Shiv Organic farms deliver the Best quality Gir cow A2 milk in Nagpur, 100 % pure and fresh from the farm to your door step. Our farm is located at Nagpur. The milk that comes from desi Gir cows is called A2. It has an A2 type of protein, which is a naturally occurring protein that comes from desi cows and is very nutritious and simple to digest. A1 is a gene that is present in cows of foreign breeds. When hybrid cows are produced, a single gene is combined with the genes of the Indian cow. A1 milk refers to this milk because it contains the A1 gene protein. This milk is not as nutritious as A2 milk and is difficult to digest. BCM-7 (casomorphin-7) is a protein that is difficult to digest and is the main ingredient in hybrid breed milk, such as A1 milk.
