研究外源核苷酸——5’-腺苷酸、5’-尿苷酸二钠、5’-胞苷酸二钠、5’-鸟苷酸二钠和5’-肌苷酸二钠对斑点叉尾鮰幼鱼生长性能、体成分和胃肠道形态的影响。结果表明:基础饲料中添加外源核苷酸没有显著提高斑点叉尾鮰幼鱼的增重率和特定生长率,但显著改善了鱼体的干物质和粗蛋白质含量,同时对胃肠道形态的发育具有显著地促进作用,其中以0.10%核苷酸混合物添加水平较佳。

The effects of the exogenous nucleotide levels （5＇ adenosine monophosphate, 5＇ disodium uridylate, 5＇ disodium cytidylate, 5＇ disodium guanylate and 5＇ disodiurn inosinate） on growth performance, body contents and gastrointestinal morphology of juvenile channel catfish （Ictalurus punctatus） were studied. The results showed that： the percent weight gain and specific growth rate were not significantly increased by the exogenous nucleotide supplement diet, but the dry matter and crude protein content were significantly increased,at the s...
