There are a number of health challenges that are prevalent in pig production – and we know that biosecurity is the name of the game when it comes to disease prevention. Some diseases seem to evade even the strongest biosecurity plans and this can be frustrating for producers and their veterinarians as they try to achieve optimum care for their herds.
Porcine respiratory and reproductive syndrome is a disease that has circulated in the swine world for years – however a recent highly pathogenic strain of this virus is challenging pig herds. Dr. Doug MacDougald, a swine veterinarian working out of Southwest Ontario Veterinary Services has worked with producers in North America who have experienced outbreaks of this highly pathogenic PRRS strain – 144 Lineage 1C – and shares some case studies and practical tips for disease prevention.
