Looking at in another way
Q: How much milk does NZ produce in a year?
A: Approx 20,000 million litres.
Q: How much of that milk is 'pure' A2 (i.e. the cow is homogeneous A2)?
A: Approx 30% or 6,000 million litres.
Q: How much of that 6,000 million litres is actually from certified A2 cows in A2 only herds?
A: Don't know, but lets us say 5% or 300 million litres.
Q: If the demand is there and the economics work out, like if there is a sufficient premium for A2 over non-A2, would it be possible to screen the existing herds for A2 cows and do a little cattle shuffling to increase the size of certified A2 cows in A2 only herds?
A: Absolutely.
Q: By how much?
A: Lots.
Q: Will that Satisfy Snoopy?
A: We will have to wait and see.
