A1 versus A2 milk: The position of the organised dairy industry
The difference between A1 and A2 milk is associated with a variation in the protein composition of cow’s milk. Both A1 and A2 variants are proteins in the casein group, which makes up around 80% of proteins. The two variants are almost identical, apart from one amino acid at position 67 of the polypeptide (amino acid chain) – A1 has histidine whereas A2 has proline.
The milk of modern dairy breeds differs in their composition of A1 and A2, with the highest frequency of the A1 variant observed in Holstein (0,31 to 0,66) and Ayrshire (0,43 to 0,72) breeds, and A2 in Guernsey (0,88 to 0,97) and Jersey (0,49 to 0,72) breeds. Being the most popular breed and providing the most milk, the Holstein introduces a comparatively high proportion of A1 milk into the South African market.
