I am interested in the research on A1 and A2 milk and its assocaition with crohns after reading Keith Woodfords book  'The Devil in Milk' 
Has anyone has swapped to A2 with good results? 
I am looking at the SCD diet and thought it may be even better if I made the yoghurt with A2 milk.

So what is the association between A1 milk and CD? Why is A2 better?

Wow, thanks for bringing this up.

Wikipedia has a good explanation:

In general I think it's a good idea to use A2 milk. However, in most countries, cow's milk isn't labeled to distinguish A1 from A2 (it should be, by law, but the dairy industry objects). New Zealand is one of the few countries that require labeling. The alternative is to buy goat's milk, which is A2 by default (there is no such thing as A1 goat's milk). The big problem with goat's milk is the price, about 4 times more than cow's milk.

Cow’s milk contains six major proteins. Four are casein proteins, the other two are whey proteins.
Casein proteins make up about 80 percent of the protein in cow’s milk.
A type of casein called beta-casein is one of the major ones, and is itself of different kinds, depending on the genetic make-up of the cow. The most common are beta-casein A1 and beta-casein A2. Milk high in beta-casein A1 is being referred to as ‘A1 milk’ while milk high in beta-casein A2 is being called ‘A2 milk’.
Milk we buy normally contains a mixture of A1 and A2 beta-caseins as it comes from mixed herds. Freisian cows produce mostly A1 milk, while Guernsey cows, sheep and goats produce mostly A2 milk.
It is beleived by many well respected people in the NZ FDA community that although not a cause of crohns, this A1 casein is the reason why many crohns sufferer's and other with digestive tract problems have difficulties with dairy products.
I kinda feel the govt line in the past has been a bit closed because NZ s dairy industry is mainly A1 herds .... very interesting research :)

My DD may be put on a dairy free diet to rule out casein allergies....maybe we'll try finding goat's milk first. But what about lactose? Anyone making lactose free goats milk? I guess I can just get lactase enzyme and drop it into the glass....
