ILL-THRIFT IN WEANERS

A pig unit in Ireland expanded to 1000 sows within a year. Piglets are vaccinated against PCV-2 and EP. The breeding herd is vaccinated against PRRSv with a MLV. Weaner pigs are overstocked. There is an increase of weaners losing their body condition and abdominal panting. Wean to finish mortality ranges from 10 to 15%.

PRESENCE OF ROTAVIRURUS TYPE C IN NEONATAL DIARRHEA. PRELIMINARY RESULTS

Rotavirus is a major cause of diarrhea in piglets. Rotavirus type A is the most prevalent, but other rotavirus types have been described. Rotavirus type C is the second in prevalence but its implication in digestive process could be underestimated. The objective of this study was evaluating the presence of Rotavirus type C in neonatal diarrhea on commercial pig farms in Spain.

Congenital tremor Type A-II in newborn piglets is caused by transplacental transmission of a novel pestivirus

Congenital tremor is a well-known phenomenon in newborn piglets. It is characterized by tremors of the head and limbs that vary in severity, but are reducing or even absent during sleep. They last for several weeks to months but decrease in severity as the pigs grow older. Historically, congenital tremor has been classified as type A, with defined pathological characteristics and partially known etiology, or type B, with unknown etiology.

Could avian H9N2 influenza viruses become a threat to swine? Lessons from experimental studies in the pig.

It is a classical but unproven hypothesis that pigs can serve as intermediate hosts between birds and humans in the generation of novel pandemic influenza viruses. Yet the single pandemic virus of likely swine origin is the 2009 pandemic H1N1 virus (2009 pdm), a virus with genetic components of swine, human and avian origin (reassortant).

PRRSv INFECTION BY SEMEN IN A PIG UNIT IN NORTHERN IRELAND

PRRSv is enlisted as a Notifiable Disease in Northern Ireland (The Diseases of
Animals –Northern Ireland- Order 1981) after it was first diagnosed in 1997. The
prevalence of infection in 2011 was 36.6% of the Northern Irish pig producers.
In April 2013, the main boar stud of the island, located in the Republic of Ireland, was
diagnosed with PRRSv infection. This stud was supplying semen to around 70% of
producers in the whole island.
