Simmental hybrid cattle breeding, screening and evaluating method

The invention discloses a breeding, screening and evaluating method for Simmental hybrid cattle, and relates to the technical field of livestock breeding. Screening cattle from cattle herds, and constructing a breeding male parent group and a breeding female parent group; acquiring character information of the breeding male parent group and the breeding female parent group, and analyzing genetic probabilities of high-contribution-rate characters and low-contribution-rate characters of individual cattle; according to the obtained genetic probabilities, predicting the genetic probabilities of the individual cattle in the breeding male parent group with the breeding female parent, the first filial generation, the second filial generation,..., and the nth filial generation, and establishing a database; establishing an evaluation model, and evaluating scores of offspring generated by combination of the male parent, the breeding female parent and the n generations according to genetic probability and character info
