1. Improve feeding management, especially in the dry period, perinatal period, and lactation period. The main measures are: pay attention to feed selection, balanced dietary nutrition, and various nutrients meet the physiological needs of dairy cows. During the dry period, it will reduce the amount of concentrate feed, increase the amount of roughage feed, stop feeding the juicy feed, and pay attention to calcium, phosphorus and other minerals. In the early perinatal period, the amount of mixed concentrate is increased to reach 1% of the weight of the cattle, and the amount of calcium is reduced to half of the dry period; the amount of concentrate feed is reduced in the postpartum period, and it is reduced to 3 days after the birth. 0.5%, and immediately restore the calcium feed level to dry milk level, 4 days after delivery began to gradually increase the concentrate material, while feeding silage. The period of lactation guarantees the intake of dry matter, increases the ratio of refined to dry matter, and increases the energy concentration of the diet and the amount of juicy feed. Through the strengthening of feeding and management, the cows will be in early stage of estrus.
2. To reduce infertility incentives prevention measures focus on eliminating incentives. For example, do a good job in environmental sanitation, keep the cowshed clean and ventilated, and especially pay attention to the stress that the environment changes bring to the cows. In the cold season, it is necessary to strengthen warmth, and in the hot season, it is necessary to do a good job of preventing the heatstroke from cooling. At the same time, it is necessary to increase the movement and light of cows in order to improve their health level and reduce and avoid infertility.
3. Preventing Uterine Infection During the breeding and inseminating operations for cows, the cultivator must strictly follow the rules of operation. The cow's vulva, insemination equipment and arm must be strictly disinfected. Insufficient disinfection during childbirth and midwifery, and careless operation, it is also easy to bring pathogenic microorganisms into the uterus of cows and cause infections. In particular, the uterus is particularly prone to infection when it is peeled off. This can be done in the uterus after the burdock has been removed. Place 2-4 grams of oxytetracycline or 2-3 grams of aureomycin.
4. Timely Treatment of Diseases Cows should strengthen nursing care after delivery and reasonably distribute rations to ensure that nutrition is comprehensive and balanced. Attention should also be paid to observing changes in the spirits, appetite, and feces of dairy cows, and timely treatment should be found, especially after 30 to 40 days after childbirth. Restoration of the uterus should be performed to ensure its healthy constitution and to promote conception. For cows that are not estrus for more than 2 months post-partum and have been bred for more than 2 times, the reason for the disease is that the cow should be promptly treated for diseases of the reproductive system and eliminated if necessary.
5. To do a good job of health and epidemic prevention, we must establish a strict and standardized disinfection system. The cattle farm should conduct a total disinfection once every quarter. The cowshed should be disinfected once a month. The sick cowshed and delivery room should be cleaned and disinfected every day. Regular cleaning and disinfection of the feeding trough; TB and BB quarantine should be conducted every spring and autumn. The detected cow should be isolated and treated in time. When the cow is threatened by certain infectious diseases, the vaccine should be vaccinated urgently and taken in time. Measures to prevent proliferation, protect healthy herds; additionally. When purchasing dairy cows from other cattle farms, the necessary health checks should be performed, especially the inspection of reproductive system diseases.
