Hey Jos I got a 22 yr old mare (welsh/arab) in to breed, she had one foal about 10 yrs ago and had been turned out with a stallion until last year. She was not monitored, just turned out with 3 other mares and the stallion, the other mares got in foal and gave birth (not all got in foal every year). I bred her to Sparky by AI, did 3 shots of Oxytocin as a precaution. She is now 18 days in foal, I don't want to take any chances with her slipping it. How long should I keep her here on the farm before shipping her home which is 6 hours away?
Typically the best times to ship are before 3 days after ovulation or after about 60 days. You can push that second date up to perhaps 50 days, but what one is looking for is the formation of the endometrial cups and secondary CLs and also the initiation of placentation - the first happening around 36 days on and the second around 40 days on.
Having said all that, if the mare is not a bad traveller, you could probably move her safely any time unless it's really hot (I'm not sure where you're located) as the internal core temperature can have a negative impact during the embryonic stages if greatly elevated.
Thanks for the info Jos, Heat is a big issue, I'm in Gainesville, Fl. and the mare will need to go back to Atlanta, Ga. I had planned on keeping her 60 days but the vet that ultra sounded her said he preferred to wait 90 days. I had always heard 60 days was the magic number but that puts it to the beginning of August to ship her home which is the hottest time of the year. I feel lucky to have gotten her in foal and don't want to mess things up, will probably keep her until it starts to cool off a bit in September.
Yes, that's a good idea, will chat to the owner about that. It is an easy drive, I-75 over 95% of the way. Thanks
