Its Cow’s (of specific breed) milk that’s A2 and it doesn’t include buffaloes AFAIK. It does seem intuitive that Indians shouldn’t have any issue getting A2 milk as all our native breeds belong to the specific breed. But as part of ‘Operation flood’, many European breeds were mixed with Indian breeds resulting in much better yield but composition of A1 milk increased. Remember reading somewhere that pure Indian breeds are just 10% of the Indian cow population currently.
I don’t have any scientific studies to share with you as my views on this are purely anecdotal. Check this article for references on how traditional cow rearing families in India and abroad noticed that milk from certain breeds seemed to be ‘better’ for health:
You may be right. My concerns (similar to what I hear from folks interested in buying milk directly from small dairies) is that milk that we get from large dairies is another example of processed food and less healthy.
Yeah, it does make sense.
