A1 vs A2 Milk
- Milk contains about 85% water. The remaining 15% is the milk sugar lactose, protein, fat and minerals. Beta-casein (protein) is about 30% of the total protein content in milk.
- A2 milk is the milk that contains only the A2 type of beta-casein protein.
- A1 milk contains only A1 beta casein or A1A2 type variant.
- The A1 protein variant is commonly found in milk from crossbred and European breeds of cattle.
- A2 milk is found basically in indigenous cows and buffaloes of India (Asia as a whole).
- A2 milk is gaining popularity because some studies suggest that A2 milk may be easier to digest for some individuals than A1 milk.

Punganur cow is a significant national treasure, in the sense that it has a lot of nutritional advantages and cultural relevance. I find myself greatly intrigued by the high-fat content and A2 milk properties. It seems like such a healthier and more sacred choice. It’s very encouraging to see both the state and central governments joining hands to conserve this wonderful breed, so rare and so much of tradition. Such awareness is what is most required throughout the country for the protecting and promoting India’s heritage in livestock.
