The milking process of cow has two different ways, first is the traditional way and the second is the Automated Milking System.
According to Alberta Milk the traditional way of milking parlour, cows are milked at least twice a day, usually 12 hours apart. Close to the usual milking time, the cows line up to enter the milk parlour. First the farmer inspects each cow, then he cleans the four teats on the udder before attaching the milking machine cluster. This helps to ensure no foreign material gets into the milk, and it stays high quality. The milking process starts and the milk is piped directly from the cow to the bulk tank where it is quickly chilled.
The Automated Milking System is the milking of dairy animals, especially of dairy cattle, without human labour. Automatic milking systems (AMS), also called voluntary milking systems (VMS), were developed in the late 20th century. If it is time for milking, the cow will enter the milk stall, the machine will automatically clean the teats, attach the cups and start milking. If it is not time for her to be milked, she will be turned away.
We the Valencia Dairy Cooperative, we are still using the traditional way of milking our dairy cows.
