摘要
本试验选择出生日期和体重接近的(德肉美×本地)断奶杂交羔羊组成试验组参加试验。结果表明,在本地5~7月的气候条件和各种管理因素确定的情况下,日粮粗蛋白水平对育肥羔羊增重的影响强度为9.31 kg,占作用总和的40.63%,是最主要的控制因素;代谢能影响强度为8.66 kg,占作用总和的37.78%,是第二控制因素。在日粮代谢能和粗蛋白质确定的情况下,粗饲料类型的影响强度为1.71kg,占作用总和的7.46%,处在从属地位。同时,全株玉米青贮的育肥效果明显优于其它粗饲料,而其它粗饲料之间无显著差异。
Fine hybrid lambs of similar birth date and weight was selected in the experiment.Results indicated that under local climate conditions during May to July and specific management,crude protein level influenced 9.31 kg of lamb weight,accounting for 40.63% of total effect,so it is main factor.Metabolizing energy influenced 8.66 kg,accounting for 37.78% of total effect,and it is second factor.At a certain level of metabolizing energy and crude protein,the types of crude feeds influenced 1.71 kg,accounts for 7.46% of total effect,so it is subordinate factor.But fattening effect of complete stool maize ensiling was obvious better than other crude feeds,and there were not significant difference among other crude feeds.
