The days when farmers sat on a stool beside their cows to collect their milk are over. The breeders are now assisted by milking machines or robots during the maneuver carried out twice a day. The machines allow cows to be milked efficiently, painlessly, and hygienically. They are installed in milking parlors or sometimes directly in the barn on some smaller farms. The cow's teats should always be sanitized in order to be clean and dry.
