Some do ship frozen, but most don't, in horses I have been told frozen is tough to get the horse breed. You have about and 48 to 72 hour window from the time the semen is collected to AI the mare. the semen is collected and usally shipped within a couple of hours (fed ex) there is a special contanier involved, but I believe it only contains 1 or 2 straws...not too special.
My problem is that after the stud fee and inital vet cost it's $250 each time you ship semen and more vet cost. We tried our mare 3 times this spring, $750 extra in just shipping cost and about $600 in extra vet cost and still not bred. The Stud has a good sperm count, I know the vet missed her once and we tried once on the foal heat. But is there an average number of tries? I would love to hear some more from people who have tried. I'm I having some bad luck or does it take 3 or 4 tries? The yet to be concieved foal is getting very expensive.. we are now waiting to breed her until next Feb or March.
