Probiotic supplementation regulated swine growth performance, fecal odor reduction and carcass characteristics by modulating intestinal microbiome.

ABSTRACT:

Background

Using probiotics as a substitute for antibiotic growth promoters and reducing odor has received increasing attention in animal science. Despite the extensive investigation into the effects of probiotic administration on swine growth performance and odor reduction by short study durations, the analysis of carcass characteristics and potential mechanistic insights involving gut microbiota and downstream pathways is still few.

Methods

A total of 48 crossbred LYD [(Landrace x Yorkshire) x Duroc] piglets (equal numbers of males and females) were randomly assigned to one of four dietary treatments: control (CON), Lactobacillus kefiranofaciens M1 (M1), M1 + Bacillus amyloliquefaciens S20 (SA group) and M1 + S20 + Bacillus subtilis S14 (SAM group).
