Method for screening cattle, cattle screened, and cattle screening kit

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.
