Breeding instinct is one of the strongest in nature. It is this natural ability that allows all living organisms to exist in our world. Keeping a cow in his household, each person must make an animal mating. How does cows mate with bulls, the video of which you will also find in the article, will help you learn more about this process and prevent mistakes.
When is a cow ready for mating?
A pouch is an integral part of keeping a pet. However, in order for the whole process to occur correctly and successfully, you must follow the basic rules. First of all, the female and male must reach puberty. As for cows, they have puberty at the age of 8-10 months, in bulls a little earlier - by 8 months. But even at this age, the young chick is not yet ready to mate. Why?
Every owner of the cows should remember that the natural age of puberty does not coincide with the age when the animal is ready for mating. Early sexual activity adversely affects the health of both the female and the male. The animal's body should not only be ready for mating, but also for possible further bearing and the birth of offspring. Of course, this is more about female representatives, but in matings, early mating causes irreparable damage to the reproductive system.
But it is also not worthwhile to delay the first mating: productivity of females decreases, and impotence occurs in males. So, when is the best time to mate? The best age for mating in a cow is in 2 years of life, in calves - by 1.5 years. True, animals begin to show desire and sexual desire much earlier. In young heifers, the first hunt and strong arousal is observed at 10-20 months.
In order to properly make the mating, it is necessary to familiarize yourself with the basic periods and processes of the sexual cycle. Successful mating and breeding of cows depends on their flow.
The cows case should be carried out only during the hunt of the female. As for the bulls, their nature endowed them with a constant readiness for mating after reaching puberty. Therefore, let's talk about the female representatives. The state of hunting, or, so to speak, a strong sexual arousal passes periodically every 18-24 days and is accompanied by estrus.
As a rule, this period is well marked by the behavior of the animal. At this time, the cow shows anxiety, she is excited, often loses her appetite, grunts. In a herd of excited females napryagivat lay down on each other, imitating sexual intercourse with a bull.
Hunting period is also checked by inspection of the genital external organs. At this time, the vulva swells, labia lips grow and redden. Sometimes cows can increase body temperature. The whole hunting period lasts about 20-36 hours. It is best to inseminate the cow in the first half of the hunt, although today it is often done twice: immediately after the hunt is detected and after 10 hours (control insemination).
Before mating it is necessary to conduct a full inspection of animals. If there are any ailments, illnesses, the female or male is obese or exhausted, pairing can not be carried out! A cow should have a normal weight - not less than 65% of the age and pedigree norm.
To date, there are two types of mating: manual and free. Judging by the name, it is easy to understand that the manual type implies the artificial formation of pairs and the whole process takes place under the control of a person. What does it mean? With this method of mating for each particular cows pick a suitable bull. Most often, the female is tied up or held in the hands of a man.
Free mating is the closest to natural conditions and is carried out in the herd. With this method, a person cannot fully control the formation of a pair and the mating process itself, therefore, among the disadvantages of this type is the possible injury of young heifers. But, as practice shows, it is this method of mating that almost always ensures 100% fertilization.
Bull mating process
The whole process of mating a cow with a bull is fast enough. As a rule, when strongly excited, a male with good reproductive abilities quickly inseminates the female. For more details on how the process takes place, look at the video.
- Manual mating. If you are going to mate animals in this way, you need to accurately determine the period of the hunt of a cow. As a rule, specialists in farms maintain a special schedule and records estrus of females. Insemination is best done 10-12 hours after the start of the hunt. It is also important to choose the right bull for the cow. He should have not only good pedigree qualities, but also fit the female in size. Successful fertilization in this way is observed in 70% of cases, so re-insemination is often carried out.
- Natural insemination. In this case, it is enough for you to let the female and the male go for a walk together. The male himself knows when there is a period for mating, when the cow is ready for insemination. It is best to leave females and males together for 60-80 days. For young heifers it is best to choose bulls not older than 12 months. This will reduce the risk of injury to chicks.
When mating pedigreed animals, select the right pair to improve offspring and genetic qualities.
