Veterinarian Mark Lopez of Wholesome Dairy Farms demonstrates how to milk a cow. Use a teat dip to wet the teats. Then, massage in the fluid so it loosens up the surface dirt and kills bacteria. Stimulate the teat end with your fingers. Next pre-strip the cow by gently pulling on the teat and mimicking the suckling action of a calf. Let the iodine teat dip to sit on the udder. When the cow squirts milk out of the teat, it means that she is stimulated and comfortable. Take a clean towel and wipe off the teat dip. Gently twist the cloth to clean the teat. Examine the teat to make sure it is clean. When the teat is dry, attach the milking machine to the cow's teat to complete the milking process.
