摘要
将高邮鸭蛋用品系0日龄鸭360只,采用3×3因子设计了9个不同能量水平(11.70、11.90和12.12MJ/kg)、蛋白水平(18.0、19.0和20.0%)的日粮,分别饲喂9个处理组鸭,每个处理组4个重复,每个重复10只,进行28天的饲养试验,并结合屠宰试验进行高邮鸭蛋鸭育雏阶段日粮能量、蛋白需要水平的初步探讨,试验结果表明:在高邮鸭蛋用品系鸭0～28日龄的育雏期内,日粮能量水平为11.70MJ/kg和蛋白水平在18%左右,能更好的发挥高邮鸭的生长性能。
The study was undertaken to assess dietary. CP and ME concentrations for optimum growth performance and carcass characteristics of Gaoyou ducklings. In a 3×3 factorial arrangement,360 0-day-age Gaoyou ducklings were randomly assigned to experimental diets with 11.70,11.90 and 12.12 MJ/kg ME;each contained 18.0,19.0 and 20.0% CP,respectively, from 0 to 28 days of agel Each dietary treatment was replicated 4 times. The result showed that Gaoyou ducklings fed with a diet of ME 11.70 MJ/kg and CP 18% were better for growth performance and carcass characteristics from 0 to 28 days of age.
