Free PEDv testing for pig producers

Bpex is funding free porcine epidemic diarrhoea virus (PEDv) testing for producers and vets to increase the chances of early detection.

If outbreaks of diarrhoea are encountered, pig-keepers or vets can send samples of faeces for testing to the Animal Health and Veterinary Laboratories Agency (AHVLA).  

Vets say that PEDv could spread quickly through the nation’s pig population if the industry is not vigilant. Bpex veterinarian Derek Armstrong said that evidence in the US shows it’s highly infectious. So infectious that “just one infected pig is all it would take to start an epidemic in this country, which could kill as much as 10% of the national herd”.

The National Pig Association (NPA) gave the following advice for what to look out for in pigs:

• The diarrhoea may be watery and piglets rapidly dehydrate. Piglets may be found dead before diarrhoea is noticed especially on outdoor units.

• High mortality in suckling pigs would be an early signal of virulent PEDv but the diarrhoea may resemble other causes of enteric disease in older pigs.

• Diarrhoea due to virulent PEDv in weaned and older pigs is transient and pigs recover, but intercurrent infections such as salmonellosis could mean that more prolonged diarrhoea or deaths are seen in growing pigs.

• A poor response to antimicrobial treatment would be expected in pre-weaned piglets.
