Swine production in the Philippines (2/2)
Pig rearing practices in the country need a lot of improvement considering that about 70% of pigs are on a backyard level.

Risk and/or triggering factors of porcine circovirus
Between 1995 and 1997, at the beginning of an epizootic called “maladie de l’amagrissement du porcelet” (MAP), it was observed that the farms that were most affected and that had the most losses, generally presented obvious deviations from what we would consider to be a suitable management of the animals and facilities. This is why Dr. François Madec made a list of management practices with the aim of improving the anomalous situation observed.
An overview of North American PRRS eradication efforts
The use of diagnostics will allow producers and practitioners to work together towards the common goal of PRRS eradication
Swine influenza: epidemiology and emergence of new viruses
The first swine influenza viruses were all H1N1 and were for about 60 years in North America. In the middle 1980’s, there appeared in European pigs H3N2 viruses that were derived originally from humans and had adapted to pigs and were therefore known as human-like H3N2 viruses. These viruses have since appeared in other parts of the world most notably as H3N2 in the USA in 1998. These viruses however contained bits of human, avian and swine viruses and were therefore called triple re-assortants.
PRRS Eradication
Preventing vertical and horizontal spread of PRRSV from dam to offspring is critical for the production of naive replacement stock
PRRS Biosecurity
Trailers contaminated with PRRSV can serve as a source of infection for naïve pigs. Therefore, sanitation for livestock trailers and transport vehicles is considered a high priority when it comes to biosecurity practices.
PRRS control
The presence of subpopulations of exposed and non-exposed sows in chronically PRRSV-infected breeding herds assists in the maintenance of virus circulation in the breeding herd over time.
PRRS: Diagnostic testing methods
This article will focus on selected antigen and antibody detection methods based on their application by practicing veterinarians to field cases in the US.
PRRS: Transmission via indirect routes (2/2)
Migratory waterfowl have been proposed as vectors of PRRSV spread between farms, due to their migratory nature and their tendency to nest on or near to swine farm lagoons
Current sanitary problems in the United States
The focus of swine production in the USA has changed over the last five years. Many businesses in the sector have made radical changes in management both from the reproductive and the sanitary point of view.
Production factors associated with coughing and pneumonia in pigs
In the first of this series of articles on respiratory disease in pigs, the causes of coughing were reviewed. This second article reviews the production factors that are associated with respiratory disease.
Diseases in Europe (1 of 2)
Overall, the disease situation in Europe is very similar although there are some countries that have a problem with certain diseases that others do not have
PRRS: Transmission via direct and indirect routes (1/2)
In this second part the direct routes (infected pigs and contaminated semen) and indirect routes (fomites and transportation vehicles) of PRRSV are tackled, as is the persistence of the virus because the persistence of the infection is a characteristic of PRRSV infections in pigs and plays a major role in the control and eradication of the disease.
PRRS: Etiology and clinical manifestation
Scott Dee, the prestigious American veterinarian who is known worldwide for his research on the PRRS virus, will be in charge of this section which is dedicated exclusively to the PRRS disease. Every month a new article will be published related to subjects such as etiology and clinical signs, transmission routes, diagnostic testing methods, biosecurity or control and eradication.
