Luteal cyst in cows: causes and symptoms, diagnosis and treatment

An ovarian cyst in a cow is one of the most common diseases that may well lead to infertility in an animal. It is cystosis that becomes the main cause of economic losses of the economy. Cysts can appear in one or both ovaries. Treatment of a luteal cyst in cows can be costly, so the disease is easier to prevent.

Appearance of disease

An ovarian cyst is a cavity filled with fluid that forms at the site of an undeveloped follicle. A cyst can occur at the very beginning of the hunt, when the body is preparing for ovulation, but it does not occur.Then the follicle overflows with fluid and grows, increasing in size and disrupting the normal sexual cycle.

Most often, the causes of luteal cysts are hormonal disorders caused by endocrine diseases - especially the hypothalamic-pituitary complex. Often neoplasms appear after the uncontrolled use of hormonal drugs or their analogues.

Contributing factors to the disease can be insufficient or unbalanced feeding, lack of essential minerals, a sharp decrease in the animal's weight, or inflammation in the uterus or ovary. It has been proven that genetic factors and predisposition may be involved in the appearance of a cyst.

Cyst symptoms

The corpus luteum is a temporary gland that forms at the site of a ruptured follicle. It is it that produces the female sex hormone - progesterone, which is responsible for the normal course of the sexual cycle in a cow, hunting and pregnancy.With any developmental pathology, the follicle tends to degenerate into a malignant cyst filled with a yellow or white liquid. Luteal cysts should be distinguished from other nonfunctional ovarian masses. A cyst appears more often in the left ovary than in the right, but it can also develop in two organs at once.

An ovarian cyst is difficult to diagnose in its early stages without an ultrasound examination due to the lack of visible symptoms. Therefore, it is recommended to carry out a preventive rectal examination of cows that come into heat irregularly, every 6-7 days.

From the general symptoms, deterioration in the quality of milk, its taste characteristics, changes in color and consistency can be distinguished. Small fat globules can be seen in the liquid. Pits form between the tail of the animal and the ischial cavities of the pelvis.The cow completely loses interest in the bull or, conversely, is overly active.

How the disease is diagnosed

A cyst at a late stage is quite well palpable through the rectum, but it can be confused with other formations due to the subjectivity of sensations. Ultrasound scanning is considered a much more reliable research method. In addition, milk analysis is carried out. If an increased content of progesterone is found in the fluid, this is a reason to think about the presence of neoplasms in the ovary.

Cattle treatment methods

Before treating an animal, you need to try to balance the diet, otherwise the pathology will return again after an indefinite time. To do this, pulp and other fatty concentrates are excluded from the herd's diet, more vitamins, fruits and vegetables are added. In the summer - a lot of green fodder. Sick cows are isolated in clean stalls with plenty of bedding, which is cleaned and disinfected every day.The temperature in the barn is at least 7 degrees Celsius.

Follicular cysts

With follicular formation in the blood, the concentration of estrogens rises sharply. Drug treatment is most often used, especially if the disease has not gone too far.

To do this, a course of hormonal drugs is prescribed in combination with fatty acids, which increase the likelihood of hunting. They are also prescribed after surgery.

"Luteostenol" acts gradually, so you can not enter several servings of the drug at once. The average course of treatment is 7-14 days. It has biological activity and temporarily stimulates the production of sex hormones. The first signs of heat in a cow will appear within a few days after the first injection of the drug.

All of the above drugs can be administered to cows only after prior consultation with a veterinarian and after an accurate diagnosis. The wrong treatment can only aggravate the situation, and the farmer risks losing a large part of the livestock.

Luteal cysts

In the treatment of luteal cyst since the early 2010s, hormonal drugs such as Gonadorelin, Surfagon and Estrofan have been used, which promote the resorption of luteal tissue and the onset of sexual desire after 21-30 days.

All drugs are based on natural hormones, so they do not cause rejection by the body or an allergic reaction.

Can be used on cows of any age. Before prescribing any medication, you should consult your doctor, because the symptoms of a cyst can easily be confused with metritis, mastitis and other disorders in the body.

Prevention

Cattle luteal cysts cause huge economic damage to the economy. It is much easier and cheaper to prevent the onset of a disease than to cure it. To do this, they provide the livestock with the right conditions for keeping - a warm and clean barn, regular walking and green fodder in the summer.

Don't give too much fatty food, such as bagasse. It is better that a livestock specialist or other farm worker draw up a diet individually for each cow. Animals that are predisposed to degeneration of the ovary are not allowed to breed, and the resulting young animals are sold for milk production or for meat.
