Abstract

Objective-To determine whether strict closure of a dairy herd and eradication of bovine viral diarrhea virus (BVDV) infection would decrease incidence of diarrhea in calves during the first 31 days after birth, whether specific risk factors were associated with incidence of diarrhea in calves, and whether diarrhea was associated with weight gain of the calves. Design-2-year cohort study. Animals-448 calves. Procedure-Calves were monitored from birth to 31 days of age. Fecal samples were tested for rotavirus, blood samples were tested for BVDV and antibodies to BVDV, and serum samples were tested for IgG concentration; Risk factors were evaluated by means of survival analysis. Results-incidence of diarrhea in calves decreased significantly after strict closure of the herd and eradication of BVDV infection. Risk factors for diarrhea in calves interacted in a multifactorial way. Rotavirus infection and low serum IgG concentration increased the risk that carves would develop diarrhea. Carves that developed diarrhea gained significantly less weightthan calves that did not develop diarrhea. Clinical Implications-To control diarrhea among carves in a dairy herd, emphasis should be on maintaining a strictly closed herd free from BVDV infection. However, other measures, such as measures to prevent rotavirus infection and to ensure that calves. receive an appropriate amount of colostrum after birth, should also be-taken.
