“…In this study, beta‐glucan had the ability to increase Lactobacillus and Bifidobacterium counts and to reduce Escherichia coli number. A similar effect was demonstrated on the beneficial microbiota in pigs fed mulberry ( Morus alba L.) leaf polysaccharides (Zhao et al, ). However, these data are in contrast to previous studies using 0.1 g/kg beta‐glucan from Saccharomyces cerevisae or 300 mg/kg laminarin derived from Laminaria digitata (Murphy et al, ; Zhou et al, ) , which all resulted in decreased number of Escherichia coli with no statistically significant effects on Lactobacillus and Bifidobacterium communities in their faecal microbiota.…”

Beta‐glucan is currently under consideration as an alternative to in‐feed antibiotics. The aim of the study was to investigate Agrobacterium sp. ZX09 beta‐glucan on intestinal morphology, cytokine concentration, mucin expression and microbial populations of weaning piglets. Pigs were randomly assigned to one of five dietary treatments supplemented with 0, 25, 50, 100 and 200 mg/kg beta‐glucan. Data showed an increase in ADG at the 100 mg/kg group (p = .03). A significant increase in villus height and reduction in crypt depth were fund in ileal tissue at the 100 mg/kg inclusion level (p < .05). Dietary supplementation of 100 mg/kg beta‐glucan enhanced IL‐10 concentration (p = .04) and gene expression of MUC1 and MUC2 (p < .05) in the jejunum. Dietary supplementation of 100 mg/kg beta‐glucan provoked the up‐regulation of Lactobacillus counts and down‐regulation of Escherichia coli counts in the caecum (p = .05). Data suggested that improved growth performance in response to beta‐glucan supplementation at 100 mg/kg in weaned piglets may be explained by the improved intestinal function.

“…A piglet with a score greater than 1 was regarded as having diarrhea. The diarrhea rate is expressed as the ratio between the number of pigs with diarrhea each day and the total number of pigs in each group ( Zhao et al, 2015 ). On d 14 and 28, one pig was randomly chosen from each pen (3 males and 3 females for each treatment) and blood samples were collected from the vena cava cranialis using tubes without anticoagulant.…”

The objective of this study was to investigate the effects of graded levels of isomaltooligosaccharides (IMO) on the performance, immune function and intestinal microflora and intestinal mucosal morphology of weaned pigs. In a 28-day experiment, one hundred eighty, twenty eight-day-old, crossbred (Duroc×Large White×Landrace), weaned pigs, with an initial body weight of 8.19±1.45 kg, were fed either an unsupplemented corn-soybean meal based diet or similar diets supplemented with 0.2%, 0.4%, 0.6%, or 0.8% IMO added at the expense of corn. Each treatment was replicated six times with six pigs (three barrows and three gilts) per pen. From day 0 to 14, weight gain was linearly increased (p<0.05), while gain:feed (p<0.05) was linearly improved and diarrhea rate (p = 0.05) linearly declined as the IMO level increased. On d 14, the level of the immunoglobulins IgA, IgM, and IgG in the serum of pigs were linearly increased (p<0.05) with increasing IMO supplementation. Interleukin-6 (IL-6) was linearly (p<0.05) and quadratically (p<0.05) decreased as IMO intake increased. From day 15 to 28, there was a trend for weight gain to be linearly increased, and IL-2 was linearly (p<0.05) increased as IMO supplementation increased on d 28. Over the entire experiment, weight gain was linearly increased (p<0.05), while gain:feed (p<0.05) was linearly improved and diarrhea rate (p<0.05) was linearly decreased as the IMO level increased. Supplementation with IMO had no effect on the intestinal microflora of pigs in the ileum and cecum of pigs, as well as the villus height and crypt depth in the ileum and jejunum (p>0.05). These results indicate that dietary inclusion of IMO increases weight gain, gain:feed and enhanced the immune status of pigs, and could be a valuable feed additive for use in weaned pigs, particularly during the period immediately after weaning.

This study was conducted to evaluate the effects of composite antimicrobial peptide (CAP) on growth performance and health status in weaned piglets. Over 28 days, 36 weaned piglets (body weight, 10.58 ± 0.99 kg) underwent three treatments: negative control (NC, basal diet), positive control (PC, basal diet + 20 mg/kg colistin sulphate + 50 mg/kg kitasamycin), and CAP treatment (CAP, basal diet with 400 mg/kg CAP). Average daily gain of piglets fed the CAP diet was greater (P < 0.05) than that of piglets fed the PC or NC diet during days 1-7, 8-14 and 15-21. Diarrhea rates of piglets fed the CAP or PC diet were lower (P < 0.05) than those of NC-fed piglets during days 1-7. Apparent total tract digestibility for dry matter and crude ash in CAP-fed piglets was greater (P < 0.05) than that of NC-fed piglets. In the CAP group, Lactobacillus and Bifidobacterium counts were greater (P < 0.05) and Escherichia coli counts were lower (P < 0.05) than numbers for the NC group. Our results indicate that dietary CAP had beneficial effects on growth performance and health status in weaned piglets.
