3. The process of milk production by dairy cows🐮
1. Lactation period: After giving birth, the mammary glands of the cow begin to secrete milk. This period is called the lactation period. During this stage, the cow's milk production gradually increases, usually reaching a peak in the 3-4 weeks after parturition.
2. Peak period: In the late lactation period, the milk production of dairy cows reaches its highest point. This stage is called the peak period. At this stage, cows can produce 30-40 kilograms of milk or more per day.

4. Milking management: Correct milking method and frequency are very important to maintain the health of dairy cows' mammary glands and increase milk production. Generally speaking, milk🥛 needs to be expressed 2-3 times a day to maintain smooth mammary glands and normal secretion of milk.
