This study was conducted to determine the quality of given colostrum to calves born in three different dairy farms in Eregli district of Konya and to investigate the development of calves up to 60th day. A total of 71 calves were used in the study. 32 of them were male and 39 of them were female. The effect of sex, enterprises, number of birth and birth month were examined on the colostrum characteristics. Birth weight, 60th day weight, colostrum dry matter, colostrum specific gravity, serum IgG, IgM, IgA at birth and IgG, IgM and IgA values at 60th day averages were determined as 41.78 ± 4.30 kg, 79.57 ± 10.17, kg, 28.60 ± 2.33, 1067.40 ± 9.85 g / L, 0.03638 ± 0.005, 0.0801 ± 0.0041 and 0.0391 ± 0.0045; 0.0342 ± 0.0050, 0.0364 ± 0.0041 and 0.0181 ± 0.0045 mg / L, respectively. The effect of sex on birth weight was statistically significant at P<0.01 level, and the effect of the number of births and enterprises on birth weight was statistically significant at P<0.05 level. The effect of any factor on sixty-day weight was not statistically significant. The effect of birth number on colostrum DM was statistically significant at P<0.01 level. The effect of period factor was very important (P<0.01) for IgM and IgA, but it was insignificant for IgG.
