FREEZING EXTENDERS

Postby lotsofponies » Tue May 21, 2013 6:01 pm

I have been testing my boys to see which extender they ship best in and got to think about freezing extenders. If one was going to freeze one's stallion would you take in consideration what extender they shipped best in to centrifuge and freeze. For example if Sparky ships best in Inra 96 would Inra 96 be best to centrifuge and freeze in InraFreeze. I know Colorado State vet school devolped freezing using Ez Mixin but know that there are more choices do you test the different ones.

No. There is little or no comparison. You will need to do a test freeze in multiple extenders and thaw and evaluate results. Even then, there's no guarantee, as fertility is not totally correlated to motility.

So if I'm going to freeze the first collection would be a test freeze where the semen is frozen in the different extenders? Then a second freeze would be in the stallions favorite extender, how many different freezing extenders are there to test for? I guess it was easier when there weren't as many choices of freezing extender and then slow cool or fast freeze to add to that. Life is getting so complicated. :8:

We typically try in 4-6 extenders on the initial test freeze and then if we don't get adequate results will do another test freeze with different extenders.
