In the last decades, much research has been conducted on bovine viral diarrhoea (BVD), a disease which causes a variety of clinical signs as well as deaths, abortions and huge economic losses in the cattle industry worldwide. Despite the efforts to control BVD on farms, the virus has continued to spread and is still a concern for farmers and veterinary practitioners. This guide will provide readers with essential, practical and updated knowledge to understand and fight the disease regardless of the farm’s production system. This guide has been written by Francisco J. González Rodríguez, an experienced beef and dairy cattle consultant with a special interest in bovine viral diseases and cattle management.

Francisco J. González Rodríguez

He first obtained a bachelor degree in Biology and thereafter he graduated in Veterinary Medicine from the Complutense University of Madrid (UCM). He holds a Master’s degree in Business Administration by the Madrid Business School/Houston University (Repsol-Honda Award for Excellence in Marketing) and a Master’s degree in Virology by the UCM.

He currently works as an independent consultant in animal health and dairy and beef cattle management for several corporations in Spain, Italy and Portugal, and is responsible for marketing, training and technical activities such as epidemiological studies and clinical trials (supervision and execution). Formerly he worked for many years for the pharmaceutical industry as product manager in the livestock sector (including dairy and beef cattle) where he was involved in biological and medical products development, field research and training. He worked on the launch and follow-up of several drug products in both the pig and cattle industry. He has attended many courses in animal health, sales, marketing, negotiation, computing and leadership.
