Abstract
The present invention discloses a selection method to improve the egg production rate in the poultry, the method comprises step of collecting the protein samples and the related egg production information, transforming to the scores and the ranks of the protein samples and the corresponding codes, the following step is to combine the corresponding codes to regional codes and comparing the matching rate; and selecting the poultry with improved egg production. The present invention further provides another method comprising collecting and ranking the protein samples and the related egg production information of the known and unknown groups to obtain the values, selecting a poultry having desired egg production from the known group, defining regional codes based on the values of the known group, comparing the values between the known and unknown groups, and selecting the poultry with improved egg production according to the matching rate after comparing.
