Calving rates after first insemination are often less than 50% in practice. Part of this low percentage might be explained by wrongly timed inseminations. Our hypothesis is that it is better to time insemination according to ovulation instead of according to behavioral estrus, but up to now it has not been possible to predict the time of ovulation in practice. So, to better time inseminations in practice, there is a need for predictors of ovulation time. Therefore, the relationship between various estrus characteristics and time of ovulation was studied to investigate whether these characteristics could predict time of ovulation. First standing heat was displayed 26.4±5.2h before ovulation. The increase in number of steps during estrus pred...
