Three dry milk methods suitable for farmers
Lactating cows stop milking about 2 months before calving, which is called dry milk period. The following three dry milk methods are introduced for reference by rural cattle farmers. The gradual dry milk method began to change the feed about 10 days before the scheduled dry milk, gradually reducing the amount of green and juicy feed and concentrates, increasing the amount of hay fed, controlling the drinking water, and stopping the breast massage. The milking was changed from 3 to 3 times a day. 1 time, 1 time every other day, disturbing the milking time, taking measures to increase the time for cows to exercise and disrupt the living habits of cattle. When the milk produced falls to about 5 kg, milking is stopped. In the last milking, the milk was squeezed, the nipples were immersed in 0.5% iodine solution, and then the teats were soaked in small cups for 3-4 times. This method is mostly used for high-yielding dairy cows. The fast dry milk method is generally 3 to 5 angel cow dry milk. The method is to first stop feeding the succulent feed, reduce the concentrates properly, feed mainly on hay, control the drinking water, and strengthen the exercise. 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 dropped significantly. When the daily milk production falls to 5-8 kg, milking is stopped. The final milking should be completely squeezed. The teat should be immersed in 0.5% iodine solution, then the teat should be used to seal the teat. Some use antibiotic ointment to block the teat. This method is mostly used for low-yielding dairy cows. Drug injection dry milk method This method applies to all types of dairy cows, and less than 10 kg of milk per day can be used to dry milk. According to the dry milk plan, dry milk is used to squeezing the milk from the cows after the milk is removed. After the nipples are sterilized with iodine liquor, dry milk drugs are injected into the teats, and then the teats are sealed with collodion. Experience has shown that no matter what kind of dry milk method is adopted, farmers should always observe the situation of the breast. If the breast swells and hardens, when the performance of the cow is uneasy, the milk can be squeezed out and dry milk measures can be taken again. If the breast has inflammation, it should be treated in time. After the inflammation disappears, dry milk will be performed again. The length of the dry period of dairy cows depends on the specific conditions of the cow, which is generally 45-75 days, with an average of 60 days. For mature, high-producing and malnourished cows, the dry period (65-75 days) can be appropriately extended. For cows with good body condition and low milk yield, the dry period can be shortened to about 45 days. Dry milk formula (a cow dose) 40 ml soy oil, 1 million units of penicillin, 1 million units of streptomycin, appropriate amount of sulfonamide and glycerol, add the above drugs after disinfecting the soybean oil, and use a needle-free method for each nipple of the cow. Syringe can be injected into 10 ml. Some farmers choose eye ointment such as chlortetracycline or oxytetracycline and inject 10 grams into each nipple. The effect is also very good.
