Genetic AUSTRIA GmbH has tested a selection of Fleckvieh bulls for the ß-casein status

Tuesday 01 December 2015

ß-Casein A2 Genetic AUSTRIA GmbH has tested a selection of Fleckvieh bulls for the ß-casein status – A1A2, A1A1 or A2A2. In milk, the casein proteins can either be A1 or A2 or a mixture of the two. The A1 proteinbehaves like an opiate and epidemiological studies have implicated the A1-protein in heart disease, type 1 diabetes, autism and schizophrenia as well as digestive upsets amongst some people.

  

Goat andhuman milk, as well as the milk from BosIndicus cattle breeds is A2, however a mutation occurred in European (Bos Taurus) breeds 5,000 – 10,000 years ago which caused some cows to produce the A1 beta-casein.

The percentage o fcows that are homozygous A2 varies between breeds. Branded A2-milk and dairy products are available in New Zealand, Australia, UK, and Chinawith future plans to launch A2 milk in the US.Of the 41 Fleckvieh bulls sampled 7% tested A1A1, 54% tested A1A2 and 39% tested A2A2 – the following bulls are homozygous A2:
