During the lactation period of dairy cows, the lactose content in the mixed milk squeezed every month is not much different from the average value, generally only 0. 1-0.2%.

It can be decomposed into α -lactose and β -lactose Lactose can provide the energy needed for growth, and it is the driving force for the development and activities of organs, nerves, limbs and muscles in the body. The development of brain cells and the health of the whole nervous system require a lot of lactose.
There are enough lactase in the digestive tract to decompose lactose, which can decompose, digest, absorb and utilize lactose well. Lactose can promote the reproduction and growth of lactic acid bacteria in the baby's intestine, and has a protective effect on the stomach.
