Abstract Glucan has been studied as a potential alternative to antibiotics for animals in recent years. The aim of this study was to evaluate the effect of dietary glucan on growth performance and gut health of weaning piglets, which is a water-soluble extracellular ꞵ-glucan produced by Agrobacterium sp. ZX09. A total of 108 weaned piglets (21 d of age; 6.05 ± 0.36 kg) were randomly assigned (6 pens/diet; 18 piglets/pen) to 3 dietary treatments consisting of a basal diet (control group) or the basal diet supplemented with 20 ppm olaquindox or 200 ppm glucan for 14 days, respectively. The results showed that piglets fed with glucan had greater (P < 0.05) body weight and average daily gain than piglets in control group. Piglets fed with glucan or antibiotic had greater villus height to crypt depth ratio on duodenum compared with control group (P < 0.05). The mRNA expression of Claudin-1 on duodenum or ileum was higher (P < 0.05) in glucan group than that on the other groups. The mRNA expression of TLR4, MYD88 and NFκB on jejunum were lower (P < 0.05) in glucan or antibiotic group than those in control group. Dietary supplementation with glucan tended to increase the IL-10 and SIgA concentration on ileum (0.05 < P < 0.1). Dietary supplementation with glucan tended to increase the total antioxidant capacity on jejunum (P = 0.093). In conclusion, 200 ppm glucan or 20 ppm olaquindox can improve the growth performance of weaning piglets. The glucan may can accelerate the growth of weaned piglets by improving gut health. This research will provide guidance for the olaquindox alternative on growing piglets.

Abstract Antibiotics are commonly overused to reduce weaning stress that leads to economic loss in swine production. As potential substitutes of antibiotics, plant extracts have attracted the attention of researchers. However, one of the plant extracts, tannic acid (TA), has an adverse effect on the growth performance, palatability, and intestinal absorption in weaning piglets when used at a large amount. Thus, this study aimed to investigate the effects of a proper dose of microencapsulated TA on the growth performance, organ and intestinal development, intestinal morphology, intestinal nutrient transporters, and colonic microbiota in weaning piglets. Forty-five Duroc × [Landrace × Yorkshire] (initial body weight = 5.99 ± 0.13 kg, weaned days = 21 d) piglets were randomly divided into five treatment groups (n = 9) and raised in 14 d. The piglets in the control group were raised on a basal diet; the piglets in the antibiotic test group were raised on a basal diet with three antibiotics (375 mg/kg Chlortetracycline 20%, 500 mg/kg Enramycin 4%, 1,500 mg/kg Oxytetracycline calcium 20%); and the other three groups were raised on a basal diet with three doses of microencapsulated TA (TA1, 500 mg/kg; TA2, 1,000 mg/kg; TA3, 1,500 mg/kg). All the piglets were raised in the same environment and given the same amount of nutrients for 2 wk. The results showed that both TA1 and TA2 groups had no adverse effect on the growth performance, organ weight and intestinal growth, and the pH value of gastrointestinal content. TA2 treatment improved the duodenal morphology (P < 0.05), increased the gene expression level of solute carrier family 6, member 19 and solute carrier family 15, member 1 (P < 0.05) in the ileum, and modulated the colonic bacteria composition (P < 0.05), but inhibited the activity of maltase in the ileum (P < 0.05) and the jejunal gene expression level of solute carrier family 5, member 1 (P < 0.05). In conclusion, our study suggests that a dosage between 500 and 1,000 mg/kg of microencapsulated TA is safe to be included in the swine diet and that 1,000 mg/kg of microencapsulated TA has beneficial effects on intestinal morphology, intestinal nutrient transporter, and intestinal microbiota in weaning piglets. These findings provide new insights into suitable alternatives to antibiotics for improving growth performance and colonic microbiota.

AbstractThe present study was conducted to investigate effects of Bacillus subtilis on growth performance, serum parameters, digestive enzymes, intestinal morphology, and colonic microbiota in piglets. A total of 72 piglets were weighed and randomly allotted into three treatments (four replication pens per treatment with six piglets/pen) for a 28-day experiment. The dietary treatments were as follows: basal diet (control group, CTR), basal diet supplementation with antibiotic (antibiotic group, ABT), and basal diet supplementation with 0.1% Bacillus subtilis (probiotic group, PBT). The average daily gain of body weight increased in both the ABT and PBT groups, and dietary antibiotics decreased the feed:gain ratio (F:G), as compared to the CTR group (P < 0.05). Both ABT and PBT piglets had increased serum triglycerides and lipase, amylase, maltase activities and villus height:crypt depth ratio (V/C) in ileum (P < 0.05). The PBT group also showed an increase in serum glucose and villus height in the ileum (P < 0.05). Dietary antibiotics increased Lactobacillus johnsonii, as compared to the CTR group, but decreased bacterial diversity and increased Escherichia coli, as compared to the PBT group (P < 0.05). Piglets dietary with B. subtilis modulated the microbiota by increasing the abundance of Firmicutes (L. johnsonii, L. reuteri) and decreasing the abundance of E. coli, as compared to the control group (P < 0.05). These results indicate that dietary of B. subtilis improves growth performance and intestinal health and can be a promising alternative to antibiotics in piglets diet.
