Milk is a good source of protein, calcium and other nutrients, so it is highly recommended that people of all ages include it in their daily diet. Though milk of goats and some other animals is also edible, usually most people are drinking cow and buffalo milk.
Earlier most cows were milked manually however with advances in technology, automatic milking machines are used in large dairy farms. Small farmers with only a few cows continue to milk their cows manually.
The milk collected from the cows and buffaloes is either used directly or processed by the milk dairies
