| Abstract | Feed costs currently account for more than 50% of the total production cost of house crickets, highlighting the need to identify alternative protein sources that can partially replace soybean meal. This study aimed to evaluate the potential of black soldier fly larvae (BSFL; Hermetia illucens) as an alternative protein source for replacing soybean meal in diets for the house cricket (Acheta domesticus). A completely randomized design (CRD) with four dietary treatments was employed, consisting of a commercial diet, a soybean meal-based control diet, and experimental diets in which soybean meal was replaced with BSFL at inclusion levels of 0%, 5%, and 10%. The effects of the dietary treatments on growth performance, productive Index, body size, and nutritional composition of house crickets were evaluated. The results showed that dietary BSFL inclusion had no significant effect on body weight gain of house crickets (P>0.05). However, supplementation with 5% BSFL resulted in the most favorable feed conversion ratio (FCR = 1.31) and the lowest feed intake (P<0.01). In addition, BSFL supplementation increased body width and tended to increase the proportion of large-sized crickets. In contrast, increasing the BSFL inclusion level to 10% reduced both survival rate and egg production. Regarding nutritional composition, crude fat content of the crickets increased with increasing BSFL inclusion, whereas crude protein content showed a decreasing trend. In conclusion, BSFL can serve as a promising alternative protein source to partially replace soybean meal in house cricket diets. An inclusion level of 5% was found to be optimal, as it improved feed utilization efficiency without adversely affecting growth performance and may contribute to reducing feed costs. Nevertheless, higher BSFL inclusion levels may negatively affect survival and productive Index; therefore, the inclusion level should be carefully optimized. |
