发酵饲料等其它蛋白源替代部分鱼粉对异育银鲫鱼种生产性能的影响研究

Effect of Fermented Feed and Other Protein Resources as a Substitute for Partial Fish Meal on the Performance of Allogynogentic Crucian Fingerlings

均重为15.0 g左右的240尾异育银鲫鱼种随机被分为4个组,即Ⅰ、Ⅱ、Ⅲ和Ⅳ组,每组3个平行(3个水族箱,规格100 cm×80 cm×60 cm),饲养60 d。Ⅰ组为对照组,饲喂基础日粮,其余3个组为试验组。设计发酵饲料按不同比例替代鱼粉的4个配方,研究发酵饲料替代部分鱼粉对异育银鲫鱼种生产性能的影响。结果表明:Ⅱ组的配方可以替代Ⅰ组的配方,且每1 t配合饲料节省83.50元。

240 allogynogentic crucian fingerlings with average weight of 15.0 g were divided randomly into four groups, namely Group Ⅰ, Group Ⅱ , Group Ill and Group IV; three aquatic animal boxes for each group （specification 100 cm ×60 cm × 80 cm） for breeding 60 d. Group Ⅰ was the control group fed on basic ration and other three groups were experiment groups. Four formulas of fermented feed were designed as substitute for fish meal in different proportions to study the production performance of allogynogentic crucian fingerlings. The results showed that the Group Ⅱ formula with 6% fermented feed and 4% corn protein flour could substitute Group Ⅰ formula with 11% fish meal, and RMB 83.50 could be saved per ton compound feed.
