【摘要】:试验采用3×3因子正交试验设计,将270只1日龄织金白鹅随机分为9组,分别饲喂不同能量和粗蛋白水平日粮,代谢能(ME)水平分别为10.34、11.49和12.64 MJ/kg,粗蛋白(CP)水平分别为18%、20%和22%。结果表明:1~4周龄织金白鹅能量和蛋白质的需要量分别为ME=392.36BW~(~(0.75))+32.693ΔW和CP=1.69BW~(0.75)+0.4833ΔW;该阶段织金白鹅的能量(ME)和粗蛋白(CP)维持需要分别为392.49.KJ/W~(0.75)和1.75g/W~(0.75);日粮中ME和CP适宜需要量分别为11.29 MJ/kg和19.91%。
[Abstract]:In this experiment, 270 1-day-old Zhijin white geese were randomly divided into 9 groups by 3 脳 3 factor orthogonal design. The diets fed with different energy and crude protein levels were 10.34 mg / kg and 12.64 MJ / kg, respectively. The crude protein levels were 180.20% and 2222 MJ / kg, respectively. The results showed that the energy and protein requirements of the Wejin White Goose at the age of 1: 1 and 4 weeks were ME392.36 BWW (0.75) 32.693 螖 W and CP1. 69 BWW (0.75) 0.4833 螖 W, respectively, and the energy and crude protein (CP) maintenance requirements of the Wejin White Goose at this stage were 392.49 KJ / WN 0.75) and 1.75 g WN / R, respectively, and the appropriate dietary ME and CP were 11.29 MJ/kg and 19.91% respectively.
