Effects of Dietary Sterol-Enriched Yeast Hydrolysate on Ovar-ian Development, Reproductive Endocrine Status, Im-mune-Inflammatory Responses, Antioxidant Indices, and Egg Quality in Late-Laying Yellow-Feathered Broiler Breeder Hens

Description

The present study investigated the effects of graded dietary supplementation with sterol-enriched yeast hydrolysate (SYH) on reproductive performance, egg quality, ovarian development, reproductive endocrine status, immune-inflammatory responses, antioxidant status, and ovarian gene expression in late-laying yellow-feathered broiler breeder hens. A total of 720 55-week-old hens were assigned to four dietary treatments containing 0, 0.2, 0.5, or 0.8 g/kg SYH and were evaluated over a six-week feeding period.
