gut metagenome

This study aims to explore the impact of intestinal microbiota on feather coverage in laying hens by measuring the gut microbes of individuals with high and low feather coverage, with the core goal of improving laying hen welfare. Feather loss is a common problem in laying hen farming, which not only affects the birds' thermoregulation and disease resistance but also reflects their physiological stress and welfare status. By analyzing the differences in intestinal microbial composition and function between the two groups, the research seeks to identify specific microbial communities or metabolic pathways that may be associated with feather health. The findings are of great relevance as they could reveal the potential of modulating gut microbiota through dietary interventions or probiotic supplementation to promote feather growth and improve the overall welfare of laying hens, providing a new scientific basis for sustainable and humane poultry farming practices.
