This experiment was conducted to evaluate the effects of caffeine and trans-cinnamaldehyde (TC) on growth performance, hematological parameters, stress hormones, immune response, and some blood parameters of broiler chickens. Three hundred fifty 1-d-old broiler chicks were randomly assigned to 7 dietary treatments (five pens/ treatment of 10 male broilers each) in a completely randomized desig...

newcastle disease is one of the most important diseases of poultry. it usually causes a great loss inpoultry industry and domestic village chickens. since domestic chickens in villages are free ranging for food,the chance of their contact with wild birds that may act as reservoirs is high. to determine the role ofdomestic chickens in the epizootiology of newcastle disease virus in villages of i...

This experiment was conducted to evaluate the effects of supplemental L-arginine (ARG) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. A total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. Treatment groups were designed as a normal-prote...
