Farm cattle matching four requirements

In recent years, due to the neglect of the selection and selection of cattle, the quality of cattle has slumped, the production performance began to decline, the physical condition is poor, and the useful life is shortened. Therefore, it is of great significance to grasp the selection and selection technology of cattle and strengthen the management of breeding, in order to improve the speed and quality of farmland cultivation, and to adapt to the agricultural period. Therefore, the technical points for selecting cattle are described as follows:

First, avoid close matching

Appropriate inbreeding, although able to fix a good trait, also fixes harmful genes at the same time, resulting in decreased viability of offspring, poor adaptability, poor physical fitness and disease resistance, and poor growth and development. It may even cause stillbirths, miscarriages, and fetal malformations in pregnant cattle. In general, the male cows within three generations are related, even if the selection effect is very good, do not breed.

Second, try to avoid mating too old or too old male cows

The initial age of the grazing cattle is generally 1.5-2 years old. After 15 years old, they enter the aging period and lose their reproductive ability. When matching, it is necessary to carry out appropriate matching in accordance with the principle of “matching the prime of the prime year, and matching the youth with the young.”

Third, make full use of the advantages of hybridization

The mating of males of different breeds can show superior hybrid superiority. The yak produces fast growth, strong adaptability, easy feeding, and good serviceability. It is now easier for the people to accept the introduction of Simmental cattle to improve the local cattle.

Fourth, timely selection after matching

If you choose postpartum breeding, it should generally be carried out 60-90 days after childbirth. It is not good for cows and calves to grow too early or too late. In the affection period, the appropriate timing of cow mating is 9-24 hours after the start of oestrus.

Tetanus Antitoxin is prepared from the blood of healthy horses that have been hyperimmunized. It is recommended for use as an aid in the prevention and treatment of tetanus in animals. Each serial is tested for purity, safety, and antitoxin unitage in accordance with applicable standard requirements issued by Ministry of Agriculture and Rural Affiars of the People's Republic of China .
