With the rapid development of the livestock and poultry industry, the availability of feed resources in China has become a critical limiting factor, posing a significant challenge to the sustainable growth of animal husbandry. Black soldier fly (BSF) larvae are rich in protein, lipids, minerals, and trace elements and possess an essential amino acid profile comparable to that of fishmeal and soybean meal, which makes them a promising novel protein source for feed. This study aimed to investigate the effects of dietary BSF larvae protein supplementation on the growth performance, egg production, as well as meat and egg quality, blood biochemical parameters, and cecal microbiota diversity of Yunshang countryside chickens. The results showed that the inclusion of BSF larvae protein in the diet significantly reduced the feed-to-egg ratio and enhanced egg quality. Dietary supplementation with BSF larvae protein also effectively increased the abundance of dominant bacterial phyla and genera in the cecum, with the optimal inclusion level identified as 7.5%. Overall, the results demonstrate that BSF larvae can serve as a high-quality protein source in poultry production, thereby providing a scientific reference for the development and application of new feed resources and offering a theoretical basis for the utilization of BSF larvae as an alternative protein ingredient.
