I AI my own mares and the vet helps with the timing. No stocks. If a mare was stinky about the palp or AI (and they are generally ALOT more resistant to a rectal palp then they are about the AI part), I would put them in my horse trailer (a straight load) with a heavy horse blanket draped across the butt chain. Oats in the manager. Very happy mare.
No issues.
However, I had to sell that trailer, and one of my mare’s (who the vet doesn’t like) waved her hind foot at the vet once this spring and the vet got semi-hysterical…said she would NOT palp my mares without stocks, etc. Can’t really blame her…last year a horse kicked and broke her arm while she was taking a rectal temp!
So I had the local carpenter guy built this REALLY heavy sliding “door” on one of my stalls that mimics the door to a stock. Weighs a TON!!
Only trick is that you have to back the mare right up to it for it to work, but since I’m at the mare’s head, it’s ok.
Of course, now the vet has to be the one to slide it back and forth, so that will teach her to complain;)
For AI, I do all of it alone…I have NEVER had anyone hold the mare(s) and they are just standing with the rope draped loosely around the post in the stall. NEVER had an issue…even with maidens.
One mare was abit of a challenge this year because her Schroeder filly kept trying to “help”, but we still (hopefully) got the job done. I’ll know for sure this Thursday.
Now, if I was ultrasounding and had no one to hold the mare, I might consider stocks, but otherwise…see no need.
And in answer to your question, I have a far better conception rate since I’ve been doing my own thing here at the ranch then when I sent my mares out.
But I think it’s more because I care more than 90% of the vets I used…
