| 摘 要： | 研究L-肉碱对异育银鲫生长性能、血液生化指标和肌肉氨基酸组成的影响。L-肉碱在基础饵料中的添加水平分别为0、50、100、150,200、250mg／kg，饲养试验时间为40d。结果表明：L-肉碱可促进鲫鱼生长发育，200mg／kg组的鱼体的平均尾增重高于对照组13．23％（P〈0．05），饵料系数降低12．82％（P〈0．05）；异育银鲫血清中的生长激素（GH）含量提高，其中200mg／kg组高于对照组8．49％（P〈0．05），150mg／kg组的血清总胆固醇（CHO）和尿素氮（BUN）的含量分别降低10．85％、16．67％（P〈0．05），200rag／kg和250mg／kg组CHO和BUN降幅均达到极显著水平（P〈0．01）；各试验组鱼体肌肉氨基酸含量和组成均有不同程度改善。添加水平为200mg／kg时效果最好。

| Abstract: | Effects of L-carnitine on growth performance,biochemical indexes of blood and composition of amino acids in muscle of hybridized prussian carps were studied.The adding levels of L-carnitine in basal diets were 0,50,100,150,200 and 250 mg/kg and the test period was 40 d.the results indicated that L-carnitine could promote growth and development of the carps,the average weight gain per carp in Group of 200 mg/kg was 13.23% higher than that of Control Group(P<0.05),the feed conversion rate was reduced by12.82%... |
