摘要
将20 kg左右的80只小尾寒羊、80只湖羊随机分成4组,开展不同添加比例酶溢多对其日增重影响的试验研究。结果表明,日粮中额外添加10%的酶溢多时,小尾寒羊和湖羊的综合育肥效果最好,平均日增重分别为188.7、184.7 g;经济效益分别为115.5、107.3元/只。
80 small-tailed han sheep and 80 hu sheep were randomly divided into 4 groups,and the effects of different proportion of enzyme overflow on daily weight gain were studied.The results showed that the average daily gain was 188.7 and 184.7 g,and the economic benefit was 115.5 and 107.3 yuan per sheep,respectively.
