A study was carried out to determine the effect of dietary supplementation of 3000 mg kg–1 zinc oxide (ZnO) on the small intestinal morphology and populations of enterobacteriaceae, lactobacilli and clostridia in ileal digesta and feces of weaned pigs. At 17 d of age, 36 pigs from nine litters were fitted with simple T-cannulae at the distal ileum and after a 2-h post-surgery recovery returned to their sows. At 21 d of age, the pigs were weaned and housed in individual metabolism crates. Pigs were allocated to receive a standard starter diet supplemented with or without 3000 mg kg–1 of ZnO. Ileal digesta and fecal samples were collected immediately before weaning and then on days 2, 4, 7, 9, and 11 after weaning and were used to quantify enterobacteriaceae, lactobacilli and clostridial populations by colony enumeration on selective media. Pigs were euthanized following the final sampling, and 2 cm sections of tissue were collected from sites 25, 50 and 75% along the length of the small intestine for determination of mucosal thickness (MT), crypt depth (CD), villous height (VH) and villous width (VW). Zinc oxide supplementation altered the mucosal morphology of the small intestine. Mucosal thickness (P < 0.08) and VH (P < 0.05) were increased at sites 25 and 50% along the length of the small intestine by ZnO supplementation. Overall VW also increased (P < 0.01) with ZnO supplementation. Crypt depth decreased (P < 0.05) at 75% along the length of the small intestine with ZnO supplementation. The ratio of VH to CD was higher (P < 0.05) for ZnO-supplemented than for control-fed pigs at sites 25, 50 and 75% along the length of the small intestine. There was no effect (P > 0.05) of supplementary ZnO on bacterial populations in ileal digesta or feces. The present study indicates that supplementing ZnO in starter diets changes the epithelial morphology of the small intestine, which may affect nutrient digestion and absorption in newly weaned pigs.

Abstract Background : We investigated the gut microbiota in patients with non-alcoholic fatty liver disease (NAFLD) and its correlation with fibrosis and steatosis as reflected in the controlled attenuation parameter and transient elastography valuesMethods : A cross-sectional study was performed on 37 patients with NAFLD at Cipto Mangunkusumo National General Hospital from December 2018 to March 2019. The gut microbiota was investigated in fecal samples with 16S RNA sequencing using the next-generation sequencing platform MiSeq (Illumina).Results : NAFLD was more common in patients with metabolic syndrome. Firmicutes, Bacteroidetes, and Proteobacteria were the predominant phyla. Bacteroides was more dominant than Prevotella, contrary to the results in previous studies on normal populations in Indonesia. Microbiota dysbiosis was observed in most samples. The gastrointestinal microbiota diversity was significantly decreased in patients with NAFLD with high triglyceride levels and central obesity. The Firmicutes/Bacteroidetes ratio correlated with steatosis and obesity, whereas some other species in the lower taxonomy were mostly correlated with steatosis and obesity without fibrosis. Proteobacteria is the only phylum strongly correlated with fibrosis in patients with normal body mass index.Conclusions : The gut microbiota diversity was decreased in patients with NAFLD with high triglyceride levels and central obesity, and certain gut microbes were correlated with fibrosis and steatosis.

This study was conducted to investigate the effects of in ovo and post-hatching supplementation with L-Glutamine (Gln) on hatching characteristics, performance, small intestinal morphology, and muscle development of broilers. At day 18 of incubation, 960 fertilized eggs were allocated to four treatments with six replicates. Eggs were i) not injected (negative control) (NC), ii) subject to the standard incubation procedure (PG), iii) injected with 1 ml sterile solution with 0.9% salt (positive control) (PC), and iv) injected with 1% Gln solution (IG). On hatching, the SC chicks were fed with 1% Gln for seven days. The remaining chicks were fed a commercial starter feed. After hatching, there were six replicates of 28 birds in each treatment. Hatchability and yolk sac weight were lower and yolk-free chick weight (YFCW), whole gastrointestinal tract (GIT) and breast muscle weights were higher at hatching for chicks from the IG treatment. At 42 days old, feed conversation ratio (FCR) was lower in birds that had Gln added to their diet than for the other treatments. The FCR was also lower in IG birds than birds in the NC group. The GIT weight, villus height, villus width and crypt depth of the birds receiving dietary supplementation of Gln were greater than those of birds in PC and IG. Thus, in ovo injection of Gln improved hatching characteristics except for hatchability. Further, in ovo and dietary Gln administration reduced FCR by stimulating digestive system development.
