不同饵料比对黄鳝生长及生理生化指标的影响

以冰鲜鱼与配合饲料5个不同比例饵料饲养黄鳝(Monopterus albus)14周,设定配合饲料所占比例分别为0％、25％、50％、75％、90％,研究不同饵料比处理对黄鳝生长、体成分及部分血清生理生化指标的影响.结果显示,各处理组黄鳝增重率、成活率均无显著差异(P＞0.05)；粗蛋白及粗脂肪含量随饵料中配合饲料比例增大呈先升高、后降低的趋势,且均以90％配合饲料组最低；而各组体灰分和水分差异不显著(P＞0.05)；各处理组黄鳝的血清谷草转氨酶(GOT)、谷丙转氨酶(GPT)、甘油三酯、总胆固醇及血糖有显著差异(P＜0.05)；与完全投喂冰鲜鱼(0％组)相比,其它各处理组血清GOT和GPT显著降低；75％配合饲料组血清GOT、GPT(50％组除外)、总胆固醇均为所有处理组最低；表明黄鳝投喂以25％冰鲜鱼和75％配合饲料的混合饵料为宜.

Effects of Different Fish Bait on Growth and Physiological-biochemical Index of Monopterus albus

Abstract: The experiment was conducted to investigate the effects of different feed (the proportion of ice fresh trash fish and formulated diet) on the growth and some physiological-biochemical index in Monopterus albus. Five treatments with formulated diet proportion were 0%, 25%, 50%, 75%, 90%. After 14 weeks experiment ,the results showed that no significant differences were found between the weight gain and survival rate; the content of crude protein and crude fat with the feed increased trend were increased firstly and then decreased, and both of them were the lowest in 90% feed group; but there were no significant different of ash and moisture in each group; All groups serum of GOT, GPT, triglycerides, total cholesterol and blood glucose were significantly different (P <0.05); Compared with completely fed ice fish (0% group) , the other groups serum of GOT and GPT activities were significantly reduced, and 75% formulated diet of serum GOT, GPT (50% group excluded), total cholesterol were the lowest in all groups. Therefore, the result showed that Monopterus albus was appropriate to fed with 25% ice fresh trash fish and 75% formulated diet.
