METHOD OF PREDICTING ANIMAL LITTER SIZE USING PROTEIN BIOMARKERS RELATED WITH FERTILITY, AND METHOD OF PREDICTING ANIMAL SPERM QUALITY AND LITTER SIZE USING CHLORTETRACYCLINE STAINING

摘要

The present invention relates to a method of predicting animal litter size using a fertility-related protein marker, and more particularly, to the discovery of a sperm marker that is expressed differently depending on animal fertility, a marker composition for predicting litter size, which comprises an antibody that binds specifically to the marker, and a method of predicting animal litter size using the marker composition. Moreover, the present invention relates to a method of predicting animal semen quality and litter size by chlortetracycline staining, and more particularly, to a method of predicting of animal litter size by measuring the motility, motion kinematics or capacitation status of sperm. When the animal sperm-derived protein marker according to the present invention is used, the litter size of individuals can be predicted by analyzing a protein that is expressed differently depending on litter size. When the method of animal semen quality and litter size by chlortetracycline staining is used, the fertility of sperm and the litter size of individuals can be predicted. According to the present invention, superior species having high sperm fertility and high litter size can be selected based on information provided by the method. Thus, the present invention is highly useful for the sustainable production of animals.
