Due to the difference in availability, A1 milk is relatively cheaper and easier to find than A2 milk but A2 milk se better and good quality. However, recently there has been a difference in opinion about the health effects/benefits offered by each type of milk
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, Sahiwal etc.
ere is a difference in the ratios of lactose (carbohydrate component) and fatty acids (fat component) in both milks.
