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

The experiment was conducted to investigate the effects of different mixed feed （proportion of chilled fresh trash fish and compound feed） on the growth, body composition and some physiological-biochemical index of Monopterus albus serum. Five treatments with formulated diet proportion were 0%, 25%, 50%, 75%, 90%. After 14 weeks, the experiment results showed that no significant differences in weight gain rate and survival rate between different treatments were observed; with the compound feed in the mixed feed increasing, the content of crude protein and crude fat increased first and then decreased; the contents of crude protein and crude fat were the lowest in the 90% treatment; there were no significant differences in ash content and moisture in each treatment; GOT, GPT, triglycerides, total cholesterol and blood glucose in the serums were significantly different in all treatments （P0.05）; compared with 0% treatment （complete chilled fresh trash fish feeding）, GOT and GPT in the serums were significantly reduced in the other treatments; GOT, GPT （50% treatment excluded）, total cholesterol in the serums of 75% treatment were the lowest of all treatments. Therefore, the conclusion demonstrated that it was appropriate to feed M. albus with proportion of 25% chilled fresh trash fish and 75% compound feed.
