Energy Restriction in Broiler Breeders Production Process
Due to broiler breeders'strong feed intake ability,it was necessary to control its body weight through restricted feeding dur-ing the production process to prevent excessive weight gain from leading to imbalanced reproductive system development during growth period and rapid decline in reproductive performance due to fat accumulation in later stages.This article mainly reviewed the energy re-striction in the production process of broiler breeders from the perspectives of animal nutrition and feed processing,as well as the feed-ing mode and routine.The main direction of animal nutrition was to reduce the concentration of nutrient content of feed,especially metabolic energy level.The main direction of feed processing was to use pellet feed to ensure balanced various nutrients intake.The main direction for feeding routine of broiler breeders was to change daily feeding mode and total feeding amount per week.During laying process of breeding hens,energy restriction was implemented based on the comprehensive egg production rate and daily feeding amount of each chicken,in order to fully utilize the egg production and reproductive performance of the broiler breeders.
