Intensifying breeding and improving the quality of dairy cows To speed up the cultivation of high-yielding dairy cows, we must continuously reduce the number of low-producing dairy cows, and pay attention to the selection and breeding of the original breeds, and adopt planned and continuous introduction of fine breed bulls (or frozen semen) to carry out blood Update to reach the level of production of cows of the same breed as soon as possible.
Adapting measures to local conditions and improving the feed production of feeds are 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.
Attention to feeding and nurturing healthy yaks to cultivate 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 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 breeding can increase feed intake. Production practices have proved that during the entire yak and bred cattle stage, feeds carry out a refined-coarse-spermic procedure, that is, during the breeding period, the cows are to be cows, goats, and cattle. ?? cattle can enhance digestive function, increase gastrointestinal volume, to provide favorable conditions for late high-yield.
Adequate feeding and sufficient high-yield feeding are enough for the cow to eat. 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.
To strengthen the milking period of dairy cows to raise milk cows during dry milk period, we should adopt the method of stopping milk to stop milking, and usually 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 rearing, lower feed costs, scientific and rational feeding purposes, is to use the lowest feed consumption in exchange for the most livestock products, that is, under the premise of ensuring the health of dairy cows, but also to fully develop the potential of dairy cows and feed efficiency .
Stepping up measures to prevent cows from infertility and prevent cows from infertility is an important measure to accelerate the breeding of dairy cows and speed up the cultivation of high-yielding dairy 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, and strengthen the dairy cow's constitution Dairy cow's insistence on reasonable exercise can help promote the cow's blood circulation and enhance the appetite of dairy cows. It can accelerate the growth and development of yaks 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.
