Step 1, clean the nipples. Specifically divided into three processes: washing, drying and massage. When washing, care should be taken not to wash too much area, because the area is too large will make the upper part of the breast with the water flow, concentrated in the nipple, so that the opportunity to increase the nipple infection. After washing, wipe off with a clean towel, paper towel, or waste newspaper. Note 1 towel or 1 piece of paper for 1 cow. After washing, disinfect the towel. Then massage the breasts to make the milk release. This process should be gentle and fast and it is recommended to complete within 15-25 seconds. In step 2, we discard the first 1-2 milk. This has the following effects: it enables milkers to detect abnormal milk and clinical mastitis early; abandon milk containing high bacterial counts from milk ducts; and provide a strong irritant stimulus. Squeeze the first 1-2 milks before cleaning the nipples or after cleaning the nipples. It is recommended that it be done before the teat is cleaned, as this will give the cow an intense booster stimulation. Waste milk is packed in special containers to reduce environmental pollution. Step 3, the medicated nipple. Experts recommend immersing the nipples with a disinfectant solution before milking, then leave for 30 seconds, then wipe them with a tissue or towel. It is necessary to implement this procedure on cattle farms with poor sanitation or mastitis caused by environmental problems. The recommended procedure for the nipple bath is as follows: remove the sundries and other debris on the nipple by hand; discard the first 1-2 milks per 1 nipple; make a medicinal bath for each nipple; wait 30 seconds; wipe dry. Note: If the nipple is very dirty, it should be washed with water before the medicinal bath. In step 4, if you use a machine to milk, you should pay attention to the proper use of the milking machine and observe that the milking machine is working properly. If the machine is not working properly, the milk will not be completely filled or damage the breast. Manual milking should minimize the milking time. Step 5, milking the nipple after milking. After 15 minutes of milking, the circular sphincter of the nipple restored contractile function and closed the nipple hole. Within 15 minutes, open nipple holes are vulnerable to environmental pathogens. The medicine bath is carried out in time so that the disinfectant adheres to the nipple to form a protective film, which can greatly reduce the incidence of mastitis.
