摘  要：
为研究不同饲养方式对沂蒙黑山羊生长的影响,选取最合适育肥的饲喂方法,于2018年8月选取体况相近的3月龄断奶沂蒙黑山羊羔羊60只,随机分为4组,每组3个重复,分别采用放牧+补饲、精粗饲料早晚分开饲喂、全混合日粮早晚两次饲喂及全混合日粮早晨一次饲喂4种饲喂方式进行试验,试验期60 d,15 d预试期。试验结果表明:舍饲沂蒙黑山羊的生长效果明显好于放牧+补饲;在舍饲中,饲喂全混合日粮要好于精粗饲料早晚分开饲喂,而全混合日粮早晚两次饲喂和早晨一次饲喂对沂蒙黑山羊生长影响不大。对于体尺体重指标,与体重相关性最大的是胸宽(r=0.963),其次是胸围和管围(r=0.638,0.591),同时发现体长和管围极显著相关(r=0.991)。从经济效益方面考虑,舍饲全混合日粮要高于放牧+补饲及精粗分开饲喂,同时相比之下,全混合日粮饲养早晨一次饲喂在保证沂蒙黑山羊育肥效果的同时可使饲喂更加方便及省时省力。

摘  要：
To study the effects of different feeding models on the fattening performance of Yimeng-black goats, and to select the most suitable feeding method, 60 Yimeng-black lambs which were weaned at 3 months of age and which had similar body conditions were randomly divided into 4 groups, with three replicates in each group, in August, 2018. The feeding models were: grazing and supplementary feed for Group 1, concentrate and roughage fed separately in the morning and evening for Group 2, totally mixed rations fed twice in the morning and evening for Group 3, totally mixed rations fed only once in the morning for Group 4. The whole experiment lasted for 60 days preceeded with a 15-day pre-trial period. The results showed that the growth of the lambs housed indoors was better than that of those of Group 1, and for the groups housed indoors, the growth of the lambs in the group fed with the totally mixed rations was better than that of those in Group 2, but there were no significant differences between Groups 3 and 4 in this regard. In terms of the body size and weight, the most significant correlation with the body weight was chest width(r=0.963), followed by the chest width and the chest circumference(r=0.638, and r=0.591). The body length and tube circumference were also significantly correlated(r=0.991). In general, the economic benefit in the group fed with the totally mixed rations was better than that in Groups 3 and 4. In contrast, the total mixed rations fed once in the morning could ensure the fattening effect and could make feeding more convenient, and therefore had more advantages.
