Dietary collagen peptide‐chelated trace elements supplementation for breeder hens improves the intestinal health of chick offspring

Abstract

BackgroundDietary supplementation with trace elements zinc (Zn), iron (Fe), and manganese (Mn) could promote intestinal development and improve intestinal health. There are, however, few studies examining the possibility that maternal original Zn, Fe, and Mn could regulate the intestinal development and barrier function in the offspring. This study aimed to investigate how the intestinal growth and barrier function of breeder offspring were affected by collagen peptide chelated trace elements (PTE, Zn, Fe, Mn).ResultsPTE supplementation in the diet of breeder hens increased the concentrations of Zn, Fe, and Mn in egg yolk. Maternal PTE supplementation improved morphological parameters of the intestine (villi height, crypt depth, and villi height/crypt depth), and upregulated the mRNA expression level of leucine‐rich repeat‐containing G protein‐coupled receptor 5 (Lgr5) in the ileum of chick embryos. Furthermore, maternal PTE effect improved villi height/crypt depth of offspring at 1 and 14 days of age, and upregulated Lgr5, Claudin‐3, and E‐cadherin mRNA expression in the broiler ileum. Additionally, PTE treatment could enhance the intestinal microbial diversity of offspring. Maternal PTE supplementation increased the relative abundance of Clostridiales at the genus level and decreased the relative abundance of Enterococcus in newborn offspring. Moreover, maternal PTE supplementation ameliorated the elevated nuclear factor kappa B (NF‐κB), toll‐like receptor 4 (TLR4), and interleukin ‐1beta (IL‐1β) mRNA expression in the ileum of offspring caused by LPS challenge.ConclusionMaternal PTE supplementation could promote intestinal development, and enhance the intestinal barrier function of chicken offspring.This article is protected by copyright.

Maternal supplementation with mulberry-leaf flavonoids improves the development of skeletal muscle in the offspring of chickens

“…With the prohibition of growth-promoting antibiotics in feed, there is a growing interest to find new alternatives from the perspective of maternal nutrition ( Gao et al., 2023 ; Liu et al., 2024 ). Growing evidence has shown that the growth performance of offspring can be improved by maternal supplementation with plant flavonoids, including genistein, daizein and quercetin ( Amevor et al., 2022 ; Fan et al., 2018 ; Lv et al., 2018a , b ).…”
