Feeding and management of pregnant cows

Early pregnancy: because the growth of the embryo is relatively slow, it is not suitable to be overfed, but only needs to be raised according to the standard of empty period. In the middle and later stages of pregnancy: due to the accelerated growth and development of embryos, especially in the last 2-3 months, it is necessary to increase the amount of feeding and provide adequate nutrition. 1-2kg concentrate can be added to the usual food, which is conducive to promoting the healthy growth and development of embryos.

I. feeding and management of pregnant cows

1. Early pregnancy

Pregnant cows need to meet their own growth needs and embryo growth needs, as well as a good nutritional reserve for postpartum lactation. In the early stage of pregnancy, the growth of embryos is relatively slow, and the required nutrients are better. Therefore, feeding at this stage should not be too fat, generally reaching the standard of empty period, if raised too fat, it will lead to abnormal embryo development.

2. In the middle and later stages of pregnancy

In the middle and later stages of pregnancy, the growth and development of embryos will gradually accelerate, especially in the last 2-3 months, this stage needs to increase the amount of feeding, provide sufficient nutrients to promote the growth and development of embryos, in addition to normal feeding, it is also necessary to add 1-2 kg of concentrate feed every day, which can be reasonably matched according to the actual situation of the cow, but it is not suitable for overfeeding, which will easily cause dystocia.

Second, do a good job of protecting the fetus

1. Signs of miscarriage

During pregnancy, if the cow is not properly raised and managed, miscarriage will easily occur. Generally, in the early stage of pregnancy, the main signs of abortion are vaginal mucus, constantly reviewing the abdomen, and restlessness, while in the early stage of pregnancy, the main signs of abortion are breast enlargement and repeated micturition posture.

2. Raise separately

If there is abortion, it will not only reduce the litter rate in the future, but also lead to physical damage to cows, so in order to prevent the occurrence of abortion, pregnant cows and other cows need to be raised separately in the process of breeding. avoid miscarriage caused by collisions for some reason.

3. Feed fresh feed

The feed fed during the breeding period should be fresh, and should not be fed with moldy or deteriorated feed. It is also necessary to increase the amount of exercise of the cow, strengthen its own physique, and avoid the phenomenon of dystocia caused by overweight growth, but it should be noted that the amount of exercise should be controlled in the early stage of pregnancy.

III. Prevention of postpartum paralysis

1. The cause of paralysis

It is a common phenomenon that the cow is paralyzed after giving birth, which is caused by the low amount of blood calcium in the cow. If the cow is not treated in time after paralysis, it will cause great harm to the cow and can cause death in serious cases.

2. Preventive measures

In order to prevent the phenomenon of miscarriage of cows after production, preventive measures need to be taken during breeding. first of all, it is necessary to reduce the proportion of straw in the feed of pregnant cows, because during pregnancy, if a large amount of straw is fed, it is easy to cause postpartum paralysis, and feed with more calcium and phosphorus can be added in the later stage of pregnancy to meet the nutrition needs of cow growth.
