Abstract: The effects of different ratio of dead animals meat to fruit and vegetable waste on the growth performance of black soldier fly larvae were studied. The study found that the waste meat as a substrate had high nutritional value. It met the relevant safety standards of feed, showing the potential of resource utilization. Through experiments, it was also found that the waste meat to fruits and vegetables with a mass ratio of 3∶1 was optimal, which could significantly improve the weight per larvae, the conversion rate and the survival rate of feed worms, reaching 100 mg/piece, 22.0% and 80.9%, respectively. In addition, the crude protein content of the dried black soldier fly reared in this mixed ratio was as high as 40.64%, and the essential amino acid index (EAAI) reached 0.88, indicating that it was a good source of protein feed. Studies have also pointed out that leucine was the first limiting amino acid, and the second limiting amino acid was histidine or lysine, which was recommended to be supplemented in practical applications. The research results provide a scientific basis for the resource utilization and high-value utilization of dead animals meat, as well as improve the economic benefits of solid waste sanitary treatment plants.
