Feedyard Managers and Veterinarian Response to a Delphi Feedyard Biosecurity Survey
American Association of Bovine Practitioners Conference Proceedings, 2006 Biosecurity is an important aspect of disease prevention in any agricultural production system. The beef feedyard is particularly vulnerable to disease introduction because of the large number of different cattle arriving from multiple sources. Additionally, the large concentration of animals makes a feedyard a likely target for bioterrorism from ...

Nitrous Oxide Emissions from Open‐Lot Cattle Feedyards: A Review
Journal of Environmental Quality, Volume 45, Issue 6, Page 1797-1811, November-December 2016., 2016 Nitrous oxide (N2O) emissions from concentrated animal feeding operations, including cattle feedyards, have become an important research topic. However, there are limitations to current measurement techniques, uncertainty in the magnitude of feedyard N2O fluxes, and a lack of effective mitigation methods.
