摘要
根据白羽肉鸭常规饲料原料营养价值数据库和不同季节白羽肉鸭营养需要量的研究结果,利用研发的白羽肉鸭精准营养云系统优化出6套生长育肥期白羽肉鸭基础日粮配方。将540只21日龄樱桃谷鸭随机均分为6组,分别饲喂6种不同的试验饲粮,试验期21 d。35日龄时进行代谢试验,测定饲料养分消化率;42日龄屠宰,测定屠宰性能。根据生产性能、饲料消化率和屠宰性能综合分析,认为本试验设置的第3组试验日粮是22~42日龄白羽肉鸭的最优配方,其代谢能为12.10 MJ/kg,粗蛋白为16.14%。
According to the nutritional value database of conventional feed of white feather ducks and the nutritional requirements of white feather ducks in different seasons,six sets of basic diet formulations of white feather ducks during growth and fattening period were optimized by using the precision Nutrition cloud system of white feather ducks.A total of 54021-day-old Cherry Valley ducks were randomly divided into 6 groups and fed 6 different experimental diets for 21 days.Metabolic tests were performed at 35 days of age to determine the digestibility of feed nutrients,and slaughter was performed at 42 days of age to determine the slaughter performance.According to the comprehensive analysis of production performance,feed digestibility and slaughter performance,it was concluded that the third experimental diet set in this experiment was the optimal formula for white ducks aged 22~42 days,with metabolizable energy of 12.10 MJ/kg and crude protein of 16.14%.
