چکیده

the objective of the present study was to determine the effects of different levels of l-arginine in the diet on the growth performance, carcass traits, and blood parameters of female ross broiler chickens within their starter period. a number of, 192 day old female ross broiler chickens were fed with 4 dietary treatments in a completely randomized design, each dietary treatment had 4 replication. dietary treatments included 100, 153, 168 and 183% of digestible arginine, as based on the ross catalogue recommendation. the birds, were fed from day 1 to 10. on the 10th day of experiment, three chickens per replication were randomly selected, blood samples were collected from each, and then the birds were slaughtered to measure carcass traits and determine blood parameters. the results revealed that dietary arginine treatments significantly (p
