摘要
选择体质状况相近的健康母犊牛14头,按试验要求随机分为试验组和对照组,每组7头,分别饲喂添加复合酶制剂和不添加酶制剂的日粮,比较分析专用复合酶制剂对犊牛的饲养效果。结果表明:试验组犊牛每头每天添加50g复合酶制剂,其日增重明显高于对照组(P<0.05);体质状况较对照组显著改善,腹泻率降低;经济效益十分明显。
14 female calves, similar in health, were divided randomly into 2 groups, which were the control group and treatment group. The control was fed with basic feed, and the treatment was fed with basic feed added with complex enzyme preparation. The results showed that the daily weight gain in experiment group by adding 50g complex enzyme preparation daily for every calf was higher than that in control group （P〈 0. 05）. The constitution condition of calves in experiment group was improved obviously, and the diarrhea ratio of its＇ was cut down. The economic returns was fairly obvious.
