摘要: Recent research to define a measure of chick quality has evaluated the effects incubation conditions, breeder age and genotype on progeny growth survival. Nutritional focused defining optimum concentration maternal dietary nutrients for growth, mortality immune status. There is requirement bring these two areas together better understand nutrition maximum quality. suggests that nutritional concentrations vitamin D are higher performance than egg production. Research also increased zinc, manganese selenium may benefit performance. Low energy density diets improved in young broiler breeders liveability offspring older breeders. evidence different genotypes have responses nutrient concentrations. Further quantify relationships between status relation warranted.
