Abstract :In this research, 14 Akkaraman lambs were fattened after weaning at the 2.5 month age and then slaughtered. Fat-tening period constituted three months. Direct and indirect relationships between body measurements insert ignore into journalissuearticles values(live weight insert ignore into journalissuearticles values(X1);, wither heights insert ignore into journalissuearticles values(X2);, hearth girth insert ignore into journalissuearticles values(X3);, chest depth insert ignore into journalissuearticles values(X4);, leg girth insert ignore into journalissuearticles values(X5); and body length insert ignore into journalissuearticles values(X6);); taken at the beginning of fattening period and cold carcass weight insert ignore into journalissuearticles values(Y); in Akkaraman lambs were determined by path analysis. The path coeffi-cients related to direct effects of each variables on estimated variable were determined as -0.1913 for X1, 0.6035 for X2, 0.7921 for X3, 0.1792 for X4, 0.3694 for X5, -0.8731 for X6 respectively. The determination coefficient insert ignore into journalissuearticles values(R2); was found as 80.6. It has been determined that the factors which have the highest effects on the cold carcass weight are the heart girth, body weight and wither heights. According to these results, it was stated that hearth girth, body length and wither heights could be used as indirect selection criteria for the selection of cold carcass weight and the effectiveness of fattening could be increased by taking into consideration of these features.
