Abstract :In this study, it was aimed to determine some growth values from birth to 24 months of age in Holstein Friesian, Simmental and Brown-Swiss calves raised in Lalahan Livestock Research Institute. For this purpose, live weights and chest girth measurements of 88 calves born between 2018 and 2020 were regularly measured at 3-month intervals. Birth weight and chest girth values were found to be 40.43 kg and 75.05 cm in general, the effect of birth year and dam weight was significant insert ignore into journalissuearticles values(P<0.05);. While the birth weight of the calves was generally found as 6.31% of the live weight of their mothers, the effect of gender and dam weight was significant insert ignore into journalissuearticles values(P<0.05);. In the analysis of growth values after birth, the effect of breed was examined in all periods, the effect of sex in the period between 3-12 months and the pregnant status of the animal between 18-24 months. The live weights in these periods were 101.3, 169.6, 264.3, 347.1, 408.5, 478.3, 547.5 and 629.8 kg, respectively, the effect of breed was significant in all periods, and the effect of sex was significant at 9 and 12 months. The chest girth values were determined as 104.8, 128.3, 145.2, 161.7, 173.6, 186.2, 196.6 and 207.5 cm, respectively, breed differences were significant in all periods and sex differences were insignificant in all periods. The effect of whether the animal is pregnant or not at 18, 21 and 24 months was found to be insignificant in growth characteristics examined. As a result, the growth values obtained in this study with cultured breeds were found to be higher than the literature, and it was concluded that high-rate body weights could be estimated with chest girth measurements.
