Abstract :In this study, it was aimed to investigate the relationship between birth weights and body measurements of Anatolian Black cattle and to develop linear regression equations to estimate calf birth weights. The animal material of this study, 108 Anatolian Black Cattle were used which were born in 2018. Those animals came from 21 different farms which are located in Osmansin village, Çamlıdere district of Ankara province. In study, birth weights insert ignore into journalissuearticles values(BW);, withers height insert ignore into journalissuearticles values(WH);, rump height insert ignore into journalissuearticles values(RH);, chest girth, insert ignore into journalissuearticles values(CG);, chest depth insert ignore into journalissuearticles values(CD);, body length insert ignore into journalissuearticles values(BL); and front wrist girth insert ignore into journalissuearticles values(FWG); were obtained in the order of; 14.451±0.397 kg, 57.775±0.347 cm, 59.843±0.382 cm, 53.510±0.517 cm, 24.137±0.281cm, 49.608±0.581 cm, 7.123±0.068 cm. The effect of calf gender was statistically significant only in FWG insert ignore into journalissuearticles values(P 0.05); effect BW, BL and FWG. The highest correlation was found between BW and CG insert ignore into journalissuearticles values(r=0.808); however, the lowest correlation was found between BW and FWG insert ignore into journalissuearticles values(r=0.467);. In addition, the highest correlation between body measurements was found between WH and RH with a value of 0.965. Regression analysis was performed between the chest girth and the live weight measurement, which is the measurement value that gives the highest correlation coefficient so that the live weight estimate can be made with the body weight parameters; BW = - 15.53 + 0.5577 CG insert ignore into journalissuearticles values(R2= 65.3%); formula was obtained.
