A master's thesis in the Department of Animal Production at the College of Agriculture at the University of Basrah discussed the effect of adding different levels of shrimp shell powder to the diet on the productive and physiological performance of broilers. The message of student Hala Daoud Salman and supervision of Prof. Khaled Jallab Credi, by adding different levels of shrimp shell powder to the diet and studying its effect on some productive traits (represented by weight, weight gain, quantity of feed consumed and food conversion efficiency), physiological parameters (represented by cellular blood characteristics and some stress indicators), bone characteristics and tissue gut characteristics of broilers. The thesis aims to identify the efficiency of shrimp shell powder as feed additives, by adding different levels of it to the diet and studying its effect on some productive traits. The thesis concluded that adding 5 grams of shrimp shells powder per kilogram of feed improved the productivity standards represented by high growth rates, improved food conversion efficiency, and an improvement in physiological parameters represented by cellular and biochemical blood characteristics. It also led to an improvement in the birds’ immune status and antioxidant status. In the tissue of the intestines of birds.
