Yes, just like other posters have said ovulation between 5-10. Found out my girls tend to ovulate closer to 10 than 5. If you are planning a litter that you really want my thought is, what's one more test? I typically use the progesterone numbers to back up my gut feeling. So glad I did because I had my first singleton last week if I had not know when she ovulated I wouldn't have felt as confident when I went to section on day 63 from ovulation.
Sometimes getting a bigger picture is better to piece together the details and if one more test is what it takes I would rather just do it.
I have done it before, but wont do it again. It's just more money to spend. We always wait 2-3 days after 5.0 to breed, and have been successful. Its more of a want to know number, because at that point either we are successful or not?!
I generally do one on the day of an insemination just to be sure she didn't stall. If I know what her numbers were that day, I can judge if I want to do a second cover.
