dc.description.abstractIt has been suggested that traits of fertility have the single largest economic impact for cow-calf producers. Many traits of fertility are threshold traits, which are observed on a discrete scale. Stayability has been reported as a measure of sustained reproductive ability which is measured on a discrete basis. For reproductive traits, several analyses with field data have shown very small differences between the threshold and the linear model. Therefore, the objective of this study was to investigate the use of linear and threshold models to estimate heritability and trends for Stayability in beef cattle. Data reported to the American Hereford Association were used in this study.
