Black soldier fly (BSF) larva is an attractive animal feed replacer due to its noticeable nutritional content. However, the conventional rearing method often resulted in BSF with undesirably high heavy metal residues that are harmful to animals. In this work, putrefied () leaves were employed as feed to rear BSF larvae. The resultant BSF prepupae were found to contain 43.5% protein and 16.7% fat, reflecting a comparable protein content and a 2-fold reduction in crude fat than those reared using conventional kitchen waste. Moreover, high quantities of arginine (25.4 g/kg dry matter basis (DM)), carnitine (32.9 g/kg DM), and short-chain fatty acids, including lauric (40.00%), palmitic (19.20%), and oleic (12.10%) acids, have also been noticed in the BSF prepupae. Furthermore, the BSF larvae have been recorded with 0.185 mg/kg chromium, 0.380 mg/kg selenium, and mercury below the detection limit, which is far lower than those reared using conventional kitchen and agricultural wastes (≈1.7 mg/kg chromium, 1.2 mg/kg selenium, and 0.2 mg/kg mercury). Overall, the study shows that the nutritional quality of BSF prepupae is extensively improved when using as their feed. The resultant BSF prepupae may serve as an alternative feed for animal rearing.
黑水虻幼虫因其显著的营养成分而成为一种有吸引力的动物饲料替代品。然而，传统的饲养方法常常导致黑水虻含有对动物有害的、重金属残留过高的问题。在这项研究中，使用腐叶作为饲料来饲养黑水虻幼虫。结果发现，由此产生的黑水虻预蛹含有43.5%的蛋白质和16.7%的脂肪，其蛋白质含量相当，粗脂肪含量比使用传统厨余垃圾饲养的减少了一半。此外，在黑水虻预蛹中还发现了大量的精氨酸（25.4克/千克干物质）、肉碱（32.9克/千克干物质）以及短链脂肪酸，包括月桂酸（40.00%）、棕榈酸（19.20%）和油酸（12.10%）。此外，记录显示黑水虻幼虫的铬含量为0.185毫克/千克，硒含量为0.380毫克/千克，汞含量低于检测限，这远低于使用传统厨余和农业废弃物饲养的（约1.7毫克/千克铬、1.2毫克/千克硒和0.2毫克/千克汞）。总体而言，该研究表明，以腐叶为饲料时，黑水虻预蛹的营养质量得到了显著改善。由此产生的黑水虻预蛹可作为动物饲养的替代饲料。
