Here, we describe the PRRS epidemic in Chile between October 2013 and April 2015, and we studied the origins and spread of PRRSV throughout the country.
Porcine Epidemic Diarrhea Virus (PEDV), Porcine Delta Corona Virus (PDCoV), and Transmissible Gastroenteritis Virus (TGEV) are major threats to swine health and contaminated feed plays a role in virus transmission.
Weaning stress accompanied by outburst of aggression is a critical point in pig production as it compromises piglets’ welfare and leads to poor growth rate and health problems. Therefore, a weaning methods to smoothen the lactation–weaning transition are of great importance.
Guided interventions as a team effort of farmer and herd veterinarian/other advisors have shown to be a promising method in the reduction of antimicrobial usage in pig production.
Influenza A viruses (IAVs) are endemic in swine and represent a public health risk. However, there is limited information on the genetic diversity of swine IAVs within farrow-to-wean farms, which is where most pigs are born.
The researchers developed a single-tube, rapid rtPCR that is capable of detecting 10 copies of PRV glycoprotein B ( gB) DNA per 20-µL total volume reaction.
According to the results, the optimal density was 1.2 m2/pig considering welfare and building utilization.
