1. Stop the milk at a proper time and do a good job in the management of the dry period
Reasonably arranging for the cows to stop production is crucial for the production of dairy cows in the next cycle. When high-yielding dairy cows are stopped milking, the daily milk production is still 10-20 kg. In order to stop the production of cows within the specified time, it is necessary to timely adjust the diet on the feeding, reduce the amount of feed and green feed, and reduce the number of milking. Gradually dry milk and fast dry milk are used to stop the milk. The choice of stopping milk should be based on the health status of the breast. For cows with chronic mastitis, gradual dry milk should be used to stop milk. The cows with healthy breasts can use the fast dry milk method. No matter which dry milk method is used, Pay attention to the changes in the breasts, if necessary, after the final milking in the milk pool into the antibiotics to prevent the occurrence of mastitis. With the above two methods, most milking cows stop production within 10 days and enter dry milk. For dairy cows with a history of mastitis, attention should be paid to changes in the breasts after stopping the milk and abnormalities should be dealt with promptly.
2. Timely breeding
Breeding at the right time will help improve the productivity of cows and reduce the cost of production. Breeding cows will begin breeding at 16-18 months of age. The production of cows should be based on the recovery of the uterus, take the necessary rehabilitation measures, the cows do not place over the tires, we must promptly use the disinfectant liquid, rinse the uterus every other day, until the recovery. For those who have fever, intramuscular injection of antibiotics should be used. The cows who normally discharge the placenta should be treated with a disinfectant solution and rinsed 2-3 times. As long as the cows are properly managed, the uterus is not inflammatory and can be bred within 45 to 60 days after calving. For healthy cows that are not estrus for more than 60 days, drug aphrodisiac should be used to allow the cows to be mated within the prescribed period of time to ensure that the cows produce one year's worth of food.
3. Strengthen cow immunity and disease prevention
Dairy cows are health-immunized every year in the spring. According to strict quarantine procedures, dairy cows are required to conduct regular quarantine of brucellosis and tuberculosis every year. In addition, they must be vaccinated against related diseases to prevent the occurrence of infectious diseases. Secondly, all the facilities of dairy farms must be cleaned and disinfected once a year. Dairy cows' milking tables and sports fields must establish strict disinfection measures. Disinfecting medicines should use 2-3 kinds of alternate disinfection. While doing a good job of disinfection, killing mosquitoes and flies, and regularly cleaning up feces is also a necessary measure to prevent the spread of infectious diseases. Closing good feeds and not feeding mildewy moldy fodder will enhance the constitution of the cows and reduce the incidence of diseases. The important way.
