Your ideal, from Foaling to Pregnant Mare

Postby Haylee2230 » Fri Mar 08, 2013 9:58 pm

Jos,

Can you answer this in the way you usually do it?

I would like to know your "ideal" schedule from the mare foaling (and not breeding on foal heat, I know you prefer to if everything is right) until 45days pregnant. (Including days you short cycle at and then the days you watch for estrus again, drugs used, days at what point every drug is used, days you u/s...etc)

Just would love to hear your ideal breeding :) Thanks!

It's going to depend upon a bunch of variables such as how the foaling went, whether there is post-foaling discharge, if there was damage associated with the foaling process, how the mare is looking condition-wise, and so on. In other words there is no "way we usually do it"!

The best I can offer is to perhaps present a scenario where a mare was not bred on her foal heat but was a good candidate for it except perhaps she ovulated too early. In other words no obvious issues.

In that case, we would short cycle the mare 6 days after foal heat ovulation (which would have been identified by use of ultrasound), giving her 1/10th of a "standard" dose of PGF2α two days in a row - on days 5 and 6 or 6 and 7 after the ovulation. We would then start ultrasounding her 3 days later if she had not showed signs of coming into estrus sooner (if she had a big follicle at the time of treatment with the PGF2α for example, we might ultrasound her 2 days after treatment). Upon entry to estrus, we would ultrasound and evaluate for fluid presence and treat that with oxytocin if necessary. Depending upon what form of semen was being used, she would be ultrasounded at appropriate time intervals and if using fresh or cooled semen bred before ovulation. If we were using frozen semen the timing of breeding would depend upon how many doses were available and being used. Four hours after breeding she would be treated with oxytocin, and that treatment may be repeated depending upon the mare and her condition.

We don't rely on doing certain things related to breeding on certain days after foaling, we rely on doing them at certain points after ovulation, having identified the ovulation. That is more reliable, as foal heat ovulation can take place anywhere - on the average - between 5 and 15 days after foaling. The risk of saying "do something on day X after foaling" is therefore obvious!

Pregnancy checks at 14 days and again before 28 days (typically at around 21/22 days).

I'm not sure that was really any help for you, but that's what we'd do in those circumstances! :)

That actually helped a lot! Sometimes I just need it all layed out in front of me! Thank you!
