Bloody discharge that appears in a cow after insemination can be completely safe from the point of view of diseases. But often this is a sign of endometritis or early abortion.
Why does a cow bleed after insemination?
To correctly determine the cause, you need to take into account the time at which bloody discharge appears in the cow after covering. During estrus, it is normal for queens to notice mucus in the vulva before ovulation. Although not always. Sometimes mucous discharge appears only on the day the egg is released. Likewise, there may or may not be bloody marks in the vulva. Moreover, the probability, as in the famous joke about a dinosaur, is 50%. It all depends on the amount of hormones in the cow’s body and the strength of its capillaries in the uterine mucosa.
Sometimes a cow may start bleeding after artificial insemination. This is not a problem if the inseminator just slightly scratched the cervix.
So spotting can appear for various reasons:
- “over-walked”;
- capillaries burst;
- damage to the mucous membrane during mating or artificial insemination;
- early miscarriage;
- endometritis.
The latter is a consequence of a previous unsuccessful calving. Before inseminating such an individual again, it is necessary to treat it.
Is bleeding in a cow after insemination dangerous?
The appearance of blood is not dangerous, provided there is only a small amount of it. But there is an interesting feature here. All cows are divided into 2 types:
- there is no bleeding if the cow has walked and become pregnant;
- they exist regardless of the success of insemination.
In the first type of animal, upon successful fertilization, clear or yellowish mucus is secreted. It indicates that the egg has implanted in the uterus.
But since the owner usually does not look under the queen’s tail every minute, a small amount of blood may go unnoticed. Also, not everyone will perceive a small red line in the mucus as bleeding. And in fact, this is what it is.
The second type will have blood in any case, and by the time of its appearance you can even tell how successful the insemination could have been.
In “bleeding” cows, such discharge appears 2-3 days after the heat, regardless of fertilization. But if insemination was carried out on time, bloody mucus will appear on the 2nd day after the procedure. The probability of pregnancy is maximum.
The appearance of bloody mucus on or before the day of insemination means that the timing has been missed. The egg is old. Pregnancy is possible, but the embryo is likely to be weak and nonviable. Fertilization at this stage often ends in early abortion.
Bloody mucus on the 3rd day after the inseminator’s work means that the procedure was carried out too early. As with delayed fertilization, the likelihood of pregnancy is low.
The only time the appearance of blood in mucus is dangerous is after a few days. Fertilization success is usually determined by rectal examination 3 weeks after heat. The appearance of bloody discharge in a pregnant cow means miscarriage at an early stage.
Abortion may be a sign of a serious illness. Therefore, with early abortion, it is better to invite a veterinarian and examine the animal.
What to do if a cow bled after insemination
Normally, if there is blood after insemination, nothing needs to be done. Often this is only damage due to rough human work. Although it must be taken into account that it is precisely such small wounds of the capillaries that are a wide open gate for sexually transmitted infections. If the insemination deadlines are overdue, the procedure will have to be repeated in the next cycle.
Preventive actions
Special prevention is not required unless we are talking about preventing early abortions. Besides the abundant ones. A large amount of blood means that the uterus does not have enough calcium or vitamin D. Prevention consists of replenishing these elements and revising the diet to increase the necessary substances.
Conclusion
A cow does not always experience spotting after insemination, and the reasons for its appearance are different. Regardless of what type a particular individual belongs to, pregnancy testing should always be carried out 3-4 weeks after the expected fertilization.
