ABSTRACT Recycling animal waste is crucial for the circular economy, promoting environmental and sustainability. This study aimed to assess the impact of shrimp waste added to broiler diets on growth performance, slaughter and carcass characteristics, intestinal morphology, bone traits, and fatty acids in the meat. In the study, 315 ROSS‐308 male broiler chicks were utilised as the animal subjects. The experiment consisted of five groups based on the timing and amount of shrimp (Penaeus vannamei) waste addition to their diet (Control [C], 1% added the first 11 days [1% FED], 1% added during fattening [1% DF], 2% added during the first 11 days [2% FED], 2% added during fattening [2% DF]). The differences in body weight, body weight gain, total feed intake and total feed conversion ratio, carcass parameters, relative internal organ weights, and fatty acids of thigh and breast meat among the groups were found to be statistically insignificant (p > 0.05). The addition of shrimp waste to the diet only significantly affected the VH/CD ratio in the jejunum, with the C group showing a lower ratio (p < 0.05). Adding shrimp waste to the diet only affected the seedor index of the femur among the characteristics of the leg bones, and an interaction between the period and the group was observed for this trait (p < 0.05). According to the results, up to 2% shrimp waste can be added to the diet without adversely affecting broiler performance, carcass quality, villus and bone properties, and fatty acid composition. The use of shrimp waste in feed can benefit the broiler industry and protect to environment.
