This study investigated the effects of substituting bone meal with black soldier fly larvae (BSFL) in the feed of Ac chickens. A prospective randomized control design was employed on a total of 108 Ac chickens, which randomly divided into two experimental groups (EG1 and EG2) and one control group (CG) with equal number of chickens in each group. The chickens in CG were fed twice a day with 100% bone meal supplementation (feed inclusion rates of 12%), EG1 with 50% BSFL and 50% bone meal, and EG2 with 100% BSFL. The experiment started at 5 weeks of chickens' age and continued until 13 weeks of age. We found significant differences in average weight, with the EG2 exhibiting the highest weight at 738 g, followed by the EG1 at 736 g, and the CG at 603 g at 13 weeks of age. Chest circumference and body length were also significantly higher in the EG2 and EG1 compared to CG. The proportions of valuable meat portions, such as thigh meat and breast meat, were higher in the EG2 and EG1 compared to CG. Furthermore, the total amino acid content in the meat of Ac chickens was highest in the EG2 at 19.3%, while the CG had the lowest content at 18.8%. The essential amino acid content was also higher in EG1 and EG2 compared to CG. Substituting bone meal with BSFL in the feed of Ac chickens has positively influenced weight gain, body measurements, meat yield, and amino acid content.
