The egg production, egg weight, feed intake and feed conversion was recorded every week, while the egg quality parameters such as shell thickness, shell breaking strength, Haugh unit, yolk colour and yolk to albumen ratio were measured every two weeks. Hen-day egg production, egg weight and feed conversion were not significantly different from the control at either dietary inclusion rates of 4 and 8% BSFLM, while yolk color scores were found to be significantly higher and progressively increased with increasing levels of BSFLM inclusion, possibly due to the presence of carotenoid in the larvae substrate. In comparison, 12% BSFLM inclusion significantly lowered hen-day egg production in comparison with control, egg weight, shell thickness, shell breaking strength and Haugh unit, suggesting that there is a threshold at which egg production and quality begin to be adversely affected. The results indicate that up to 50% inclusion of dietary soybean meal protein (8%) in layer diets could be replaced with BSFLM without compromising egg production or quality, and improved yolk pigmentation, but higher inclusion rates were detrimental to both egg production and internal and shell quality, possibly because of the higher proportion of dietary chitin and its effect on calcium utilization.</p> Aftab Shaukat Talat Bilal Yasoob Zabih Ullah Shah Copyright (c) 2026 Journal of Animal and Plant Research 2026-06-03 2026-06-03 3 2 1 5 10.66553/japr.2026.119
