Early-lactation milk contains colostrum, which carries the mother's antibodies to its young and can reduce the risk of many diseases.It contains many other nutrients including protein and lactose.

Alvarez and Francisco Parada-Rabell, Department of Food Science and Technology, The Ohio State University.Milk from healthy cows contains relatively few bacteria (10 2-10 3 /mL), and the health risk from drinking raw milk would be minimal. However, milk is a natural food that has no protection from external contamination and can be contaminated easily when it is separated from the Dairy industry data shows that 75% of diseases in dairy cows occurs during the critical sixweek period which is 3 weeks prior to calving and 3 weeks after calving.
