Cultivating high-yielding dairy cows is closely related to raising feed remuneration, reducing feed costs, increasing milk production, and increasing economic efficiency. From the point of view of dairy cow production practices, there are many factors that affect the milk production of dairy cows, among which the breeding work is the prerequisite for creating high yields. Feeding management is the key to the production of milk production performance. In order to cultivate high-yield and stable-producing dairy cows, we must focus on the following ten technical measures in feeding and management.
Strengthen breeding and improve milk quality
To speed up the cultivation of high-yield dairy cows, we must continuously reduce the number of low-yielding dairy cows, and pay attention to the selection and breeding of the original varieties, and adopt a planned and continuous introduction of fine breed bulls (or frozen semen) to carry out blood renewal to achieve the same improvement as soon as possible. Dairy production levels.
Adapting to local conditions and improving feed production
Feed is the material basis for breeding high-yielding dairy cows. To widen the sources of feed, refined and roughage should be sufficient and diverse. The solution: First, engage in more stable basic feeds such as silage corn, hay, and roots, so as to timely adjust and stabilize the supply of nutrients. The second is to grasp the supply of green and juicy succulent feed, and pay attention to reasonable collocation and utilization. The third is rational processing, making full use of various agricultural and sideline products that can be used as feed, expanding feed sources, and reducing feed costs.
Pay attention to rearing and nurturing healthy calves
Cultivating healthy calves is a prerequisite for achieving high yields of dairy cows. During the breeding process, the feeding and management of pregnant cows need to be strengthened to ensure that the pregnant cows are robust. After cows are born, the amount of green feed must be controlled to prevent diarrhea in calves. If yaks are found to have symptoms of loss of appetite, diarrhea, etc., they should be promptly isolated. The yak houses should be kept warm and dry to prevent thief and dampness. The yak barns are regularly sterilized and disinfected for one month before the yak can be placed. In addition, yak can not feed silage, and all kinds of preventive measures must be timely.
Early identification, prediction of milk production capacity
Early identification of calves, the use of directional cultivation methods to develop high-yielding dairy cows. The thickness of the nipples and cows of newborn yaks is closely related to pedigree. The nipple is flat, elastic, wrinkles are more, the base is slightly wider, and the length is about 20 mm. After the group is transferred, the breasts are well developed, the mammary glands are developed, and the milk is released quickly; on the contrary, the nipples are round, and the elasticity is poor, and the milk is slow.
Extensive feeding can increase feed intake
The production practice has proved that during the entire yak and breeding stage, the feeds carry out the refined-coarse-fine procedure, that is, they should be extensive during the breeding period and intensively reared after pregnancy. In this way, bred cattle can enhance the digestive function, increase the gastrointestinal volume, and provide favorable conditions for the later high-yield.
Adequate feeding, high yield performance
Feeding enough is for the cows to eat enough. If one-sided pursuit of quality, only focusing on concentrates, ignoring the structure of the diet, inadequate intake of crude feed, will result in weakened digestion of the cow and physical deterioration, milk production will decline. Therefore, feeding dairy cows should be dominated by high-quality green hay, greenish juicy materials, and tuber-based feeds, and concentrates can only be used as a nutritional supplement. In addition, in the case of high protein levels, special attention must be paid to protein and carbohydrates, as well as the balance of calcium and phosphorus, otherwise it will affect the health of lactating high-yielding dairy cows.
Strengthening the milking of dairy cows
To keep milk cows dry during the milking period, we should adopt the fast stop milk method that stops milk without stopping, and generally stop for 3 days to 5 days. The dry period is generally 60 days to 70 days. Dry milk body is more important than the highest milk production by 10% to 15%.
Scientific breeding, reducing feed costs
The purpose of scientific and rational feeding is to use the lowest feed consumption in exchange for the most livestock products, that is, to ensure the health of the cows, and to fully develop the production potential and feed efficiency of the dairy cows.
Step up measures to prevent cows from becoming infertile
Preventing dairy cows from infertility is an important measure to accelerate the breeding of dairy cows and speed up the cultivation of high-yielding cows. To prevent cows from becoming infertile, pregnant cows must be made nutritionally appropriate before birth and cannot be fed too full to ensure that there is a sufficient supply of nutrients and vitamin feed.
Pay attention to proper exercise to strengthen the body of dairy cows
Cows adhere to reasonable exercise, can help promote the blood circulation of dairy cows and enhance the appetite of dairy cows, can accelerate the growth and development of yak and bred cattle, and can increase milk production of dairy cows. In addition, it can effectively strengthen the body of dairy cows. In addition to free activities on the playground every day, cows should also drive away from 3 km to 4 km.
