免疫增强剂和微生态制剂对凡纳滨对虾生长的影响

摘要

The effect of two kinds of Immunopotentiators (oligosaccharides ,the complexes of vitamins and small peptide)for the large-sized shrimp and EM (probiotics complex ) for the small size shrimp on the growth -promoting was studied .The results showed that the two kinds of Immunopotentiators could promote the growth on body length and weight for the large -sized shrimp in a certain extent , the growth-promoting effects of body weight was stronger than body length .EM also could promote the growth of body length and weight for the small shrimp to some extent ,and the growth stimulating effect increased with the concentration increasing .%以两种规格的凡纳滨对虾为试验对象，研究了2种免疫增强剂（低聚糖、维生素与小肽复合物）对大规格虾以及EM （微生态制剂复合物）对小规格虾的促生长作用。研究结果表明，两种免疫增强剂均能在一定程度上促进大规格凡纳滨对虾体长和体重的增长，对体重的促生长效果强于对体长的促生长效果。EM 也能在一定程度上促进凡纳滨对虾体长和体重的增长，而且随着浓度的增加促生长作用有所增强。
