Differences in the composition of plasma metabolites and intestinal flora of piglets with different weaning weights revealed by untargeted metabolomics and 16S rRNA gene sequencing.

Background: Piglets with different weaning body weights exhibit varying growth performance. This study explores the relationship between their plasma metabolites and gut microbiota to reveal differences in metabolic regulation and microbial composition.

Results: Plasma and colon content samples from piglets of different weaning weights were collected.

Effects of potassium diformate on growth performance, apparent digestibility of nutrients, serum biochemical indices, and intestinal microflora in Cherry Valley ducks.

This study was performed to investigate the effects of potassium diformate (KDF) on growth performance, apparent digestibility of nutrients, serum biochemical indices, and intestinal microflora of Cherry Valley ducks. In total, 144 female healthy 1-day-old Cherry Valley ducks were divided into 3 groups with 6 replicates per group and 8 ducks per replicate according to the principle of similar body weight. The control group was fed a basic diet.
