'New' semen thawing technique


Earlier this week a couple of farmers forwarded me the following text messages they had just received:

CRI-SA PRESS RELEASE! WE OFFER AN EASIER SEMEN THAWING PROCESS. UNIQUE TO CRI SEMEN. We want to save you time & get more cows preg! MORE DETAILS TO FOLLOW...

CRI-SA 'POCKET THAW' CRI'S UNIQUE PROVEN THAWING METHOD-NO MORE WATER & THERMOMETERS REQUIRED. SIMPLY A CRI STRAW; A PAPER TOWEL & S POCKET. EASY?...

I checked the CRI website but as of Wednesday night there was no mention of it there. Has any body else heard about this?

At least fifteen years ago I attended a Farmer's Day run by the local AI company, one of the speakers they had brought along was a wild man from the Zululand thornveld that ran a huge herd of Brahman breeding cows. He was there because he had a very succesful artificial breeding program. He did a lot of synchronization and batch mated. To the horror of convenors he proceeded to describe his actual AI methods, he used no water to thaw the semen but merely rubbed the straw in his hands for a couple of seconds, loaded the gun and popped it in the cow. With very good results. We were cautioned that though it worked for him, we shouldn't try it at home and should rather stick to the conventional methods for semen preperation . . .

I was on the road with a CRI guy two weeks ago and he told me that too. I asked around here and nobody seemed to know about it. What he told me was, that they use a milk based diluter instead of egg based.

this is not new!
my husband had been doing this for years however if you use maxis conception rate will be sh.thouse because of the diameter of the straws,something along the lines of re freezing etc.we were getting a lot of unfertilized eggs in our et work and on the recommendation of our et vet we now thaw in 38 degree water with much better results.
