When do you give up trying?
We have a 15 yr old Trak/TB mare who was a simply lovely amateur packer in her day. We retired her at the end of her 12 yr old year (injury), and bred her in the spring of her 13 yr old year. She took the 2nd time, had an uneventful pregnancy, foaled out well, and was a fantastic mom. We bred her 2x that year after foaling, each time shipped AI, and did it just prior to her ovulating. Vet (very exp'd repro) said everything was perfect, and no real reason why she didn't take, but was willing to give the benefit of doubt to the semen, as it was from an older stallion (although motility looked very good when checked). So we lost last year, when she was 14.
This spring, we re-bred her to the same stallion we tried last year, and again, everything went perfectly, and she didn't take. We then switched to Silvio. Things didn't go quite so well this time, as the vet gave her a shot on Monday, and we were anticipating ovulation Wed/Thurs, and she didn't ovulate until the following Tuesday! She was inseminated 5x in expectation of ovulation, but did not take again (perhaps the follicle was infertile by the time she did finally ovulate).
We bred her again last week. She was cultured Tuesday, flushed Wed, bred Thursday, she ovulated a bit later Thursday, and vet said she did not retain any fluid, and everything looked perfect, and again there should be no reason why she wouldn't take.
Obviously, we're hoping that she took when she gets checked in a couple of weeks. However, if she didn't take, yet again, when do you give up? Do we give her another try in October? It doesn't bother me to have an early fall baby vs. a spring one. The problem is that she doesn't have any other job except to be a mom, and she is so good at it, and her foal is just lovely. But we can't keep spending thousands on her not catching, and she's certainly not getting any younger. Sigh. :(
