Low-protein diet boosts broiler breeder output

摘要

ALOW-crude protein diet for broiler breeders changes body composition during the rearing period, which positively affects hatch-ability during the first phase and egg production during the second phase of the laying period.Poultry scientist Rick van Emous of Wageningen University & Research in the Netherlands investigated the effect of two dietary protein levels — high and low — during rearing on feed intake, body composition at the end of the rearing period and reproductive performance of broiler breeder females. A total of 2,880 day-old Ross 308 broiler breeder female chicks were placed in 36 pens and were tracked until 60 weeks of age.
