Abstract
This study was carried out at the poultry farms of animal production department, college of agriculture, University of Kirkuk from (3/3/2022 until 16/4/2022). The study aimed to determine the effect of adding different levels of arginine amino acid to the quail weight and carcass traits (breast, thigh, back, wings, heart, liver, gizzard). Live body weight was not significantly differing among the treatments, but the carcasses were significantly differing, it was higher in treatment 2 and 3 that fed with 5% and 10% arginine (106.78, 107.35) g. The Breast, thigh and wing weight also were significantly differing between the treatments, and it were higher in T2, and T3. But the back weight didn't significantly differ between the treatments. The giblets (heart, liver, and gizzard) were did not significantly differ between the treatments. It was concluded the adding arginine amino acid with 5 and 10% more the NRC requirements increase the weight of the most of carcass weight, and did not affect on the weight of heart, liver and gizzard.
