摘要
本试验设定日粮代谢能和粗蛋白质2个试验因子,每个因子设定3个处理水平,每个养羊户的试验母羊作为一个组参加试验。本试验的研究对象是处于妊娠初期的繁殖母羊,此期间胎儿的生长发育较慢,母羊需要保持10～20g/d左右的增重速度就能满足胎儿生长发育的需要,建议在生产中提供代谢能8.00Mj/kg、粗蛋白8.50%营养水平日粮。
The thick proteide testing that the supersession can draw originally setting up a daily ration 2 tests a factor,every factor sets up the ewe 3 handling level,every fostering experiment of sheep family participating in an experiment as a set.The object of study testing that originally is an ewe be in gravidity initial stage breeding,embryo＇s growth growth is slower during here,the ewe requires that the dynamiting speed keeping 10 ～ 20 g/days retinue is therefore likely to satisfy embryo growth growth need,the daily ration suggesting that 8.50% nutrition is horizontal in 8.00 Mj/kg,thick egg white producing middle providing the supersession energy.
