Sinopsis

This book provides real guidelines on swine biosecurity methods, and it will be useful to veterinary surgeons, teachers and advisors as well as students who will provide for tomorrow’s industry. The format is deliberate to provide the farmer and advisor with an easy reference source with quick fixes; it is more of a “how to” than a text book. Many of the pages can be used by farmers as advice sheets which can be used around the farm to provide rapid and useful information on pathogen control.
