Summary of BRD data from the 2011 NAHMS feedlot and dairy heifer studies.

The USDA:APHIS National Animal Health Monitoring System collects data on health and health management in livestock and poultry populations throughout the USA in order to provide stakeholders with population estimates to use as benchmarks for comparison, to guide policy development, and to identify research needs and prioritize education efforts. Recent studies of both the beef cattle feedlot industry and dairy heifer rearing operations provided information about BRD occurrence as well as information about prevention and treatment practices used on these operations. While a great deal of effort is dedicated to BRD prevention, there are still opportunities to improve the strategies used. Despite efforts to prevent the disease, BRD continues to be widespread on both of these types of operations. [ABSTRACT FROM AUTHOR]
