摘要
通过在日粮中添加不同水平多糖复合物(MCS),研究其对鲫鱼(CarassiusauratusL.)生长性能的影响。试验选用640条体重约为0.90g的鲫鱼,随机分为4组(对照组、0.25%、0.50%MCS组和1.00%MCS组)。试验期为8周。研究结果表明,添加0.25%和0.50%MCS可以显著提高试验鲫鱼终末均重、增重率和特定生长率(P<0.05);添加0.25%、0.50%和1.00%MCS,试验鲫鱼蛋白质利用效率显著提高(P<0.05);饵料系数有不同程度的降低,但差异不显著(P>0.05);存活率差异不显著(P>0.05)。表明在饲料中添加一定量的多糖复合物,对水产动物生长性能具有明显的促进作用,且以0.25%效果较佳。
The effects of the mixture of chitosan and saccharicterpenin （MCS） on growth performance of Carassius auratus L. were studied.Six hundred and forty fish with body weight about 0.9 g were allotted to four dietary treatments： the control group and three MCS-treated groups.MCS treated groups were supplemented with 0.25 % ,0.5 % and 1.00 % MCS in basal diets,respectively.Each group had four duplicates.The whole feeding period lasted for eight weeks.Results were showed as fellows ：The final average weight,weight gain rate and specific growth rate of fishes in 0.25 % and 0.50 % MCS group were significantly higher than those in the control group（P 〈 0.05） ;but there was no significant difference between 1.00 % MCS group and the control group （P 〉 0.05）.The protein emciency ratio of fishes in 0.25 % ,0.50 %, 1.00 % MCS group was obviously higher than that in the control group（P 〈 0.05）.Feeding efficiencies of three MCS-treated groups were all lower than that in control group,but no significant difference was found （P 〉 0.05）.There was also no significant difference in survival rate among four dietary treatments（P 〉 0.05）.The results indicated that MCS added in the diet could improve the growth of C.auratus L.significantly,and the optimal addition was 0.25 %.
