摘要
目的 :分析猪粪饲养家蝇 (Muscadomestica)幼虫的营养成分。方法 :引种野生家蝇 ,用猪粪饲养幼虫 ,收获 3期老熟幼虫 ,测定粗蛋白、粗脂肪、氨基酸和脂肪酸构成及微量元素含量 ,用粮食与农业组织 世界卫生组织 (FAO WHO)提出的参考蛋白模式评价 ,并与麦麸饲养的幼虫及鱼粉比较。结果 :每公斤猪粪平均可产(0 13± 0 0 4)～ (0 2 0± 0 12 )kg鲜蛆 ,鲜蛆烘干比为 1∶0 31± 0 12 ,粗蛋白 42 36 %～ 5 2 33 % ,必须氨基酸含量占总氨基酸的 45 10 % (E % ) ,必须氨基酸与非必需氨基酸总量的比值 (E/N)为 0 82 ,E % /T为 3 0 1,脂肪酸含量为 13 73 %～ 16 83 % ,油酸、亚油酸及亚麻酸等必需脂肪酸分别为 36 99% ,7 6 1%和 0 35 % ,Fe 2 91 5mg/kg ,Cu 87 5 5mg/kg ,Zn 2 46 8mg/kg ,Mn 2 49 45mg/kg ,比麦麸饲养幼虫更接近参考蛋白模式 ,营养价值优于鱼粉。结论 :猪粪饲养的家蝇幼虫比麦麸饲养的幼虫更接近参考蛋白模式 。
Objective:To evaluate the nutritional value of the housefly larva (Musca domestica) fed with pig manure. Methods: The composition of the protein, fat, amino acids, and trace elements of the larva was studied according to the protein reference modal of FAO WHO, with controls of fish meal and the larva fed with wheat bran. Results: 1?kg pig manure could produce (0.13±0.04)-(0.20±0.12)kg fresh larva,1kg fresh larva could make (0.31±0.12)?kg larva powder. The crud protein was 42.36%-52.33%, the essential amino acids(E%) account for 45.57%, E/N (nonessential amino acids)0.83, E%/T(T=3)3.04. The fat was 13.73%-16.83%, among which, the oleic acid, linolic acid and linolenic acid(essential fatty acids) were 36.99%,7 61% and 0 35% respectively. Fe was 291 5?mg/kg, Cu 87.55 mg/kg, Zn 246.8 mg/kg, Mn249 45 mg/kg. The nutritional value of the larva fed with pig manure was closer to the reference modal than with wheat bran and better than fish meal. Conclusion: The nutritional value of the larva fed with pig manure was as good as with wheat bran, and pig manure could be used to feed the housefly larva and produce excellent animal protein.
