Feedlot Health Management Services is a comprehensive beef industry consultancy, providing veterinary services, herd health programs and computerized health-recording systems and other informational tools to producers. Fat yield, lean yield, meat tenderness, carcass marbling and carcass grading are some characteristics of cattle that are measures of beef quality. Thus, the goal of this project is to determine how these characteristics and the genetic makeup of the cattle are correlated with one another. If there are associations with these traits and the DNA of the cattle within specific genes known to be associated with beef quality, management decisions can be made to increase the quality of beef that is produced.
