Estimates of Genetic Parameters for Calving Performance from Designed Selection Studies Johanson, James Berger, P. 2018-08-25T21:43:16.000 2020-06-29T23:30:18Z 2020-06-29T23:30:18Z Mon Jan 01 00:00:00 UTC 2007 2007-01-01
dc.description.abstract <p>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 animals for calving performance. Adequate information exists to begin developing a calving performance index. This index will enable breeders of dairy cattle to optimize the health and well-being of replacement animals and reduce the incidence of dystocia and perinatal mortality.</p>
