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 (BW), withers height (WH), rump height (RH), chest girth, (CG), chest depth (CD), body length (BL) and front wrist girth (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 (P<0.05), but not statistically significant in other characteristics. The effect of age maternal WH, RH, CG and CD values were significant (P<0.05), on the other hand, there is no significant (P>0.05) effect BW, BL and FWG. The highest correlation was found between BW and CG (r=0.808) however, the lowest correlation was found between BW and FWG (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 (R2= 65.3%) formula was obtained.
