Faecal microbiome sequences in relation to the egg-laying performance of hens using amplicon-based metagenomic association analysis

Abstract: Exploring the composition and structure of the faecal microbial community improves the understanding of the role of the gut microbiota in the gastrointestinal function and the egg-laying performance of hens. Therefore, detection of hen–microbial interactions can explore a new breeding marker for the selection of egg production due to the important role of the gut microbiome in the host’s metabolism and health. Recently, the gut microbiota has been recognised as a regulator of host performance, which has led to… Show more

“…This represents the first report by our team of a relative abundance of Fusobacteria > 1% ( Zhu et al, 2020a , b ). Fusobacteria were detected in Partridge Shank chickens under free-range breeding conditions, but not in chickens fed in cages ( Sun et al, 2018 ), while Elokil et al reported an abundance of about 0.011%–0.060% for Fusobacteria sequenced in laying chickens housed in individual cages inside an enclosed farm ( Elokil et al, 2020 ). These results suggest that Fusobacteria may be a normal component of the intestinal microbiota, even though some studies failed to detect its relative abundance.…”

“…For instance, the abundance of Lactobacillus, Bi dobacterium, Acinetobacter, Flavobacteriaceae, Lachnoclostridum and Rhodococcus was higher in the High egg-laying performance group in comparison with Low egg-laying performance group [9]. A 0.6% Lactobacillus supplement in the diet increased the egg production of feeding laying hens [9]. Therefore, the laying rate was signi cantly higher in the SY0.30 group than in the SS0.45 group, which may be due to the abundance Lactobacillus in the ileum.…”

“…It has been estimated that there is a signi cant positive correlation between the abundance of Lactobacillus and the laying rate, which is consistent with other results. For instance, the abundance of Lactobacillus, Bi dobacterium, Acinetobacter, Flavobacteriaceae, Lachnoclostridum and Rhodococcus was higher in the High egg-laying performance group in comparison with Low egg-laying performance group [9]. A 0.6% Lactobacillus supplement in the diet increased the egg production of feeding laying hens [9].…”

“…More recently, a metagenomic association study showed that the gut microbial communities of chickens with high egg production performance differ significantly from those of chickens with low egg production performance [28].…”
