Abstract

There are provided a method for screening individual cattle having useful economic traits in which proteins related to the economic traits of beef cattle are identified by proteomics and are used as biomarkers, and a cattle screening kit for use in the method. The method for screening individual cattle according to the present invention includes the steps of (1) harvesting body tissue from the cattle, (2) extracting the full complement of proteins from the body tissue harvested, (3) detecting a wild-type annexin A5 protein, an isoform of the wild-type annexin A5 protein, or a modified protein of the wild-type annexin A5 protein or the isoform thereof in the full complement of proteins extracted, and (4) determining whether or not the cattle will have a high average carcass weight on the basis of the type of annexin A5 detected. The wild-type annexin A5 protein, the isoform thereof, and the modified protein thereof are detected by two-dimensional electrophoresis or an antigen-antibody reaction.

Description

technical field

[0001] The present invention relates to a cattle discrimination method for discriminating cattle with excellent economic traits such as carcass weight, the cattle to be discriminated, and a cattle discrimination kit used in the method. Background technique

[0002] At present, the breeding and improvement of beef cattle, especially the black-haired and Japanese-bred cattle, which are specialized carnivorous species peculiar to Japan, is carried out based on the statistical genetics breeding and improvement method based on the A method of estimating the heritability of cattle using the statistical genetic analysis of phenotype information and pedigree information accumulated so far as a platform. In addition, the establishment of the breeding improvement method has greatly contributed to the improvement of the heritability of Kurogewa species.

[0003] However, this statistical genetics breeding improvement method is a method of estimating the probability (pr...
