氨基酸螯合盐对罗非鱼鲤鱼的促长效果

GROWTH-PROMOTING EFFECTS OF CHELATES OF AMINO ACIDS ON TILAPIA NILOTICA AND CYPRINUS CARPIO

在罗非鱼、鲤鱼饲料中 ,分别添加氨基酸螯合盐添加剂和无机盐添加剂 ,对罗非鱼、鲤鱼分别进行了对比喂养试验。结果表明 ,氨基酸螯合盐较无机盐具有显著促生长效果。罗非鱼添加螯合盐的两个试验组鱼的平均特定生长率分别比无机盐对照组提高 89.2 5 %和 79.6 1 % ;鲤鱼螯合盐试验组比对照组平均特定生长率提高 5 5 .0 0 % ,方差分析表明 。

Chelates of amino acids or inorganic salts were supplemented to the feed for Tilapia nilotica and Cyprinus carpio as additives. As compared with inorganic salts, chelates of amino acids greatly promoted the growth of the two fish species. The average specially designated growth rate was 89.25% and 79.61% higher in the two chelate treatment groups than in the inorganic salt treatment group for T. nilotica , respectively,and was 55.00% higher for C. carpio . Variance analysis showed that the difference between chelates of amino acids and inorganic salts in their growth promoting effects was highly significant.
