Digestibility and transcriptomic profiling of kidney, pancreas, follicle, and uterus in laying hens supplemented with phytogenic feed additive.

ABSTRACT: Phytogenic feed additives in poultry demonstrate phenotypic improvements and potentially possess humoral significance for organ systems involved in egg production, digestion, and excretion, warranting further investigation into their mechanisms of action. These additives contain a wide array of active ingredients with antimicrobial, immunomodulatory, and antioxidant properties, positioning them as a promising alternative to in-feed antibiotics for enhancing poultry performance and welfare. This study investigates how a phytogenic feed supplement based mainly on essential oils of thyme and star anise with quillaja bark influences reproductive and nutrient-utilizing tissues and nutrient bioavailability in laying hens. A four-week trial with Lohmann Brown hens aged 68 weeks was conducted usin
