Insulin-like growth factor-1 receptor (IGF-1R) polymorphic alleles and use of the same to identify DNA markers for reproductive longevity

摘要

Disclosed herein are embodiments for genotyping an animal for the presence of polymorphic alleles in the IGF-1R gene that are associated with reproductive longevity and/or ability to better sustain stress, and preferably selecting those animals for future breeding purposes.
