This study evaluated the productivity, nutritional composition, amino acid profile, fatty acid profile and presence of spp. of housefly larva meal reared on domestic animal manure. A study was conducted to produce larva on three types of manure in a controlled environment located at 3200 mASL. Adult flies used as brood stock were reared in advance to avoid contamination with pathogenic germs and were fed sugar syrup and pasteurized milk to promote oviposition. Data were analyzed by ANOVA, the Kruskal-Wallis test and descriptive statistics, using confidence intervals. The results indicate that the type of organic substrate had an effect on the time of development, weight, size and percentage mortality of larva, being higher in a mixture of swine manure and poultry manure. Regarding nutritional composition, it was determined that larva meals contain 56.5% crude protein, 13.07% fat, 12.03% carbohydrates, 10.93% ash and 6.77% crude fiber. The most abundant fatty acids are palmitic acid with 29.34%, palmitoleic acid with 21.65% and oleic acid with 26.53%. An adequate balance of amino acids was determined, highlighting among them the content of arginine and threonine within the essential amino acids. House fly larva meals contain an adequate balance of nutrients and can be used as an ingredient for animal feed formulation. However, their use in animals should be further evaluated in future studies to assess their viability, absorption, bioavailability, and potential allergic reactions.
本研究评估了以家畜粪便饲养的家蝇幼虫粉的生产率、营养成分、氨基酸谱、脂肪酸谱以及特定种类的存在情况。在海拔3200米的可控环境中，开展了一项利用三种类型粪便生产幼虫的研究。用作亲鱼的成年苍蝇提前饲养，以避免被病原菌污染，并喂食糖浆和巴氏杀菌牛奶以促进产卵。使用置信区间，通过方差分析、克鲁斯卡尔 - 沃利斯检验和描述性统计对数据进行分析。结果表明，有机底物类型对幼虫的发育时间、体重、大小和死亡率有影响，在猪粪和家禽粪便的混合物中更高。关于营养成分，确定幼虫粉含有56.5%的粗蛋白、13.07%的脂肪、12.03%的碳水化合物、10.93%的灰分和6.77%的粗纤维。最丰富的脂肪酸是棕榈酸（29.34%）、棕榈油酸（21.65%）和油酸（26.53%）。确定了氨基酸的适当平衡，其中必需氨基酸中的精氨酸和苏氨酸含量突出。家蝇幼虫粉含有营养成分的适当平衡，可作为动物饲料配方的一种成分。然而，其在动物中的使用应在未来研究中进一步评估，以评估其可行性、吸收、生物利用度和潜在的过敏反应。
