家蝇幼虫营养成分价值的研究

目的获得畜禽粪便养殖家蝇生产蝇蛆动物蛋白的实验室数据,评价用蝇蛆代替鱼粉饲养蛋鸡的效果及经济效益.方法在相同的实验室饲养环境下,观察人工饲料、猪粪饲养的家蝇幼虫体内脂肪酸及微量元素含量的区别;用蝇蛆粉或鲜蛆代替鱼粉饲养蛋鸡,观察对蛋质的影响.结果用猪粪饲养的蝇蛆其体内所含的微量元素(Ca、Fe、Cu、Zn、Se)高于用人工饲料饲养的蝇蛆(P<0.05);用蝇蛆粉或鲜蛆代替鱼粉饲养蛋鸡,蛋内的脂肪酸及微量元素含量没有明显改变(P>0.05).结论用猪粪饲养家蝇可以生产出价廉、优质、富含微量元素的蝇蛆蛋白,而用蝇蛆代替鱼粉饲养蛋鸡不会影响鸡蛋的质量.

STUDY ON NUTRITION CONTENTS AND VALUE OF MUSCA DOMESTICA LARVAE

Objective To gain experimental data about breeding Musca domestica larvae by pig manure and to evaluate the effects and cost-benefit of feeding hens with larvae instead of fish powder. Methods The concentration of fatty acids and trace elements in the larvae bred with man-made fodder or pig manure were measured. The quality of eggs produced by hens fed with the larva powder or fresh larvae was investigated. Results The contents of trace elements (Ca,Fe,Cu,Zn,Se) of the larvae bred with pig manure were higher than those with man-made fodder(P<0.05). There were not significant differences of the contents of fatty acids and trace elements between the eggs produced by hens fed with the Musca domestica larva powder and fresh larvae respectively (P>0.05). Conclusion Breeding Musca domestica larvae with pig manure could produce good larva protein and reduce the expenses. The quality of the egg produced by the hens fed with larvae is as good as the quality of common eggs.
