Partitioning Variation In Measurements Of Beef Carcass Traits Made Using Ultrasound, Bradie M. Schmidt
Partitioning Variation In Measurements Of Beef Carcass Traits Made Using Ultrasound, Bradie M. Schmidt
Electronic Theses and Dissertations
Ultrasound technology provides cattle breeders a relatively quick, non-invasive, and economical way to gather carcass data on live animals. Ultrasound provides the means to accurately predict body composition and develop estimated breeding values; however, national cattle genetic evaluations assume homogenous additive genetic and residual variances. These assumptions may be violated when estimating genetic merit for carcass traits by ultrasound because of differences in variance due to scanning technician and image interpretation laboratory. The objective of this study was to partition the phenotypic variance of measurements of carcass traits that were made using ultrasound into components attributable to additive genetic effects, …
Impact Of Postweaning Management Strategies On Beef Carcass Characteristics And Meat Quality, Christina Elaine Bakker
Impact Of Postweaning Management Strategies On Beef Carcass Characteristics And Meat Quality, Christina Elaine Bakker
Electronic Theses and Dissertations
The overall objective of this dissertation was to determine the impact of selected post weaning management strategies on beef carcass characteristics and meat quality. The specific objectives were 1) determine the effect of a rumen-protected long chain fatty acids fed during finishing on live performance, serum fatty acid profile, carcass traits, and predicted carcass composition, and 2) determine effects of feeding brassica-based cover crops to cattle during backgrounding on live animal performance, carcass characteristics, tenderness, juiciness, and flavor of strip steaks, and case life of ground beef and strip steaks. Results from both objectives indicate post weaning management strategies do …
