蝇蛆蛋白粉对凡纳滨对虾生长的影响

设计了4种实验饲料(ABCD)并进行了8周饲养试验来评定添加蝇蛆粉对凡纳滨对虾生长性能的影响.以实用饲料D作为对照组,ABC是在D的基础上,分别以5%,10%和15%的蝇蛆粉替代鱼粉.养殖试验结束后,分别计算体长、全长和背甲宽等生长性能.实验结果显示,AB组凡纳滨对虾的生长性能与对照组差异不显著(P>0.05).C组与对照组差异极显著(P<0.01).结果表明,饲料中添加适量的蝇蛆蛋白粉对凡纳滨对虾有一定的促生长作用,可用适量的蝇蛆蛋白粉替代对虾配合饲料中的部分鱼粉.

Effects of housefly larva protein on growth of Litopenaeus vannamei

A 8-week feeding experiment was conducted to evaluate the effects of housefly larva protein on the growth of Litopenaeus vannamei.Four diets(ABCD)were formulated.D,which was a practical diet,was served as a control group.A,B and C groups were formulated respectively replacing 5%,10% and 15% fish meal with housefly larva meal.At the end of the feeding experiment, growth performances of body length,total length and width of carapace were calculated.The results of the feeding experiment showed that there were no significant differences in growth performance among A,B groups and D group(P > 0.05),but there were very significant differences in growth performance between C group and D group(P < 0.01).The results suggest that the dietary supplementation of pertain level of housefly larva meal can improve the growth performance in Litopenaeus vannamei,and the appropriate amount of housefly larva meal can be used to substitute partial fish meal in prawn manufactured feed.
