Dissertation/Thesis Abstract

An evaluation of the genetic components of bovine respiratory disease and its influence on production traits
by Schneider, Matthew John, M.S., Iowa State University, 2008, 130; 1450154
Abstract (Summary)

Bovine respiratory disease (BRD) is among the most challenging infectious disease facing the entire cattle industry due to the economic consequences associated with BRD. The objectives of this study were threefold: (1) to investigate the effects of BRD incidence and number of treatments on economically important performance and carcass traits. (2) to examine the effects lung lesion scores have on important production traits (3) to evaluate the genetic components associated with BRD in both pre-wean and feedlot cattle. The healthfulness of animals is more important than ever before because of the increasing resistance to current medical treatments and prevention procedures, cost to the industry, and consumer acceptances in terms of food safety. Reducing BRD incidence would be beneficial in lowering production costs in terms of lower disease incidence and in regard to increasing performance and carcass quality from a genetic merit perspective.
