INFLUENCE OF FUNCTIONAL FEED ADDITIVES ON GUT MICROBIOME, HEALTH AND PRODUCTIVITY OF LAYING HENS: A REVIEW

Résumé

Functional feed additives significantly influence the composition and dynamics of the gut microbiome, with reciprocal effects on host health and productivity. The gut microbiome, therefore, plays a pivotal role in the health and productivity of laying hens. This review consolidates existing knowledge on the interplay between functional feed additives, gut microbiome, health and productivity of laying hens. It examines the influence of functional feed additives such as prebiotics and probiotics, organic acids, enzymes, vitamins, minerals, omega 3 fatty acids, and amino acids as interventions on gut microbiome composition, immune responses, and productivity. It equally highlights the potential of these tailored nutritional strategies to enhance egg production, promote sustainable practices, and advance the poultry industry.
