Abstract:James Johanson, former graduate research assistant; Jeff Berger, professor of animal science Summary and Implications A multiple trait animal model was implemented to study the direct genetic and maternal genetic relationship among four traits, dystocia (DYS), perinatal mortality (PM), birth weight (BW) and gestation length(GL), expressed at the birth of a calf. The sign and magnitude of genetic correlations among calving traits demonstrates the need to use multi-trait animal models for genetic evaluation of a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
