本试验采用随机分组的设计方法，选用一冬龄草鱼180尾随机分成6组，每组3个重复，每重复10尾鱼，对照组不加酶，试验组中一组为溢多酶898A，另四组为不同厂家生产的饲用酶制剂，分别编号为E1、E2、E3、E4，5个试验组分别添加1‰的溢多酶898A、E1、E2、E3、E4进行对比试验，经50天饲养试验，结果数据经方差分析、多重比较表明：添加溢多酶898A组的相对生长率、饵料系数极显著优于其它各试验组和对照组（P＜0．01），肥满度显著高于其它各组（P＜0．05）。
In this study, a randomized grouping design method was used. One hundred and eighty-one winter-aged grass carp were randomly divided into 6 groups with 3 replicates in each group, 10 fish in each replicate, and no enzyme in the control group. The other four groups were feed enzyme preparations produced by different manufacturers, and the five experimental groups numbered E1, E2, E3 and E4 were respectively supplemented with 1 ‰ Polymyxin 898A, E1, E2, E3 and E4 for comparison test. 50 days feeding test, the results of the analysis of variance, multiple comparisons showed that: adding more enzyme Enzyme 898A relative growth rate, the feed efficiency was significantly better than the other test and control groups (P <0.01), fatness Significantly higher than other groups (P <0.05).
