A1 and A2 Milk anyone studied this

[gwpoky]

Was looking at some articles on A1 and A2 milk, very interesting, may have to take this into serious consideration when purchasing our next cow? Has anyone on this forum studied this or know any good studies about it.

thank you,

I have done some looking into A1/A2 studies. If I were going to buy a cow and I had a choice between the two, I go for the A2/A2 cow as first pick, then I’d pick an A1/A2 cow and breed her to an A2/A2 bull with the hopes of getting an A2/A2 heifer. Here’s a link I have

A friend of mine uses the A2/A2 as a marketing tool for his dairy, so there must be some consumer knowledge of it. Here is his website: http://oldsilvanacreamery.com . Here is a link to my blog with more pics of his operation: http://bluecreekdairy.com/blog/files/af7eb80adfcc2d78516242ab355a4956-24.html

Me personally though, I’m not convinced of the merits of A1 vs A2 (If you can even test for it anymore). I think any problems (if there are any!) with milk are the results of much more recent events, such as confinement on concrete or the over feeding of grain., not something that happened thousands of years ago. But, I’m not willing to concede that there are no merits of A2 over A1. I just haven’t been convinced yet!

All things equal, I’d choose colored breeds over black and whites.

A2 is also used to market the heifers/cows to prospective buyers so expect to pay more as well.

Evidence from several epidemiological studies and animal models does not support the association of milk proteins, even proteins in breast milk, and the development of T1D. Ecological data, primarily based on A1/ A2 variations among livestock breeds, do not demonstrate causation, even among countries where there is considerable dairy consumption.
