Abstract
The purpose of this article is to discuss the host as a cause of infectious bovine keratoconjunctivitis (IBK). The focus is on the host genetics rather than characteristics of the host, such as age, sex, and season of birth. From 4 conducted studies, estimates of IBK heritability are generally less than 0.15, except for some estimates for Herefords and Angus cattle around 0.2 and 1 study reporting a heritability of 0.33. These magnitudes of heritability are typically described as low to moderate. Quantitative trait locus on chromosome 1, 2, 12, 13, 20, and 21 has been associated with IBK resistance.
