Abstract :An experiment was conducted to determine the influence of low-protein diets supplemented with amino acid con-centration on the performance, reproductive characteristics and nitrogen excretion in breeding chukar partridge. In the experiment, 72 breeding chukar partridge at 36 weeks of age insert ignore into journalissuearticles values(male/female ratio: 1/ 2); was fed diets having 17, 13 % crude protein insert ignore into journalissuearticles values(CP); without and with supplemental methionine, lysine and threonine insert ignore into journalissuearticles values(total of 3 treatments); during the 18 weeks. The low-protein diets insert ignore into journalissuearticles values(13 % CP); were equalized to control diet supplemented with methionine, lysine and threonine to increase their concentration to a level equivalent to control diet insert ignore into journalissuearticles values(% 17 CP);. Each of the experimental diets was fed four replicates with 6 chukars per replicate. Feed and water were continuously available and light was provid-ed for 16 hours per day. There were no significant differences among the treatment groups in average body weight changes, feed intake, egg production, egg weight, egg mass and percentage of fertility and hatchability insert ignore into journalissuearticles values(P>0.05);. Decreasing dietary protein levels resulted in a significant insert ignore into journalissuearticles values(P< 0.01); decrease in nitrogen excretion. The results of the current study indicate that it is possible to obtain performance of breeding chukar partridge fed with low-protein diet insert ignore into journalissuearticles values(13 %); without any supplemental essential amino acids and to get comparable result with performance of chukars fed diets containing conventional insert ignore into journalissuearticles values(17 %); protein levels.
