Regular mating of cows with bulls is an important part of cattle keeping. Through this process, there will be no shortage of livestock, respectively, milk and meat on the farm. To sexual intercourse was successful, you need to follow a few important rules. First of all, you must be able to identify the period during which you can spend the mating. It is tame and natural. Each of these methods has its advantages and disadvantages.
When to mate
The heifers are ready for the first mating by 9-10 months, and the bulls are already 7-9 months. Despite this, the process of mating cows and bulls should not be too early, as this may adversely affect their development. Young cows will give much less milk than other individuals. Moreover, their productivity will not recover until the end of life.
That is why from 6 months of different sex animals need to be kept apart from each other. It is important to keep track of this in the pasture too, so that by chance the bull could not cover the cow. With the normal development of females and the absence of disease, the first insemination should be carried out at about 1.5 years. Do not immediately load bulls with a large number of females. For the first time, mating should occur with a maximum of 25 cows. If you increase the load, the male's health will deteriorate. Subsequently, he may lose sexual activity.
How to determine the hunting period
Bulls mate at any time after the onset of sexual activity. But the cows need to wait for the hunting period. You need to know how to determine this moment in order to lead the bull to the cows in time. During the time of hunting in females, there is a strong sexual arousal, accompanied by estrus. This period occurs every 2.5-3 weeks.
Hunting time is easy to recognize by the behavior of the cow. She is constantly in an excited state, she is very worried, moos and refuses food. In the absence of bulls, cows can jump on each other from behind and imitate sexual intercourse.
Also, the onset of hunting can be identified by inspecting the genitals of the animal. At this time, the labia become red and swell, and the vulva increases in size. Sometimes females are diagnosed with fever.
This period lasts no more than 1.5 days. Best of all, if fertilization occurs in the first half of the hunt. To be sure of the result, the intercourse of the bull with the cow is carried out twice: at the beginning of the period and after 10 hours.
Natural mating of animals
The case is natural and manual. The first option today is not very common, because it does not always lead to the desired result. If this method is used, the bull sementer must be constantly with the cows. But in this case, he can cover one female several times, which is bad for her health.
Natural mating has a big disadvantage. It is very difficult to track which cow was bullied. Sometimes he can mate with the same individual, and the rest are not fertilized. If breeding breeds are bred in a farm, it is impossible to understand which producer produced offspring. For males, natural mating also has disadvantages:
- exhaustion quickly comes;
- the term of breeding service is reduced.
During one hunting period, a bull can fertilize about 35 females. But once a week, he should rest from the process and recover his strength. In order to avoid unplanned mating of a bull and a cow at night, they should be kept separate from each other in the evening.
If natural insemination is used, animals should be regularly examined at the veterinarian to exclude all sorts of diseases.
The manual mating of cows with bulls today is practiced often. Males are kept separate from cows and run towards each other only during the period of sexual hunting. In this case, you can control when the animals mate. In the case of manual mating of cattle (cattle), the male covers no more than 200 females per year. But you need to take into account his age. The older the prizvoditel, the less chicks need to be allowed to him. In order not to harm the male, bring no more than two females to it per day. After that, it is advisable to give him rest for a day.
A cow case with a bull should be carried out indoors with a special machine. The male will be able to lean on his forelimbs. Therefore, during intercourse, its weight will be on the machine, and not on the chick.
Before mating, it is necessary to wash the genitals of the cow, then bring the bull to it. It will be excited quickly, so the process of setting will not be delayed. To be sure of successful fertilization and the subsequent appearance of the calf, the procedure must be repeated after 12 hours. Animals react sensitively to extraneous interventions and voices, so during mating in the room you need to dim the light and keep complete silence.
