An overview of beef cattle improvement programs in the United States.
A periodic review of beef improvement programs is useful as a benchmark and as an opportunity to reevaluate industry direction. The history of improvement programs is reviewed with particular emphasis on recording organizations, program financing, and technological progress. The various breed associations have become the primary suppliers of performance programs, which are largely funded through registration income. Current practices are described from the aspects of traits recorded and delivery systems to collect, analyze, and distribute the data. The unique or innovative features of several breed made of the organization, technical, and educational challenges facing beef improvement. Although increased participation in genetic improvement programs is expected, substantial efforts are needed to serve adequately the needs of a changing beef cattle industry.
