Genetic Research Used to Tackle Disease Susceptibility in Feedlot Cattle

Research project: "The Genetics of Feedlot Health"

The economics of cattle health problems to the industry is staggering. Due to the enormous potential value, a study was developed employing both molecular and quantitative techniques to characterize and improve feedlot health.

The two objectives of this research include:

  • Develop methods of identifying animals that are genetically superior for feedlot health characteristics through the use of both molecular and quantitative techniques
  • Identify new traits associated with feedlot health that may improve accuracy of selection for disease resistance

In 2007 and 2008, a variety of data has been collected from steers at the Five Rivers Cattle Feeding in Lamar, CO, including:

  • Complete health records
  • Feed ration, carcass and ultrasound data
  • Animal performance and temperament
  • Weather and environmental conditions

This research project is sponsored by Pfizer Animal Genetics, the global livestock genomics business unit of Pfizer Animal Health.
