A MULTIMODAL CLINICAL AND DIAGNOSTIC APPROACH TO BOVINE RESPIRATORY DISEASE COMPLEX (BRDC) IN DAIRY CALVES
Calf bronchopneumonia (BP), or Bovine Respiratory Disease Complex (BRDC), to date is still difficult to diagnose due to the multifactorial nature of its etiopathogenesis and aspecificity of clinical symptomatology. In this research project, four studies were conducted to investigate various aspects …

Lung auscultation as a predictor of lung lesions and bovine respiratory disease outcome in feed yard cattle
Bovine respiratory disease complex (BRDC) is the most common, and costly, disease in feed yard cattle. A review of the literature shows a correlation between the diagnosis of BRDC ante-mortem and respiratory lesions at slaughter. The objectives of the studies reported here were to: 1) validate a …

Evaluation of By-product Feedstuffs, Level of Concentrate, and Selenium and Vitamin E Injections on Performance and Health of Beef Calves in Backgrounding Systems
… system, which can lead to increased incidence of diseases, especially bovine respiratory disease complex (BRDC). Backgrounding cattle post-weaning and prior to feedlot entry may alleviate some of the more common stresses and typically diminished feed intake. Five trials were conducted with a total …
