The spotting that appears in a cow after insemination can be completely harmless from the point of view of diseases. But often this is a sign of endometritis or early abortion.
Why does a cow have bleeding after insemination?
To correctly determine the cause, the timing of the appearance of spotting in the cow after covering must be considered. When hunting normally, mucus can be seen in the vulva in the uterus before ovulation. Although not always. Sometimes mucous outflows appear 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 well-known anecdote about a dinosaur, is 50%. It all depends on the amount of hormones in the body of the cow and the strength of its capillaries in the uterine lining.
Sometimes a cow's bleeding appears after artificial insemination. This is not a problem if the inseminator just scratches the cervix slightly.
So spotting can appear for various reasons:
- "Went overboard";
- 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 must be treated.
Blood in small quantities does not pose a danger to the health of the uterus
Is bleeding in a cow dangerous after insemination?
The appearance of blood is not dangerous, provided that there is not much 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 fertilized;
- they exist regardless of the success of insemination.
In the first type of animals, upon successful fertilization, transparent or yellowish mucus is secreted. She indicates that the egg is anchored in the uterus.
But since the owner usually does not look under the tail of the uterus every minute, a small amount of blood may go unnoticed. Also, not everyone will perceive the small red line in the mucus for bloody discharge. And in fact, this is it.
The second type will have blood in any case, and by the time of its appearance, one can even say how successfully insemination could have gone.
In "bloody" cows, such discharge appears 2-3 days after the hunt, 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 dates have been missed. The ovum is old. Pregnancy is possible, but the embryo is likely to be weak and unviable. Fertilization at this stage often results in early abortion.
Bloody mucus on the 3rd day after the work of the inseminator means that the procedure was carried out too early. As with delayed fertilization, the likelihood of pregnancy is low.
The only case when the appearance of blood in the mucus is dangerous is after a few days. Fertilization success is usually determined by rectal examination 3 weeks after heat. The appearance of spotting in a pregnant cow means an early miscarriage.
Abortion can be a sign of a serious medical condition. Therefore, with an early abortion, it is better to invite a veterinarian and examine the animal.
Modern methods make it possible to determine the presence of pregnancy with a high degree of accuracy.
What to do if a cow blots after insemination
Normally, with blood after insemination, nothing needs to be done. Often this is just damage due to the rough work of a person. Although it must be borne in mind that it is precisely such small wounds of the capillaries that are wide-open gates for sexually transmitted infections. If the timing of insemination was overdue, the procedure will have to be repeated in the next cycle.
Preventive actions
Special prevention is not required if it is not about preventing early abortion. Except for the abundant ones. A large amount of blood means that there is not enough calcium or vitamin D in the body of the uterus. Prevention consists in replenishing these elements and revising the diet in the direction of increasing the necessary substances.
Conclusion
In a cow after insemination, spotting does not always occur, and the reasons for their appearance are different. Regardless of what type a particular individual belongs to, a pregnancy check should always be carried out 3-4 weeks after the intended fertilization.
