In a cow after a bull, white discharge occurs in two cases: flowing semen or vaginitis. There may also be bloody (brown) mucus if endometritis develops. Often "white" is called the usual transparent physiological outflow during and after the hunt. In fact, they are yellowish in color. Such liberties in terminology introduce significant confusion in understanding whether a cow's discharge is normal or a disease.
Why does a cow have white discharge after covering?
Normal physiological discharge from the vulva in a cow is clear and yellowish. The appearance of a different color and clouding of mucus indicates the presence of inflammatory processes in the animal's reproductive system. Usually, these diseases develop after calving. After mating with a bull, inflammation can begin only if the uterine lining has been damaged and an infection has entered the body.
With natural mating with a bull, cervicitis may develop due to damage to the muscular or mucous membranes of the cervical canal. In this case, the appearance of purulent outflows from the vulva is not excluded. In this case, the appearance of the external genital organs will be far from normal. In particular, the mucous membrane will be swollen.
Colpitis
It is believed that white discharge occurs with vaginitis. This is not entirely true. Colpitis, which is the "classic" vaginitis, is characterized by vesicles on the mucous membrane of the genitals. This is an inflammation of the vaginal mucosa. It is often the result of other problems in the reproductive system:
- cervititis;
- endometritis;
- trichomoniasis;
- campylobacteriosis;
- birth canal injuries.
In all cases, vesicles are formed on the vaginal mucosa, filled with one or another type of exudate. The latter depends on the cause of the vaginitis.
Another picture is observed with vestibulovaginitis. The nature of mucous secretions is very diverse here.
Such white mucus is possible with purulent vestibulovaginitis.
Vestibulovaginitis
Such white mucus is possible with purulent vestibulovaginitis.
The difference from vaginitis is that in this case, the mucous membrane of the vestibule becomes inflamed. However, later the inflammation passes to the vagina itself. Vestibulovaginitis is divided according to three criteria: course, nature and origin.
In the course of the disease, they are divided into acute and chronic. By the nature of the process, they are:
- purulent;
- serous;
- catarrhal;
- phlegmonous;
- diphtheria;
- mixed.
By origin, three groups are distinguished: non-infectious, infectious and invasive.
The causes of the disease can be:
- traumatic, for example, when mating with a bull;
- infectious when infected with sexually transmitted pathogenic microflora;
- complication after infectious diseases.
Discharge will be with any vestibulovaginitis, but not always they will be white or yellow. In acute serous form, the exudate will be almost transparent. In acute catarrhal inflammation, the mucus is cloudy and viscous. Acute purulent is characterized by outflows of white, yellow and yellow-brown color. Possibly greenish too. Pus has a strong, unpleasant odor.
With an acute phlegmonous form, there is little pus; it dries up at the base of the tail.Putrid brown liquid is secreted in acute diphtheria vestibulovaginitis.
In terms of volume, the exudate is most similar to the usual physiological mucus in purulent-catarrhal and chronic catarrhal vestibulovaginitis. The difference is in the admixture of pus. The discharge itself can be both liquid and thick.
Why does a cow have yellow discharge after insemination?
With a high degree of probability, yellow discharge appears with endometritis. This is an inflammation of the lining of the uterus, usually occurring as a complication of difficult calving. As a result, by the time of mating with a bull, the disease has time to go far enough for the exudate to acquire a yellow, or even brown color from admixture of blood.
Discharge with endometritis can also be mucous. The nature of the outflow depends on the form of the disease: catarrhal, purulent or fibrinous. In the first, mucus is released, in the second, pus, in the third, fibrin films are present in the mucus.
In all cases, the most dangerous is pus with clotted blood. Such outflows will appear dark yellow or brownish. This color means that the inflammation has reached the blood vessels and damaged them.
With fibrinous endometritis, the discharge can be not only brown, but also clearly bloody, with purulent white opaque mucus flows from the uterus
What to do if a cow has a discharge after a bull
In this case, the actions directly depend on the appearance and timing of the discharge. If a cow starts to leak thick white liquid from the vulva right after natural mating with a bull, most likely you should not worry. No infection develops that quickly. Provided that the animal was healthy before insemination. But in the first 15 minutes, bull sperm can flow from the vagina of the uterus.
In the presence of diseases of the reproductive organs, the discharge will be "colored".
Nature is a big reinsurer. The portion of ejaculate that the bull throws out during mating would be enough to inseminate hundreds of queens. Excess sperm is either gradually absorbed by the female's body, or flows out.
The second option: transparent, thick and sticky mucus, which appears 2-3 days after mating with a bull or insemination. The duration of such discharge is from a month to two. They indicate that the cow has fertilized.
This discharge stops after 1-2 months. But to be sure that the cow is pregnant, it must be examined rectally a month after mating.
The appearance of cloudy discharge 1 or more days after mating indicates the development of an inflammatory process. In this case, it is necessary to start treating the cow. But usually all diseases of the uterus and vagina develop after calving as a complication. White, yellow and brown discharge before mating with a bull can be in a cow only if the owner of the animal did not pay attention to the onset and development of the disease.
But this happens already 9 months after the fertilization of the animal with a bull. And the mucus is not white, but yellowish. May be slightly cloudy. It begins to stand out about 2 weeks before calving.
Such abundant cloudy discharge is not the norm under any circumstances and is highly likely to indicate advanced endometritis.
Treatment
With colpitis, the cow's vagina is irrigated with disinfectant solutions:
- soda;
- hydrogen peroxide;
- furacilin;
- rivanola.
In case of severe damage, tampons with disinfecting ointments are introduced into the vagina: streptocidal, Vishnevsky, ichthyol and others like them.
With cervicitis, the cow's vagina is irrigated with a solution of Lugol or potassium permanganate, after which the exudate is removed and, using a tampon, the cervical canal is lubricated with ichthyol or iodoform-tar ointment.
Treatment of vestibulovaginitis depends on their type. In case of serous, catarrhal and purulent inflammation, the cow's vagina is doused with a solution of furacilin, ethacridine lactate or 2% baking soda solution. Next, antiseptic liniment is applied to the mucous membranes: syntomycin, streptocide, Vishnevsky. With phlegmonous and diphtheria, washing is similar, but 1% novocaine in powder is added to the liniment.
With endometritis, the animal is placed in improved housing conditions. In the uterus of a cow, 50 ml of a 2% cold vagotil solution or 500 ml of Lugol's solution are injected. After that, the contents of the uterus are evacuated with a vacuum pump and antimicrobial boluses are placed inside the cow. Neurotropic drugs, vitamin A and ergot derivatives are injected subcutaneously. The Mosin blockade is also used. General therapy means are shown.
Preventive actions
Normal physiological secretions, indicating the likelihood of fertilization, often adhere to the tail of the cow and attract flies. To avoid infection of the genitals after mating with a bull, it is necessary to observe the hygiene of the external genital organs: the vulva and tail are washed daily with warm water and wiped dry. At the same time, the owner can make sure that there are no problems or notice the disease in time.
For the prevention of gynecological problems in a cow, it is necessary to observe the conditions of housing and feeding. The predisposition to endometritis is often aggravated by a lack of vitamins and lack of exercise, which reduce the animal's immunity.
Conclusion
In a cow after a bull, white discharge should ideally be absent altogether, if this is not the very first minutes after mating. In a healthy uterus, mucus should be transparent both after mating and before calving.
