Guernsey milk in the News:
Channel 5 News contacted me a few weeks ago as they were interested in the A2 properties of Guernsey Milk. Derek Moody of Prosperous Home Farm at Hungerford had put them in touch as they wanted to know about the background information.
88% of the protein in milk is Beta Casein and the varients are A1, A2, B, C, D and E. But in practical terms the important Casein’s are A1 and A2. Genetically cows can be one of 3 Genotypes A1xA1, A1xA2 and A2xA2 but the genes are codominant so that a cow that is A1xA2 will give half her milk as A1 protein and half as A2. For more information regarding the science take a look at the A2Corporation website.
