1. Step-by-step dry milk method This method is suitable for high-yield dairy cows and stops the cows from lactation within 1 week to 2 weeks. The timing of the start of breastfeeding depends on the amount of milk produced by the cows and the difficulty in stopping the milk in the past. For example, cows with large milk production and cows that have difficulty in stopping milk should start early, and vice versa. The principle of gradually stopping the milk is to stop the milk and first start by changing the lifestyle habits, such as controlling the drinking water, strengthening the exercise, changing the number of milking, the number of feedings, and the composition of rations, so as to suppress lactation activities and finally stop milking. . The specific approach is within 1 week to 2 weeks before the scheduled dry milk; stop the massage on the breast first, and gradually reduce the amount of concentrate, juicy feed, and drinking water, but increase the amount of hay feeding, reduce the number of milking, will be daily 3 milkings are changed to 2 times, 1 time, and every other day so that the milk can be dried gradually. Every time you are milking, you have to squeeze it completely. For high-yielding cattle, you should completely stop feeding the concentrate and feed only some hay. When the output falls to 4kg to 5kg on the same day, milking is stopped. This dry milk method is slow and takes a long time, but is suitable for high-yielding dairy cows or cows that have been difficult to stop in the past, as well as cows suffering from mastitis.
2, fast dry milk law is usually 3 to 5 angel cow dry milk. The method is to stop feeding the succulent feed first, reduce the concentrates properly, feed mainly the hay, control the drinking water, and strengthen the activities. The first day milking is reduced from 3 times to 2 times, and the second day is reduced to 1 time. The laws of life have undergone tremendous changes, and the milk production has apparently declined. When the daily milk production falls to 5.8 kilograms, it will stop milking. The last milking should be completely squeezed and the teat should be immersed in 0.5% iodine solution, after which the teat is sealed with collodion. Some use antibiotic ointment to block the teat. This method is mostly used for low-yielding dairy cows.
3, drug injection dry milk method This method applies to all types of dairy cows, less than 10 kilograms of milk per day can use this method dry milk. According to dry milk calculations, dry milk on this day after the cows squeezing milk, the nipple disinfection with iodine liquid, into the nipple into the dry milk drug, and then use the collodion to block the teat.
No matter what kind of dry milk method is adopted, farmers should always look at the situation of the breast. If the breasts become swollen and the milk performance is uneasy, the milk can be squeezed out and dry milk can be taken again. If the breast has inflammation, it should be promptly resolved. After the inflammation is dissipated, dry milk is applied again. The length of the dry period of dairy cows depends on the specific conditions of the cow, usually 45-75 days, evenly 60 days. For mature, high-producing and malnourished cows, the dry period (65-75 days) can be appropriately extended. For cows with good body conditions and low milk production, the dry period can be shortened to about 45 days.
