He did say that the pH of some horses just didn’t mesh and you would have to change studs. We probably will it the shot doesn’t work. I know she can have them ‘cause she came with Sassy at her side and the stud is proven. He said there was nothing “anatomically” wrong with her, too. Her cycles just haven’t started back for the spring.
She was bred to him last in Oct., so it wouldn’t have been hard to tell if she had been pregnant. ‘Course, he said she could have stuck and lost it already: possible but not probable.
If it was October last year when she was bred then it may have been that she had just stopped ovulating, even though she was still willing to stand for the stud, or he may have hobbled her and she had no choice but to stand. Hopefully you’ll have better luck in April, but if you don’t then I’d definitely get JB to do the uterine infusions before I switched studs, especially if you really like the stud.
