Definition of artificial insemination

Artificial insemination is the most valuable management tool for breeding by breeders. And it is a process during which bull sperm is artificially inserted into the female’s reproductive system. The main role of artificial insemination in the livestock industry is the widespread use of bulls that have genetic superiority and to a large extent is the main factor in the gradual increase in milk production of dairy cows.

However, artificial insemination requires ensuring that highly skilled techniques and management techniques are implemented to obtain proper yields. Success in the reproductive program is measured by the calving interval, which is often a function of the days between the first insemination (postpartum).

All herds have open cows at any given time (between calving and inoculation leading to pregnancy). However, cows that do not conceive at 85 days postpartum, even if the calving interval is favorable, can pose a serious economic problem.

  • Extensive use of privileged bullsSince in artificial insemination, 200,250 female cows can be fertilized with semen from a ejaculation in natural mating.
  • Reduce or eliminate sexually transmitted diseasesReduce or eliminate sexually transmitted diseases such as vibriosis and trichomoniasis through natural mating
  • Economic savingsSave on bull maintenance costs due to the low cost of artificial insemination
  • Ability to evaluate fasterFaster evaluation of young bulls using artificial insemination compared to natural mating
  • An appropriate level of crossbreedingBy using artificial insemination, we can use different sperms, even in small herds, to achieve a reasonable level of crossbreeding and thus achieve the desired breeding goals.

Signs and symptoms of estrus (sexual desire)

In order for a cow to conceive, sperm insemination must take place at an appropriate stage of the estrous cycle.
The female cow shows sexual or estrus behaviors shortly before the egg is released, at which point she attracts the male and allows him to mate.

The estrous cycle in cows begins after puberty and occurs every 21 days except during pregnancy. The estrus period in cows is the time during which the cow stands, and allows the bull or other female bull to ride, which is one of the most important factors in the reproductive management system in livestock.

During estrus, cows show symptoms that are obvious and recognizable within 18 to 20 hours.
