Cows’ milk is about 87 percent water and 13 percent solids.
Those solids are a combination of lactose (milk sugar), fat,
protein, and minerals.
If you focus in on the protein within milk, the major
component of that milk protein is called casein. One type
of casein within milk is beta casein. There are two different
beta casein genes that cattle can have - A1 or A2. These two
types of beta casein are found at two different locations, so
any given bovine will be either A1A1, A1A2 or A2A2 for beta
casein.
Why does this matter?
Studies have found that when a person drinks milk, digestive
enzymes interact with A1 and A2 beta-casein proteins in
different ways, so they are processed differently within
the body. Some believe the A2 gene is more natural, and
therefore more healthy. That has led to a recent consumer
demand for A2A2 milk.
True A2 milk can only be produced from cattle possessing the
A2 gene at both locations. So the one and only determining
factor determining whether milk is A1 or A2 lies in the genetic
make-up of the animal producing the milk.
The Jersey breed has a slightly higher proportion of animals
with the A2A2 genes. However, if you are a Holstein producer
who could receive a premium for A2 milk, you can see
from this extensive list of A2A2 sires that you don’t have to
sacrifice much in terms of genetics or switch breeds to attain
that A2 gene preferred by consumers in some parts of the
world.
