Black soldier fly (BSF; ) has a high capacity for amino acids and fatty acid accumulation. This study was conducted to assess the effectiveness of tofu by-products, food waste, and vegetables for BSF growth and conversion efficiency. BSFs under tofu by-product treatments showed the greatest weight at d 12 and the harvest period. Moreover, BSF larval weight was greater in the food waste treatment compared with the vegetable treatment at d 12 and harvest. The larva yield result was greater in the vegetable treatment compared with the tofu by-product. The bioconversion rate was higher in the tofu by-product treatment compared with the food waste and vegetable treatments. The protein conversion rate and lipid conversion rate were the highest in the vegetable treatment. The protein yield and lipid yield were greatest in the tofu by-product treatment. The lauric acid content was increased in BSFs fed tofu by-products compared with the food waste treatment. The concentration of C16:1 was the highest in the tofu by-product treatment. The content of oleic acid and α-linolenic acid was higher in BSFs fed tofu by-products compared with the vegetable treatment. In conclusion, the tofu by-products show benefits for larval growth and nutrient accumulation, which can improve larval quality for livestock feed ingredients.
黑水虻（BSF）具有很高的氨基酸和脂肪酸积累能力。本研究旨在评估豆腐副产品、食物垃圾和蔬菜对黑水虻生长及转化效率的有效性。在豆腐副产品处理下的黑水虻在第12天和收获期体重最大。此外，在第12天和收获时，食物垃圾处理组的黑水虻幼虫体重比蔬菜处理组的更大。蔬菜处理组的幼虫产量结果比豆腐副产品处理组的更高。豆腐副产品处理组的生物转化率比食物垃圾和蔬菜处理组的更高。蔬菜处理组的蛋白质转化率和脂质转化率最高。豆腐副产品处理组的蛋白质产量和脂质产量最大。与食物垃圾处理组相比，喂食豆腐副产品的黑水虻中月桂酸含量增加。豆腐副产品处理组中C16:1的浓度最高。与蔬菜处理组相比，喂食豆腐副产品的黑水虻中油酸和α-亚麻酸的含量更高。总之，豆腐副产品对幼虫生长和营养积累有益，可提高作为牲畜饲料成分的幼虫质量。
