Abstract

The relationship between bovine corona virus (BCV) titres and disease occurrence, and weight gain, in feedlot calves was investigated. 202 calves were enrolled in the study and followed for the first 28 days on feed. Outcome variables examined were risk of treatment for bovine respiratory disease (BRD) and total weight gain. Titres at day zero and change in titre to BCV and bovine viral diarrhoea virus (BVDV) were measured to examine this effect.
