One hundred years ago, researchers at what is now Colorado State University began investigating a disease affecting cattle on the state's high-mountain ranches. The disease, which caused significant death loss, p
When loads of stressed, high-risk calves arrive at the feedlot, it often makes economic sense to treat them all with antibiotics to prevent an almost-inevitable outbreak of bovine respiratory disease (BRD).
While the cattle industry continues to refine preventive measures, treatments and overall management, feedlot morbidity, mortality and costs associated with bovine respiratory disease (BRD) stubbornly refuse to improve.
n a recent feedlot trial conducted by Advanced Animal Diagnostics (AAD), the use of a new chute-side blood test (QScout® BLD) demonstrated that a feedyard in Nebraska could reduce antibiotic use 87% by selectively tr
While environmental factors and host genetics heavily influence BRD morbidity rates, understanding the genomic and molecular biology tools also can improve our understanding of pathogens and beneficial microorganisms .
