Contamination caused by milkers, cattle, utensils, dust, mosquitoes and flies. Strictly follow the procedure 1, milking times and intervals In addition to feeding and management, the number and interval of milking have a greater impact on the milk production of dairy cows. Fixed milking time and even milking interval are all conducive to maximum milk production. Under normal circumstances, milking is performed every day. Two times, the best milking interval is 12 hours and 1 hour intervals of more than 13 hours, which will affect milk production. Milking 3 times a day, the best milking interval is 8 hours and 1 hour. Generally, the milking output 3 times a day can be increased by 10% to 20% compared to 2 milkings. 2, milking procedures Check for signs of redness, swelling, heat pain, or trauma before viewing or touching the outside of the breast. Cleaning the breasts and nipples Dairy cows should be kept clean and dry. Only the nipples can be cleaned when the breasts are clean. When the breasts are dirty, clean the breasts with warm water of 40°C to 50°C. Discard the 1st ~ 3th milk to check whether there is clot, flocculent or water-like milk in milk, clinical mastitis can be found in time to prevent mastitis milk mixed into normal milk. Nipple pre-medicine bath with a special nipple disinfectant to the nipple surface of the bath for not less than 30 minutes. A bath appointment can reduce the number of bacteria in the nipple skin, reduce 50% of environmental mastitis, and reduce the incidence of new mastitis (43% to 51%). Dry the teat immediately after drying the teat and the tip of the nipple. If it does not dry, it will flow into the milk. You must use a sanitary disposable towel or paper towel to prevent cross-infection of mastitis. Massage the nipples while wiping the nipples, and massage the nipples horizontally.

The palm and the lower part of the nipple are on the same level, so that the milk is not stained and the nipple is not damaged. Thus, the uniform and fast speed is not easy to fatigue, but the short nipples are not easy to carry out. The other is acupressure: using the thumb, forefinger or forefinger, the middle finger holds the nipple and slides the nipple from top to bottom. The disadvantage is that it is easy to hurt the nipple, often causing the nipple to be deformed, and it is slow and not easy to squeeze dry. Generally about 80 to 100 milkings per minute. For high-yield cattle, double milking can be carried out. After squeezing it dry, use a dry towel to clean it, and then close the milk tube with liquid medicine. To prevent bacterial intrusion, mastitis occurs.
