Association of a corticotropin-releasing hormone receptor 2 (CRHR2) polymorphism with carcass merit, meat quality, and stress response traits in pigs

A single-nucleotide polymorphism within the corticotropin-releasing hormone receptor 2 (CRHR2) gene was identified and evaluated in two pig populations. The CRHR2 genotype was significantly associated with nine carcass and meat quality traits in the F2 resource population and exhibited a suggestive association with the stress response trait blotching in the halothane challenge population.
