Introduction hybridization is also referred to as introduction of hybridization or improved hybridization. When a variety has many advantages, it can basically meet the needs of the development of production, but there are also individual deficiencies, and when such deficiencies are not easily corrected through the selection and breeding of this species, another species can be selected (there are many similarities between the two. The characteristic features, but not the defects that existed in the former, are crossed once with the former individuals, and then the produced hybrid males and females are bred with the mother and bull of the previous species to ensure that the former are genetically dominant. Not only does it take advantage of its strengths, it maintains its advantages, and it does not carry out fundamental transformations. We call such hybrids hybridizations.
Qinchuan cattle, for example, is a fine breed of Chinese cattle and has many advantages. However, there are also defects such as sharp cheeks, insufficient muscles in the pelvis, and low milk yield. For this reason, Qinchuan cattle can be selected within the scope of control. Consistent hair color and good adaptability, but the use of short-horned cattle or Danish Red Bull, which have relatively flat ankles and full muscles in the thigh, was introduced to hybridize them to rapidly improve the above-mentioned defects in Qinchuan cattle.
