Descriptive analysis of national bovine viral diarrhoea test data in England (2016-2020).

ABSTRACT:

Background

Bovine viral diarrhoea virus (BVDV) causes substantial economic losses to the cattle industry; however, control and eradication can be achieved by identifying and removing persistently infected cattle from the herd.
