What are the treatment methods for infertility after breeding in dairy cows?

The reproduction of dairy cows is now highly valued in production and has a great impact in the production process of farms. Many farmers suffer significant economic losses because their cows cannot be bred, which greatly reduces the reproduction rate of dairy cows. Therefore, doing a good job in dairy cow breeding is very important work. So below, Shuaishuai will explain to everyone how to treat it!

I. Symptoms

The manifestation of infertility is dairy cows that have been bred during three consecutive estrus periods but still have not successfully conceived. This phenomenon belongs to cows that remain infertile after repeated breeding. In general, its causes are closely related to the secretion of some reproductive hormones and uterine diseases. In addition, some symptoms include overt endometritis, follicular cysts and luteal insufficiency, etc.

II. Treatment

1. Endometritis

This is an inflammation of the uterus, and its incidence is also relatively high. It generally causes early embryonic death, or miscarriage before calving, and the conception rate is very low. This disease cannot be delayed; the longer it is delayed, the harder it is to treat. If it is delayed to the late stage, almost all ordinary drugs are useless. Therefore, this disease has caused economic losses for many farmers, and in severe cases it can even endanger life.

Treatment methods: Overt endometritis: inject cloprostenol and estrogen intramuscularly. During estrus, pour heated iodine solution into the uterus, then use some antibiotics and chlortetracycline. One course of treatment is enough, and breeding cannot be carried out during this period. Hidden endometritis: generally no obvious symptoms can be seen, but it easily causes miscarriage. The best treatment time is during estrus, when the inflammatory substances in the uterus can be discharged smoothly. Then pour in iodine solution, and some oxytocin and ergometrine can be injected. Next, give antibiotics and chlortetracycline, similar to the overt type.

2. Follicular cysts

Follicular cysts are caused by insufficient secretion of lutein in the body. This disease can lead to phenomena such as failure to ovulate in dairy cows and degeneration and death of egg cells. The cause is mainly reproductive hormone disorders or some reproductive diseases. Progesterone can be used for intramuscular injection. After about twenty days, estrus generally occurs. At this time, the conception rate of breeding is the same as normal, but the cyst must be able to be squeezed and broken, the uterus must have no inflammation, and it must be induced by nutritional factors.

3. Luteal insufficiency

This disease is caused by improper feeding and management. Poor nutritional supply makes the dairy cow's physique worse, and insufficient secretion of progesterone leads to early embryonic death and miscarriage. Chorionic gonadotropin and dexamethasone can be injected when the dairy cow is in estrus, which can achieve a therapeutic effect.

The above are the treatment methods for infertility after breeding in dairy cows. Have you all learned them? I hope this article can help everyone.
