A1/A2 casein testing

[allmuxedup]

So, who has tested their cattle & what was the result?
I'll be headed back to the farm soon (I hope!) and we'll test all our cattle for they're beta casein type. I'm just wandering what most people had found.
We're hoping to milk a few of the cows (one is heavy in Woodmagic on the bottom side.) I'm torn about using the A1 cows as nurse cows, for dairy steers. If the A1 milk isn't good for us, how can it be good for them? Do I want to eat beef raised on A1 milk? I have no doubt that I have been, but I haven't had a choice. If I get some dairy steers, I won't be eating them anyway. So, that might be the way to go. We'll put the babies of the cows we milk w/ the other cows, they all nurse each other's babies anyway. We caught the bull nursing a few days ago. He's now banished to a pasture all his own.

So, how about it.... who's tested & what did the test show? Are Dexters a very high % A2?

we've tested three of our Dexter cows for A1/A2 Beta Casein gene. Here were our results:

Rainbow Hills Holiday, ADCA No. 10409, AC - heterozygous A2 producer (this means she has one allele in the gene pair that codes for A1 Beta Casein and one allele in the gene pair that codes for A2 Beta Casein) - so she produces both A1 and A2 Beta Casein in her milk.

Hillside Mornin Glory, ADCA No. 11993, AC - heterozygous A2 producer - she produces both A1 and A2 Beta Casein in her milk.

Bohls Diamond, ADCA No. 14288, CC - homozygous A2 producer - she produces only A2 Beta Casein in her milk.

We have tested all of our Kerry cows and bulls and they are all homozygous for A2 and will produce only A2 Beta Casein in their milk.

We have CSS certified semen available for sale for Kelmscott's Seamus, our first registered Kerry bull. Kerry bulls can be used for crossbreeding Dexter cows, because their calves are small (55 to 65 pounds at birth). Here is a photo of Kelmscott's Seamus:
