Özet

The bitch has maximum two oestrous cycles a year and due to its long cycle and difficulty in determining ovulation time, there are difficulties in deciding the optimal insemination time. As a result of this, low litter size is seen in artificially inseminated bitches (Badinand et al., 1993; England, 1998). GnRH hormone is used in cattle, mare, rabbit and the other species to induce ovulation and enhance fertility. In the present study, determination of the optimal Insemination time and regulation of the long duration (24-72 hours) ovulations in a short time period by administering a GnRH preparation and their effects on pregnancy rates and litter sizes were investigated.
