Selection method capable of simultaneously improving feed efficiency and increasing growth speed of pigs

The invention relates to a selection method capable of simultaneously improving feed efficiency and increasing growth speed of pigs. The selection method is characterized in that the selection methodfor simultaneously improving the feed efficiency and increasing growth speed of pigs by utilizing over-growth body weight traits comprises the steps of selection of basic conditions, determination ofindexes and data processing, breeding value estimation, comprehensive selection index calculation, and reserve breeding pig selection, matching and verification. The selection method is simple and practical, is good in selection effect, can be used for phenotypic selection of simultaneous determination groups, can be used for comparing and selecting different determination groups according to heritability and genetic correlation, and can be used for directly selectively improving the feed efficiency and increasing the growth speed of pig groups. 本发明涉及一种能同时提高猪饲料效率和生长速度的选择方法，其特征在于：利用超增长体重性状同时提高猪饲料效率和生长速度的选择方法，包括选择的基本条件、测
