| 摘 要： | 研究了不同投喂频率对黄鳝(Monopterus albus)摄食率、特定生长率、饵料效率、体重分化、鱼体组成的影响。试验共设5组不同投喂频率(2、3、4、12次/d和24次/d),每组3个重复,试验持续30 d。结果显示:投喂频率4次/d组的摄食率显著高于其它各组(P<0.05);特定生长率有不同程度增高,4次/d组达到最高(P<0.05);饲料利用效率4次/d组显著高于2次/d组(P<0.05),与其它组无显著性差异(P>0.05);随着投喂频率增加,各试验组组内个体体重无显著差异(P>0.05),黄鳝的规格趋于整齐。试验各组黄鳝的鱼体成分无显著性差异(P>0.05);饵料蛋白质和能量的表观消化率,在4次/d时达到最高(P<0.05)。试验表明:黄鳝的生长受投喂频率的影响,每天投喂4次是黄鳝养殖的最佳投喂频率。

| Abstract: | Experiments were conducted to investigate the influence of feeding frequency on feeding rate,specific growth rate,feed efficiency,growth differentiation and body composition in a native fish,Monopterus albus.Five groups of the juveniles were fed to satiation including:two meals per day,three meals per day,four meals per day,twelve meals per day and twenty four meals per day for 30 days.The results showed that:the feeding rate and special growth rate increased significantly at four meals per day(P<0.05);and ... |
