Introduction of beef cattle

Purebred breeding is also called breeding of this species. It refers to the method of continuously improving the herd quality and its production performance through selection, breeding and breeding in cattle breeds. Many beef breeds in foreign countries and many local cattle seeds in China are cultivated through this method. The existing breeds of beef cattle still need to continue to implement a purebred breeding system to increase the efficiency of beef cattle production. In the beef cattle industry, it is still necessary to rely on purebred breeding to provide breeding cattle and a large number of shelf cattle for fattening. (1) The breeding conditions for purebred breeding are generally selected for purebred breeding. 1. Local varieties of meat The variety has a relatively uniform body appearance and high production performance, and has a stable heredity. In order to further improve its production performance and promote its uniform appearance, it is necessary to use pure breeding methods to consolidate and improve the characteristics of certain good traits. This method is also known as seed breeding. Such as China's excellent local breeds Qinchuan cattle, Nanyang cattle, Jinnan cattle, Luxi cattle, Yanbian cattle, Fuzhou cattle, Pixian Red Bull and Bohai Black cattle. Through thoroughbred breeding, we will gradually correct some shortcomings in the appearance structure and improve its production performance. 2. Beef breeder breeds This breed has been cultivated by people to make it a specialized beef breed with high meat production and stable heredity. In order to increase the number of groups, maintain the characteristics of varieties, and constantly improve the quality, it is necessary to plan a thoroughbred breeding. Such as foreign beef breeds such as Charolais, Limousin, Angus, Piedmont, Simmental, Hereford, and Shorthorn. All need to adopt the method of pure breeding, maintain pure breeding, expand the population for promotion and cross breeding needs. 3. Local breeds of meat have low economic value and cannot fully meet people's needs, but certain traits and characteristics, such as adaptability to the environment, disease resistance, resistance to roughage, and certain aspects of production performance, are certain or prominent. Advantages, which need to retain the necessary amount in a certain area, as a gene bank for cross breeding. This method is also called preservation seed breeding. 4. After the crossbred hybrid has entered the cross-fixation stage, it needs a purposeful selection and selection of the seed, and the good quality of the cross-breeding is fixed so that the quality of the whole group is further improved and tends to be neat. Although the breeding work at this stage is not conducted within a variety, it can be similar to the method of breeding within a variety. This breeding method is also called self-breeding. (B), pure breeding breeding group rhyme mating way it mainly includes kinship breeding (inbreeding) and crystal breeding two aspects. Affinity breeding: Affinity breeding refers to the mating group of related male cows. Inbreeding is also called inbreeding. Parameters that reflect the degree of closeness are inbreeding coefficients and kinship coefficients. The inbreeding coefficient is a measure of the decrease in the proportion of heterozygous genes. Phylogenetic breeding can not only purify certain good genes, but also expose some recessive genes that are homozygous and reveal themselves as bad traits and become unhealthy individuals, resulting in smaller body size, weaker constitution, reduced production performance, and malformed development. The method of preventing inbreeding recession is as follows: First, inbreeding is performed only once or twice, then mating with a relative or relative in order to maintain its good traits; Second, strict selection is made to prevent mating of males with common defects; It is the poor individuals who have eliminated those mutant and recombined homozygous inferior genotypes. Breeding: It is the advanced stage of breeding work. It is a breeding method commonly used in pure breeding. It is characterized by the purpose of cultivating differences in the type of herd in order to continue to maintain and expand the beneficial traits of the herd to future generations. Individuals or groups that will stand out in a certain area will be able to maintain the good traits in this area with homogenous matching methods. Using this method, a number of strains are established within a variety. Each strain has its own characteristics. After the combination (crossing) of crystal systems, the whole herd can be improved in many ways.
