On-top arginine supplementation during lactation affects milk composition, performance, and intestinal bacterial and viral microbial community of sows and their piglets.

ABSTRACT: Early gut microbiome colonization is crucial for gut physiology, immunity, and growth. It is influenced by factors like the maternal microbiome, which can be modified through diet, including amino acids (AAs) supplementation. Among AAs, arginine (Arg) is known to play a key role in lactating sows, which has attracted increased interest recently. The aim of this study was to investigate whether dietary supplementation of lactating sows with on-top Arg (22 g/d/sow) could influence the productive performance and milk of sows and their litters and their gut microbial community, including both viruses and bacteria. Thirty-two sows were divided into two groups balanced for parity and body weight: 1) control (CO) (fed a corn-based diet) and 2) CO + 22.5 g/d/sow of on-top Arg (ARG). Diets were fed
