What to do with bovine follicular cysts

We know that not only humans can have problems with ovarian cysts, but cows, as a species, are also prone to further developing ovarian cysts. At this time, cystic tumors often form on the girl's ovaries due to disease, ranging from one ovarian cyst to several ovarian cysts. What to do with bovine follicular cysts?

Its diameter ranges from 1 cm to several centimeters. Bovine ovarian cysts are mainly of two types: follicular cysts and corpus luteum cysts. In addition, ovarian cysts can also manifest as endometrial cysts, including endometrial cysts and ovarian crown cysts. Mechanical therapy kneading method

This method is to hold the cystic ovary through the rectal wall and squeeze the cyst with your fingers. However, in general, when hormone treatment is ineffective or hormones are not available for a while, the squeezing method is still useful, especially for cows that are obsessed with male sex, as the cyst can be squeezed multiple times.

Puncture method

For ovarian cysts that are difficult to break by hand, you can use a needle or ovarian scalpel to puncture the cyst through the vaginal wall to release the fluid, or use a suction device to extract the cyst fluid. Hormone therapy Luteinizing hormone

The intramuscular injection dose is 100~200 international units, and the pregnant mare serum injection dose is 5000 international units. The average cure rate is about 75% per time. The estrus cycle often recovers within 20~30 days after treatment, and there is no need for repeated medication.

Progesterone

Practice has shown that the use of exogenous progesterone to treat ovarian cysts can restore sexual cycles in 60% to 70% of sick cows, and 50% can become pregnant about 45 days after treatment. The effect is more significant for sick cows with male admiration. Generally, after 2 to 3 injections of progesterone, the male admiration symptoms of sick cows will disappear, and normal estrus will be restored after 10 to 20 days, and they can become pregnant. Progesterone is more effective in long-term treatment, among which progesterone vaginal suppository is a simple treatment method. The intramuscular injection dose of progesterone is generally 50~100 mg/time. After 2~3 injections, the estrus symptoms of the cow disappear, and the estrus cycle resumes after 10~20 days. The effective rate is 60%~70%. For the recessive type, intramuscular injection of progesterone 100-150 mg and vitamin AD 10 ml, once a day, for 5 days as a course of treatment, for 2 consecutive courses, the cure rate can reach more than 90%. For the dominant type, progesterone, vitamin AD and pregnant mare serum 2000 international units are injected intramuscularly alternately, for 6 days as a course of treatment, generally 1 to 3 courses, and the cure rate can reach more than 80%.

Gonadotropin-releasing hormone

The dosage is 50-250 micrograms for intramuscular or intravenous injection, and 20 mg of luteinizing hormone-releasing hormone for intramuscular injection. Gonadotropin-releasing hormone and its analogs can cause a luteinizing hormone peak in sick cows, similar to ovulation, within 2.5 to 3 hours after treatment. It can induce and accelerate the luteinization of mature follicles in cysts or normal ovaries. After about 1 week, a luteal phase similar to the normal sexual cycle will appear. Within 30 days after treatment, about 80% of the cows will enter the normal estrus period. Within 19 to 35 days after treatment with gonadotropin-releasing hormone, more than 80% of cases are cured, and the pregnancy rate of the first insemination reaches 49% to 65%. It also has a preventive effect. Injecting this hormone into cows on the 12th to 14th day after delivery can prevent the occurrence of ovarian cysts.

Warm reminder: Bovine follicular cyst is actually a disease, and it needs to be actively treated at this time. Moreover, you can not only mechanically squeeze the girl's ovarian cyst, but you can also further use medication to treat it. At this time, you need to carefully follow the doctor's instructions to use prostaglandins
