| Abstract | ||
| The study's aim was to evaluate the effects of dietary zinc sources on carcass traits, mortality, cell-mediated immune response, physiological traits, and economic evaluation of broiler chickens. The chicks were randomly separated into 4 treatments. The dietary treatments were: the T1, as a control group, received the basal diet without zinc supplementation. The T2 was supplied with inorganic zinc oxide. The T3 was supplied with organic zinc-lysine. The T4 was supplied with a prepared nano zinc oxide (NZnO). T2, T3, and T4 were supplied by different zinc sources at a level of 40 mg Zn/kg diet. Our data stated that nano zinc oxide (T4) and zinc lysine (T3), 40 mg Zn/kg of diet, significantly recorded the highest carcass weight and breast muscle weight (P | ||
