Feeding and management techniques of cows during pregnancy

The cow is the basis of the development of a farm, and the importance of the farm can be imagined. It is necessary to meet the nutritional needs of the cow during pregnancy in order to make it produce high-quality calves and recover quickly after delivery. The following pro-agricultural network brings the feeding and management techniques of cows during pregnancy, let's take a look.

1. Feeding management

After the cow is pregnant, the intake of nutrients is not only to meet their own growth, but also to meet the needs of embryonic growth and postpartum lactation preparation, to make a good nutritional reserve. In the early stage of pregnancy, the growth of the embryo is relatively slow, and the nutrients needed are better, so the feeding at this time should be careful not to be too fat, as long as it reaches the standard of empty period, if it is too fat, it will lead to abnormal embryo development. In the second and second trimester of pregnancy, the growth and development of embryos began to accelerate, especially in the last 2-3 months, when it was necessary to increase the amount of feeding and improve sufficient nutrients to ensure the growth and development of embryos. In addition to normal feeding, 1-2kg of fine feeding was needed every day, which should be matched reasonably according to the actual situation of cows, but to avoid excessive feeding, it was easy to cause dystocia.

2. Do a good job of protecting the fetus

If the cow is not properly fed and managed during pregnancy, it is extremely prone to miscarriage. Generally, mucus will flow out of the vagina before the early pregnancy, constantly reviewing the abdomen and restlessness; while the precursor of miscarriage after the early pregnancy is mammary gland enlargement and repeated micturition posture. Once the abortion occurs, it will not only affect the future birth rate, but also cause harm to the cow's body. Therefore, in order to avoid the occurrence of this phenomenon, pregnant cows should be raised separately from other cows to avoid abortion caused by collisions for some reasons. in addition, the feed must be fresh, do not feed spoiled or moldy feed, and strengthen the amount of exercise of the cows. strengthen the physique, avoid overweight, dystocia, but it should be noted that the amount of exercise should be controlled in the early stage of pregnancy.

3. Prevention of postpartum paralysis

Postpartum paralysis of the cow is a common phenomenon, which is caused by the low amount of blood calcium in the cow. Once the cow is paralyzed, it will do great harm to the cow and cause death in serious cases. Therefore, in order to prevent this phenomenon in postpartum cows, preventive measures must be taken, the first thing to do is to reduce the proportion of straw in the feed of pregnant cows, according to the actual breeding experience, feeding a large amount of straw during pregnancy can easily lead to postpartum paralysis, and then appropriately increase more calcium and phosphorus feed in the late pregnancy to meet the cow's needs for them.
