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 (male/female ratio: 1/ 2) was fed diets having 17, 13 % crude protein (CP) without and with supplemental methionine, lysine and threonine (total of 3 treatments) during the 18 weeks. The low-protein diets (13 % CP) were equalized to control diet supplemented with methionine, lysine and threonine to increase their concentration to a level equivalent to control diet (% 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 (P>0.05). Decreasing dietary protein levels resulted in a significant (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 (13 %) without any supplemental essential amino acids and to get comparable result with performance of chukars fed diets containing conventional (17 %) protein levels.Keywords : Amino asit, Keklik, Nitrojen atılımı, Protein, Üreme
