabs were fed basal diet (control group) and basal diet supplemented with different levels of CSB (275, 550, and 1,100 mg/kg, groups CSB-275, CSB-550, CSB-1100) and CCP (27.5, 55, and 110 mg/kg, groups CCP-27.5, CCP-55, and CCP-110), respectively. The experiment was conducted for 28 days. The results revealed that the final BW and average daily gain concentration were higher (P < 0.05) in squabs of CSB-275 and CCP-110 groups than those in the CON group. Comparing with control group, the squabs in the groups CSB-275, CSB-550, and CCP-55 obtained higher villus height/crypt depth (VH/CD) of the duodenum and higher VH of the jejunum (P < 0.05). Operational taxonomic units in the groups CSB-550 and CCP-27.5 were also increased (P < 0.05). Regarding the relative abundance of flora, the Actinobacteria abundance in the groups CSB-550, CSB-1100, and CCP-55 were higher than in control group (P < 0.05), and the Aeriscardovia abundance of CSB-275, CSB-550, CSB-1100, and CCP-110 were elevated (P < 0.05). However, the Enterococcus abundance in CSB-275, CSB-550, CSB-1100, and CCP-27.5 decreased (P < 0.05). In summary, results obtained in the present study indicate that CSB and CCP can improve growth performance, intestinal microbial balance and gut health of squabs.

Monolaurin Confers a Protective Effect Against Porcine Epidemic Diarrhea Virus Infection in Piglets by Regulating the Interferon Pathway. Front Immunol 2022; 12:797476. [PMID: 35095875 PMCID: PMC8793282 DOI: 10.3389/fimmu.2021.797476] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 12/27/2021] [Indexed: 01/14/2023] Open
Abstract
Porcine epidemic diarrhea virus (PEDV) has reemerged as the main pathogen of piglets due to its high mutation feature. Monolaurin (ML) is a natural compound with a wide range of antibacterial and antiviral activities. However, the role of ML in PEDV infection is still unknown. This study aimed to evaluate the effect of ML on the growth performance, intestinal function, virus replication and cytokine response in piglets infected with PEDV, and to reveal the mechanism through proteomics analysis. Piglets were orally administrated with ML at a dose of 100 mg/kg·BW for 7 days before PEDV infection. Results showed that although there was no significant effect on the growth performance of piglets, ML administration alleviated the diarrhea caused by PEDV infection. ML administration promoted the recovery of intestinal villi, thereby improving intestinal function. Meanwhile, PEDV replication was significantly inhibited, and PEDV-induced expression of IL-6 and IL-8 were decreased with ML administration. Proteomics analyses showed that 38 proteins were differentially expressed between PEDV and ML+PEDV groups and were significantly enriched in the interferon-related pathways. This suggests ML could promote the restoration of homeostasis by regulating the interferon pathway. Overall, the present study demonstrated ML could confer a protective effect against PEDV infection in piglets and may be developed as a drug or feed additive to prevent and control PEDV disease.
