Is jersey milk a1 or a2. Since all Holland Jersey cows only have the A2 gene all our milk is A2 milk and all our products are made with A2 milk. Friesian cows produce mostly A1 milk Jerseys and Guernseys produce mainly A2 milk. In the book Devil in the Milk Professor Keith Woodford explains the differences between normal milk and A2.

The difference between A1 and A2 milk is the structure of the milk protein casein. This protein exists in two forms. A1 beta casein or A2 beta casein.

Research has found that A1 milk isnt as good for health as A2 milk. A naturally white and creamy popular drink milk is a common choice of beverage in all age groups from young to old. A1 beta-casein can be found on all commercially-prepared milk.

A2 beta-casein is protein found in milk produced by old-fashioned cows like the Jersey Charolais Guernsey and Limousin. Milk produced by other mammals such as those from human goat and sheep is similar to A2 dairy milk mainly due to the presence of proline 6 7. So does that mean all foreign breeds produce the supposedly toxic A1 milk.

The A1 protein is much less prevalent in milk from Jersey Guernsey and most Asian and African cow breeds where instead the A2 protein predominates. This includes breeds like the Guernsey Jersey Charolais and Limousin. Regular milk contains both A1 and A2 beta-casein but A2 milk contains only A2 beta-casein.

Some studies indicate that A1 beta-casein may be harmful and that A2 beta-casein is a safer choice. This is the reason for the A1 vs A2 debate. A1 milk is obtained from cows of Western origin like Holstein Friesian Jersey etc.

And yields large quantities of milk. A2 milk on the other hand is obtained from cows of Indian origin like Gir. A2 beta-casein on the other hand is a major component of the milk of Guernsey and Jersey cows Charolais and Limousin Southern French breeds Channel Island and Zebu cows Africa South Asia.

Milk from breeds of cows that originated in northern Europe is generally high in A1 beta-casein. These breeds include Holstein Friesian Ayrshire and British Shorthorn. Yes A2 might be an option for him.

I should clarify that Jersey milk is mostly A2 casein. Depending on the genetics of the cow herd some Jersey milk may also contain some A1 casein. Ask supplierfarmer if they know the A1A2 content of their milk.

This is why A2 milk is often referred to as original milk. Especially Jersey cows Guernsey cows cows of the Brown Swiss breed as well as part of the Simmental breed predominantly give the desired A2 milk. In Europe today a mixture of A1 and A2 milk is usually produced.

There are many different types of milk proteins. One particular protein beta casein comes in two forms. About 60 of beta casein comes in A2 but how much is in each milk depends on different breeds of dairy cows.

Holstein Friesian Jersey Brown Swiss. More than 46-70 A2. A1 and A2 proteins in milk are both safe to consume.
