两种微生态制剂对草鱼消化相关酶活性的影响
Influence of Two Kinds of Microecologics on the Digestive Enzymes in Grass Carp
摘要
Abstract
Two kinds of microecologics (named M- I and M-II ) ,which were based on the Bacillus subtilis and had already been developed and applied in the practice, were selected to determine their influence on several digestive enzymes in grass carp. M- I was used to mix with the feeding and M-E was poured into the water of the ponds. Four groups were set in this study,including the control group,M- I group,M-II group,and the combination group of these two microecologics. After the usage of microecologics for 3 months, the amylase, protease and lipase of the livers and intestines were determined and compared with each other. The results indicated that M-II prepara tions , which mainly functioned on regulating the water quality, did not affect the three digestive enzymes in grass carp, while M-I preparations,which could promote digestion and growth of fishes, were found to greatly improve the enzyme activities. In addition,the mix usage of M- I and M- E were proved to play a role in both regulating the wa ter quality and promoting digestion, which would further promote the growth and reproduction of grass carp. There fore , it could be concluded that microecologics were benefit for the rapid and healthy growth of grass carp farmed in the ponds.关键词
