摘　　要：本文探讨饲喂玉米青贮后育肥期疆岳驴体重的变化,为玉米青贮科学使用提供参考方法。选取6~12月龄体重(95.66 kg±20.69 kg)和体况良好的疆岳驴育成驴52头,饲喂玉米青贮占粗饲料比例的50%饲粮。试验期73 d,前12 d为预试期,后61 d为正式期。探讨饲喂同一青贮日粮对不同月龄育成驴体重的变化规律。结论显示6月龄至7月龄和7月龄至8月龄的育肥驴体重增长显著高于其余月龄(P<0.05)。to investigate the changes of body weight of jiangyue donkey after feeding corn silage, and to provide a reference method for the scientific use of corn silage.Fifty-two Jiangyue donkeys aged from 6 to 12months with body weight(95.66 kg±20.69 kg)and good body condition were selected and fed a 50% corn silage diet. The experiment lasted for 73 days, with the first 12 days as the pre-trial period and the last 61days as the formal period. To investigate the change of body weight of donkeys at different age by feeding the same silage diet.The weight gain of fattening donkeys at 6-7 months and 7-8 months was significantly higher than that of other months(P<0.05). The diet with 50% roughage as silage had a significant effect on weight gain of donkeys aged 6-8 months.
