Besides discussing the current local situation, the meetings were focused on
two major causes of reduced immunity in pigs: Postweaning Multisystemic Wasting
Syndrome (PMWS) and mycotoxins.
In total, more than 350 people attended these meetings.
The meetings were organised by Belgian feed
additives company Impextraco, which had invited Dr FranÃ§ois Madec, vice-director
of one of the Veterinary Research Laboratories of the French Agency for Food
Safety (AFSSA) and head of the Epidemiology Research Unit, who has a vast
experience of swine diseases in general and is one of a handful of experts on
PMWS in the world.
In two meetings in the Philippines, one in Manila and one in Cebu, Madec
talked about swine influenza and major viral diseases, like Classical Swine
Fever and PRRS and PMWS, having a severe impact on mortality in pigs.
He also explained how to establish a diagnosis and to prevent and control
Disease to be identified
Dr Romeo E Sanchez, associate
professor at the University of the Philippines Los BaÃ±os, described symptoms
recently observed on several commercial pig farms in Luzon, Philippines.
Indeed, since early 2007, many farms seem to have been affected by a similar
disease which results in severe outbreaks of high fever and abortions. Up to
now, the definitive identification of the causative agent of the outbreak has
not been accomplished, he noted. Evidence of infections with several pathogens,
both viral (PRRSV and SIV) and bacterial has been reported, however, the primary
cause still has to be identified.
Mathieu Cortyl (Impextraco Singapore) presented the economic impacts of
mycotoxins in swine farms, and focused on the interaction between mycotoxins and
The Asian tour also stopped in Thailand, with
meetings in Nakornratsrima province and in the Nakornpratom province. Here, Dr
Dachrit Nilubol from Chulalongkorn University (Bangkok) described a recent
outbreak that affected many farms in Thailand. At the time of the meeting, it
was estimated that 300,000 to 500,000 pigs died over the last months. The cause
seems to be a quite virulent form of TGE (Transmissible Gastro Enteritis).
Speaking at the meeting held in Nakornpratom province, Dr Prariwat Poonperm
from Kasetsart University (Bangkok) reviewed the PMWS situation in Thailand. He
had a practical approach to explain how it affects the farms, and also presented
some possible solutions.
