Report on the effect of feeding alternative proteins on productive traits, physiological indicators, gut health and product quality and safety in chickens and turkeys

This deliverable summarizes the main results concerning the effects of the dietary substitution of soybean with alternative protein sources, namely microalgae meal, insect meal and single-cell proteins meal, on productive traits, physiological indicators, gut health and product quality and safety in broiler chickens and turkeys. In the different trials presented in this deliverable, the effect of feeding alternative protein sources was assessed through a multi-disciplinary approach that included the evaluation of growth performance, incidence and severity of foot-pad dermatitis as welfare indicator, breast meat quality traits, nutrient digestibility, plasma and cecal metabolome, and cecal microbiota.
