Effects of breed and dietary nutrient density on the growth performance, blood metabolite, and genes expression of target of rapamycin (TOR) signalling pathway of female broiler chickens.

Abstract excerpt

This study was conducted to compare the effects of exchanged diets with identical energy level on characteristics of slow-growing (WENs Yellow-Feathered Chicken, WYFC) and fast-growing (White Recessive Rock Chicken, WRRC) female chickens. A total of 1450 WYFC and 1150 WRRC 1-day-old female hatchlings were used. A high-nutrient-density (HND) diet and a low-nutrient-density (LND) diet were formulated for three...
