Meat-type chickens have been bred for prioritizing energy partitioning to rapid gain and lean tissue growth, which required feed restriction to be commonly applied in the industry to optimize egg production. This thesis studied the effects of controlling energy intake on energy partitioning to...
The effects of broiler breeder dietary energy and protein during rearing and dietary energy level of lay diets on egg composition, offspring performance and carcass yield were evaluated. Pullets were fed a diet containing high ME (2,736 kcal/kg; HEREAR), or low ME (2,528 kcal/kg; LEREAR) combined...
Broiler breeders are feed restricted to control growth and increase the production of settable eggs. However, the consecutive need for the deposition and mobilization of nutrients, due the feeding and fasting cycles those birds are submitted to, is not a efficient process. Additionally, the less...
