Methods and techniques of artificial cattle breeding
Artificial breeding is a method of breeding selected excellent cattle breeds through manual intervention and control. Reasonable artificial breeding can effectively improve the genetic quality of cattle herd and obtain better economic benefits. The following are the main methods and techniques of artificial cattle breeding:
Choosing the right time to breed:
The choice of mating timing should take into account the physiological state of the cow, which is generally carried out when the cow enters estrus. The estrus period is generally about 21 days, when the cow is in the best state of conception.
Watch for signs of heat in cows:
Cattle entering estrus will show specific behavioral signs, such as actively seeking out other cattle, vibrating their tails, restlessness, etc. Livestock pastors need to closely observe these signs to determine the estrus period and provide a basis for the right mating time.
Choose high-quality breeding cattle:
The selection of breeding cattle is crucial, and it is important to choose breeding cattle with good genetic background, high production performance, and good health. Scientific selection is carried out through genetic evaluation and relevant reproductive indicators.
Artificial insemination technology is used:
Artificial insemination is a commonly used method of artificial breeding in which frozen or fresh breeding cows** are expertly injected into the reproductive tract of the cow to achieve conception. This method can effectively control the genes and improve the reproductive effect.
Ensuring hygienic conditions:
When carrying out artificial breeding, it is necessary to ensure a hygienic operating environment to prevent the spread of infection and disease. Use disinfection tools to keep the operating site clean and ensure the hygiene of cattle and livestock workers.
Proper management of breeding records:
Record important information such as the time of breeding, the information of the breeding cattle, and the breeding of the breeding company. This helps to evaluate and manage the reproductive effect at a later stage, providing lessons for the next round of mating.
Get regular pregnancy tests:
After breeding, regular pregnancy tests are carried out to confirm that the cow is pregnant. For non-pregnant cows, re-breeding is carried out in a timely manner.
Through scientific and reasonable artificial cattle breeding methods, the genetic quality, production performance and health level of cattle herd can be improved to a certain extent, which provides strong support for the sustainable development of animal husbandry.
