摘要 本文旨在研究非淀粉多糖酶对奥尼罗非鱼的生长及其抗菌力的影响。试验选用体重约60 g的奥尼罗非鱼(Oreochromis niloticus×O.aureus)560尾,随机分成4个处理组,每组7个重复,每重复20尾奥尼罗非鱼,分别投喂添加不同梯度的液体酶制剂(0、0.1、0.2和0.4 mL/kg的饲料)。结果表明:(1)非淀粉多糖酶对罗非鱼的特定生长率、饲料转化率等生产性能指标均有显著升高(P<0.05);(2)添加非淀粉多糖酶0.2 mL/kg和0.4 mL/kg显著提高了罗非鱼白细胞的吞噬活性(P<0.05)和血清的杀菌能力(P<0.01),试验组各组织溶菌酶活力也显著增加(P<0.05)。 A feeding trial was conducted to study the effect of non-starch polysaccharide (NSP) enzyme on the performance of hybrid tilapia Oreochromis niloticus ×O. aureus. Five hundred and sixty fish were randomly allotted to four groups with 7 replicates each and fed rations with different levels of NSP-enzyme (0, 0. 1, 0. 2 and 0.4 mL/kg feed). The results showed that 1) supplement of NSP-enzyme in the hybrid tilapia diet had significantly increased specific growth rate (SGR) and feed conversion rate (FCR) (P〈0.05); 2) the phagocytic function of tilapia leucocytes, serum bactericidal activities, and lysozyme activities of the hybrid tilapia tissues were improved significantly with the supplement of NSP-enzyme ( P〈0.05).
