Mathematical model for evaluating fertilization abilities of landrace boars and establishing method for mathematical model

The invention discloses a mathematical model for evaluating fertilization abilities of landrace boars and an establishing method for the mathematical model. The establishing method comprises the steps of: firstly, performing data description on predictive variables of data samples of the landrace boars; secondly, performing system clustering, and dividing the landrace boars with different fertilization abilities according to sample data related with fertilization abilities of boar seminal fluids into a boar group with high fertilization ability and a boar group with low fertilization ability; and thirdly, performing discriminant analysis and Logistic regression analysis after clustering to generate a specific mathematical function. The coefficient and prediction accuracy of the mathematical model established by the method are reliable; a function model suitable for evaluating the fertilization abilities of the in-service landrace boars in Guangdong province can be provided; the function model can serve as a basis for evaluating the fertilization abilities of the landrace boars; and the mathematical model is of great significance on reduction of a gradient change interval of the fertilization abilities of the boars and accurate prediction of the fertilization abilities of the landrace boars.
