Abstract Background: The effects of dietary supplementation with guava leaf extracts (GE) on growth performance, diarrhea and intestinal barrier function, as well as associated with its modulation of serum and fecal metabolic changes in weaned piglets challenged by enterotoxigenic Escherichia coli (ETEC) were investigated.Method: Fifty weaned piglets (Duroc × Yorkshire × Landrace) from 5 pens (2 piglets per pen) were randomly divided into five groups: blank control group (BC), negative control group (NC), or those supplemented with 50 mg kg-1 (S50), 100 mg kg-1 (S100), or 200 (S200) mg kg-1 diet GE, respectively. On day 4, all piglets (except for BC) were orally challenged with about 1.0 × 109 colony-forming units (CFU) enterotoxigenic ETEC. After 28-day trial, growth performance, diarrhea incidence, intestinal barrier function and metabolomics of serum and fecal were investigated.Results: We demonstrated that dietary supplementation with GE (50-200 mg kg-1) reduced diarrhea incidence of piglets and increased expression of intestinal tight junction proteins (ZO-1, Occludin, Claudin-1) (P < 0.05) and sodium hydrogen exchanger 3 (NHE3) (P < 0.05). Moreover, dietary supplementation with GE (50-200 mg kg-1) upregulated level of tetrahydrofolic acid (THF) and reversed higher level of nicotinamide-adenine dinucleotide phosphate (NADP) caused by ETEC in serum compared with NC group (P < 0.05), and enhanced antioxidant ability of piglets. In addition, dietary addition with GE (100 mg kg-1) reversed the lower level of L-pipecolic acid caused by ETEC in feces compared with NC group (P < 0.05), and decreased oxidative stress response of piglets. Further, there were no differences (P > 0.05) in the final weight, average daily feed intake (ADFI) and F/G among dietary groups during the overall period, and piglets in S50 group has the higher average daily gain (ADG). Conclusion: Dietary supplementation with 50-200 mg kg-1 GE reduced diarrhea incidence of weaned piglets challenged by ETEC and exhibited positive effect on improving intestinal barrier function. Meanwhile, dietary addition with GE organized and redistributed energy resources through similar or dissimilar metabolic pathways, and finally enhanced antioxidant ability of piglets challenged by ETEC.

Fermented Feed

Abstract BACKGROUND: The beneficial function of fermented feed in livestock industry has been widely investigated. However, little is known about the effects of fermented feed on different weaned-day piglets. This study aimed to investigate the effects of fermented diet on the growth performance, intestinal function and microbiota of piglets weaned at age of 21 days and 28 days.RESULTS: The results found that weaning on d 21 significantly increased (P < 0.05) ADG, and ADFI (calculated based on wet weight and dry matter), while reduced (P < 0.05) F: G, the activities of trypsin and lipase of jejunum and villus height of ileum, compared with 28-d weaning. The protein levels of Occludin, Claudin-1, ZO-1 of ileum in the groups weaning on d 21 were less (P < 0.05) than the groups weaning on d 28. Moreover, dietary supplementation with fermented diet upregulated (P < 0.05) Occludin, Claudin-1, ZO-1 proteins of ileum, compared with the groups treated with control diet both weaning on d 21 and d 28. In addition, dietary supplementation with fermented diet decreased (P < 0.05) the relative abundance of Clostridia (class) and increased (P < 0.05) Bacteroidia (class) level of cecal microbiota, compared with the groups treated with control diet both weaning on d 21 and d 28. However, supplementation with fermented diet did not affect the concentrations of short-chain fatty acids in the cecum (P > 0.05).CONCLUSION: Therefore, our data suggest that feed digestibility is improved in piglets weaned at 21 days, but intestinal barrier function is weaker than in piglets weaned at 28 days. However, compared with feeding control diet, supplementation with fermented diet both improved feed conversion and intestinal barrier function of weaned piglets by modulating intestinal microbiota.

Intestinal Pathogens

Abstract Background Necrotic enteritis (NE), which is caused by Clostridium perfringens (C. perfringens), is an economically important disease in broiler. Among normal flora in the broiler intestinal, Clostridium butyricum (C. butyricum) has been identified as a probiotic agent that reduces the susceptibility of broilers to C. perfringens. It also promotes the repair of broiler intestinal damage from harmful intestinal pathogens. However, the effects of C. butyricum infection on broiler intestinal integrity during NE are largely unknown. In this study, we investigated the effects of C. butyricum on the growth performance, intestinal morphology and barrier function, and the functions of immune-related cytokines under NE in broilers. Results Infected group (PC) showed significant decrease in the average daily gain (ADG, p < 0.01) and increase in feed conversion ratio (FCR, p < 0.01) compared with C. butyricum (NECB1 and NECB2) through dietary supplement. Supplementation of C. butyricum (NECB1 and NECB2) restored the intestinal villus height, increased the crypt depth, and reduced the intestinal damage under NE. Furthermore, broilers infected with NE (PC) had higher serum IgA and endotoxin content, and after addition with C. butyricum (NECB1 and NECB2) returned to normal level. In addition, compared with PC, supplementation of C. butyricum (NECB1 and NECB2) restored intestinal barrier function-related genes (such as CLDN-1, CLDN-3, OCLN, MUC2, ZO-1, and CLDN5), cytokines (such as TNF-α, IL-10, IL-6, and TGFB1) and C. perfringens plc gene expression. Moreover, C. butyricum (NECB1 and NECB2) could restore the decrease in Gt (p < 0.01) and Isc caused by NE (PC). In addition, NECB2 reduced the upregulation of FD4 flux caused by NE infection (p < 0.01). Conclusion Dietary supplementation of C. butyricum into broilers with NE improved chicken growth performance, intestinal morphology, intestinal barrier function, and immune function. Notably, no statistical difference was observed with the addition of C. butyricum at different time points.
