Fecal Microbiota Transplantation Beneficially Regulates Intestinal Mucosal Autophagy and Alleviates Gut Barrier Injury.

Fecal microbiota transplantation (FMT) is one of the most effective ways to regulate the gut microbiota. Here, we investigated the effect of exogenous fecal microbiota on gut function from the perspective of analysis of the mucosal proteomes in a piglet model. A total of 289 differentially expressed proteins were annotated with 4,068 gene ontology (GO) function entries in the intestinal mucosa, and the levels of autophagy-related proteins in the forkhead box O (FoxO) signaling pathway were increased whereas the levels of proteins related to inflammation response were decreased in the recipient.

Exogenous Fecal Microbiota Transplantation from Local Adult Pigs to Crossbred Newborn Piglets.

This study was conducted to investigate the effect of exogenous fecal microbiota transplantation on gut bacterial community structure, gut barrier and growth performance in recipient piglets. Twelve litters of Duroc × Landrace × Yorkshire piglets of the same birth and parity were weighed and divided into two groups. One group (recipient piglets) was inoculated orally with fecal microbiota suspension of healthy adult Jinhua pigs daily from day 1 to day 11.

Effects of dietary fresh fermented soybean meal on growth performance, ammonia and particulate matter emissions, and nitrogen excretion in nursery piglets.

This study was conducted to investigate the effects of fresh fermented soybean meal (FSM) on the growth performance of nursery piglets, nitrogen excretion in feces, and the concentrations of ammonia (NH) and particulate matter (PM) in the piggery. A total of 472 nursery piglets (Landrace×Yorkshire, (16.3±0.

Changes of gut microbiota structure and morphology in weaned piglets treated with fresh fermented soybean meal.

This study investigated the effects of dietary fresh fermented soybean meal (FSM) on the intestinal microbiota and metabolites, bacterial enzyme activity and intestinal morphology of weaning piglets. A total of 64 weaned piglets were randomly allocated into two treatments. A corn-soybean-based diet was used as the control and other treatment was fed the same basal diet containing 15% fresh FSM.

Chitosan-Zn Chelate Downregulates TLR4-NF-κB Signal Pathway of Inflammatory Response and Cell Death-Associated Proteins Compared to Inorganic Zinc.

The study was conducted to investigate the effect of chitosan-zinc chelate (CS-Zn) on TLR4-NF-κB signaling pathway and cell death-associated proteins in a weanling pig model. A total of 90 weaned piglets were allotted to three dietary treatments (the dietary treatments were as follows: (1) experimental diet with supplemental ZnSO (150 mg Zn/kg diet), (2) experimental diet with supplemental CS-Zn (150 mg Zn/kg diet), and (3) experimental diet with a supplemental mixture of chitosan and ZnSO (150 mg/kg Zn; the content of chitosan was equal to CS-Zn, which is according to molar basis)). The feeding trial lasted 30 days.

The Expression of Zinc Transporters Changed in the Intestine of Weaned Pigs Exposed to Zinc Chitosan Chelate.

This study was conducted to investigate the effect of zinc chitosan chelate (CS-Zn) on zinc transporter expression and content of tissue zinc in weaned piglets. A total of 90 weaned pigs (Duroc × Landrace × Yorkshire) were randomly allocated to treatment groups with supplementation of 100 mg/kg zinc as ZnSO, 100 mg/kg zinc as mixture of ZnSO and chitosan, or 100 mg/kg zinc as CS-Zn, respectively. After 30 days of trial, 18 piglets (six pigs per treatment) were killed and the samples of duodenal mucosa were taken for analysis of zinc transporter mRNA expressions and protein abundance.

Changes in diarrhea, nutrients apparent digestibility, digestive enzyme activities of weaned piglets in response to chitosan-zinc chelate.

A total of 120 weanling barrows weighing 6.11 ± 0.20 kg were randomly allotted to four treatments with three replications (i.
