I. symptoms of illness

The performance of infertility is reflected in cows that have been mated in three consecutive periods of estrus but have not been successfully conceived. This phenomenon belongs to long-term infertile cattle, which is generally caused by the secretion of some reproductive hormones and uterine diseases. In addition, some symptoms are suffering from dominant endometritis, follicular cysts and luteal insufficiency.

II. Treatment

1. Endometritis

This is a kind of inflammation of the uterus, and its incidence is also relatively high. it will generally cause the embryo to die at the early stage, or miscarriage before delivery, and the pregnancy rate is very low. The disease cannot be delayed, and the more it drags on, the more difficult it is to treat. If it is dragged on to the late stage, almost ordinary drugs are useless, so this disease has caused economic losses to many farmers, and serious ones will endanger lives.

Treatment: dominant endometritis: intramuscular injection of chloroprostol and estrogen. In estrus, the heated iodine solution is infused into the uterus, and then some antibiotics and chlortetracycline are used. After a course of treatment, no mating can be carried out during this period. Invisible endometritis: this generally does not show obvious symptoms, but it is easy to cause miscarriage. the best time for treatment is during estrus, when the inflammation in the uterus can be smoothly excreted, and then the iodine solution can be infused. You can inject some oxytocin and ergoxin, and give it antibiotics and chlortetracycline, similar to dominance.

2. Follicular cyst

Follicular cysts are caused by insufficient lutein secretion in the body, which can lead to anovulation, egg degeneration and death in dairy cows, which is mainly caused by reproductive hormone disorders or some reproductive diseases. Progesterone can be used for intramuscular injection, and estrus will generally occur after 20 days, when the pregnancy rate of mating is the same as normal, but the cyst must be crushed and there is no inflammation in the uterus, which is induced by nutritional factors.

3. Luteal insufficiency

This disease is caused by improper feeding and management, nutrition and supply of tea, which deteriorates the physique of dairy cows, and insufficient secretion of progesterone leads to early embryo death and miscarriage. Chorionic gonadotropin and dexamethasone can be injected into cows during estrus, which can achieve the effect of treatment.
