Frozen Semen Straws
 
If a stallion owner sends you 5 straws of semen, is that 5 different inseminations if you choose or should you administer all 5 at once, half at a time, etc? I AM NOT BREEDING, I'm not really new to horses but I am new to all of the knowledge that comes with them & this is just one of the subjects I'm trying to learn about now (along with gaits & color genetics) :D Thanks

I'm surprised nobody that has looked at this post knows the answer, especially as common as AI is in the horse world :cry:

I'm also curious. I'm looking into embryo transfer and semen collection for goats (haven't studied it yet) - I bet it's similar with horses.

It depends. There should be explicit instructions that accompany frozen semen that tells how many straws make up an insemination dose. We typically freeze in 5 ml straws and one straw is usually an insemination dose. When purchasing a frozen semen breeding, many come with no live foal guarantee and you will then buy the semen by the dose. If 1/2 ml straws are used, it can take anywhere from 3 to 4 straws per insemination dose to up to 12 straws per insemination dose. With frozen semen, you try to breed as close to ovulation as possible. There are a couple different protocols that can be used, but the standard in the industry is to breed within 6 hours of ovulation. Since you can't exaclty predict ovulation prior to it occurring it usually means that you are going to be breeding post ovulation.

Hope that helps!
