Summary
This study evaluates Tenebrio molitor (yellow mealworm) larvae meal as a partial or full replacement for soybean meal in laying hen diets, assessing impacts on productive performance and egg quality traits. Using 36 Isa-Brown hens divided across four dietary treatment groups, the research contributes empirical data to the growing body of literature on insect-based feed alternatives in poultry systems. The findings are likely to inform the feasibility of substituting conventional protein sources with locally producible insect meal, with potential implications for sustainability and input cost reduction in poultry production.
UK applicability
Although conducted in Algeria, the findings are broadly applicable to UK poultry producers exploring alternative protein sources, particularly given UK and EU policy interest in reducing soybean import dependency and permitting insect meal in poultry feed; regulatory frameworks differ but the nutritional principles are transferable.
Key measures
Egg production rate (%); egg weight (g); feed intake (g/day); feed conversion ratio; shell thickness (mm); Haugh unit score; yolk colour score; albumen height (mm)
Outcomes reported
The study measured laying performance (egg production rate, feed intake, feed conversion ratio) and egg quality parameters (shell thickness, albumen height, Haugh units, yolk colour, egg weight) in hens fed diets incorporating Tenebrio molitor larvae meal at varying inclusion levels.
