昆虫源壳聚糖在鲫鱼饲料中适宜添加水平的研究

Study of proper supplementation level of chitosan from insect resource in the feed of crucian carp

  • 摘要: 将平均体重为25.21.7 g尾-1的225尾鲫鱼(Carasslius auratus)随机分为5个处理组,每个处理组3个重复,每组15尾。饲喂昆虫源壳聚糖5种不同添加水平(0%、0.25%、0.50%、0.75%和1.00%)的饲料,研究昆虫源壳聚糖在鲫鱼饲料中的适宜添加水平。结果表明,添加昆虫源壳聚糖不同程度提高了鲫鱼的相对增重率,显著降低了饵料系数(P0.05),0.50%壳聚糖添加水平组的生长性能最好。通过计算最佳相对增重率和饵料系数时的昆虫源壳聚糖添加水平以及结合试验结果,认为鲫鱼饲料中昆虫源壳聚糖的适宜添加水平为0.50%~0.60%。

     

    Abstract: The proper supplementation level of chitosan from insect resource in the feed of crucian carp (Carassius auratus) was investigated. Two hundred and twenty-five crucian carp with average weight 25.21.7 g were randomly divided into five treatments, each with three replicates, 15 fish per replicate. The test fish were fed five diets with different levels of insect chitosan (0%, 0.25%, 0.50%, 0.75% and 1.00%), respectively. Compared to 0% chitosan treatment, relative growth rates of other chitosan supplementation treatments were improved by addition of chitosan, and feed coefficients were significantly decreased (P0.05), the growth performance of 0.5% chitosan supplementation treatment was the best among all treatments. By calculating the optimal level of insect chitosan to achieve the best relative growth rate and feed coefficient and considering the results of present study, 0.50%~0.60% insect chitosan was recommended to supplement in the feed of crucian carp.
