Unfortunately you cannot time breeding with taking the temperature.
There are a few different ways to successfully breed. These include 1) breeding on days 7, 9, and 11 (day 1 being the first day she bled), 2) having a vaginal smear checked by your veterinarian on these days (they look at the cells to determinewhen ovulation will be occurring) and 3) having her progesterone checked around day 6-7-8. The progesterone will surge right before ovulation
Make sure she has been tested for Brucellosis (this can cause infertility) and had her thyroid checked (a low thyroid can interfere with fertility)
