Abstract
The aim of this study was to investigate the reproductive performance and the factors influencing reproductive performance of Holstein cattle reared in a private dairy cattle enterprise. Over 10 years, 480 records on reproduction were analysed with the least squares technique. Mean days open, services per conception, gestation period and calving interval were 114.5 ± 1.7 days, 2.01 ± 0.04, 278.7 ± 0.3 days and 394.9 ± 1.9 days, respectively. The effect of the lactation number on the gestation period was statistically significant (P < 0.001), whereas calving year and calving season had no significant effect on reproductive performance.
