I will take an educated guess for you to get things started here.

Possible scenario's.

1) The A1  protein could theoretically be removed from milk by some form of  processing. The resulting A1 free milk would attract premium prices in some markets.

2) The level of A2 protein in milk may be able to be increased by breeding i.e. will take years or decades.

3) Similarly the elimination / reduction of A1 protein could be achieved by breeding also. Remember the gestation cycle for cows is effectively 12 months.

4) The time frame for both options 2 & 3 above could be reduced by the use of Genetic Engineering techniques (if the Greens let them).

5) The A2 protein could be extracted from milk, be concentrated or dried then be used to create new  high value Nutraceutical products. This seems to be the most logical approach.

Proteins form only 1% of milk so these proteins will be only a small fraction of that i.e. a huge quantity of milk is needed to yield a small volume of A2. It will be some time before this gets commercialised.

The elimination of the A1 variant from fresh cows milk products could save millions of lives worldwide.

Any scientific chatters able to determine whether this A1  variant is able to be" removed/changed" from milk or does it make those cows worthless?

What worth the A2 cows?

disc :was thinking of buying (to lease) some cows this season!!!!
