试验将360尾体质量40g左右的鲤鱼,随机分为9组,采用U8(82)拟水平2次均匀试验设计研究了溢多酶(898-A)和溢康素-Ⅱ对鲤鱼生长性能的最适添加水平。结果表明,溢多酶(898-A)和溢康素-Ⅱ均能明显提高鲤鱼的存活率(P<0.05);单独添加使用,溢多酶(898-A)在0.116%～0.131%水平范围内,溢康素-Ⅱ在0.141%～0.183%水平范围内,可提高鲤鱼生长性能,使鲤鱼生长性能达到最佳;按照溢康素-Ⅱ0.074%～0.089%,溢多酶(898-A)0.055%～0.063%添加水平范围内结合使用,可提高鲤鱼生长性能,使鲤鱼生长性能达到最佳的水平。
The carp with 360 body weight of 40 g was randomly divided into 9 groups. U8 (82) was used to test the growth performance of common carp (898-A) and sp ecophen-Ⅱ The best level to add. The results showed that both Polyunsaturated (898-A) and eclampsin-Ⅱ significantly increased the survival rate of carp (P <0.05) In the range of 0.141% ~ 0.183%, ecotoneⅡ could improve the growth performance of carps and make the growth performance of carp reach the best. According to ecopractic-Ⅱ0.074% ~ 0.089% -A) in the range of 0.055% -0.063% can improve the growth performance of carps and make the growth performance of carps reach the best level.
