This study investigated the effects of Periplaneta americana residue (PAR) on the growth performance and gut health of laying hens during the prebreeding phase. Over 11 weeks, 450 one-month-old Nandan Yao chickens were allocated to six dietary groups,with PAR replacing 0%, 10%, 20%, 30%, 40%, or 50%. soybean meal. The results revealed no significant impact of PAR on growth performance (P > 0.05). However, PAR supplementation significantly elevated duodenal and jejunal immunoglobulin A (IgA), as well as ileal immunoglobulin M (IgM) and IgG levels (P < 0.05). While no overall significant differences were observed in the villus height (VH), width (VW), crypt depth (CD), or the villus crypt ratio (V/C) (P > 0.05), the ileal villus height and the villus crypt ratio increased specifically in certain groups (P < 0.05). Additionally, the ileal and jejunal pH decreased significantly with increasing PAR (P < 0.05), and the intestinal microbiota diversity remained stable. Transcriptomic analysis revealed the regulatory roles of PAR in RNA biosynthesis, DNA repair, the immune response, and metabolic pathways. Overall, PAR incorporation modestly enhanced the growth performance and intestinal health of laying hens. These findings support PAR as an effective soybean meal substitute in poultry diets, with a replacement ratio of 30-50%, de growth performance monstrating optimal efficacy. This approach not only alleviates pressure on protein resources but also provides a scientific framework for valorizing insect-derived waste in circular agriculture.
