Abstract

This study investigated the effects of 3% (G3), 6% (G6), and 9% (G9) dietary defatted black soldier fly larvae (BSFL) meal on 288 Hy-Line Brown laying hens over 210 days. While egg production and weight showed no significant differences (p > 0.05), feed-to-egg ratios increased in higher inclusion groups (G6, G9) versus 0% control (G0) during later phases (p < 0.01). G6 exhibited enhanced eggshell strength versus G0 (p < 0.05), while G3 demonstrated thicker eggshells than all groups (p < 0.05). Serum analysis revealed G3 had superior total antioxidant capacity and lower lipid peroxidation versus G0 and G9 (p < 0.05), along with elevated gonadotropin-releasing hormone levels compared to G9 (p < 0.05). Intestinal morphology remained unaffected across treatments. The 3% BSFL inclusion optimally balanced eggshell quality and antioxidant status under isoenergetic-isoprotein conditions, supporting its viability as a sustainable protein source in poultry diets. Findings advocate BSFL meal as an eco-friendly feed alternative, with 3% identified as the most effective inclusion rate.

饲粮中添加脱脂黑虻幼虫对蛋鸡生产性能、蛋品质、血清生物标志物和肠道形态的影响

本试验研究了饲粮中添加3% （G3）、6% （G6）和9% （G9）脱脂黑虻幼虫（BSFL）对288只海兰褐蛋鸡210 d的影响。虽然产蛋量和产蛋量没有显著差异（p > 0.05），但在后期阶段，与0%对照组（p p p p p）相比，高包组（G6、G9）的料蛋比有所提高

期刊介绍： Frontiers in Veterinary Science is a global, peer-reviewed, Open Access journal that bridges animal and human health, brings a comparative approach to medical and surgical challenges, and advances innovative biotechnology and therapy. Veterinary research today is interdisciplinary, collaborative, and socially relevant, transforming how we understand and investigate animal health and disease. Fundamental research in emerging infectious diseases, predictive genomics, stem cell therapy, and translational modelling is grounded within the integrative social context of public and environmental health, wildlife conservation, novel biomarkers, societal well-being, and cutting-edge clinical practice and specialization. Frontiers in Veterinary Science brings a 21st-century approach—networked, collaborative, and Open Access—to communicate this progress and innovation to both the specialist and to the wider audience of readers in the field. Frontiers in Veterinary Science publishes articles on outstanding discoveries across a wide spectrum of translational, foundational, and clinical research. The journal''s mission is to bring all relevant veterinary sciences together on a single platform with the goal of improving animal and human health.
