Control and Elimination of Porcine Reproductive and Respiratory Syndrome Virus
Publish Date: April 13, 2012
Porcine reproductive and respiratory syndrome emerged as a new syndrome in the US swine population more than two decades ago (Keffaber, 1989). After its initial description, the disease was identified rather quickly in many countries throughout the world. In 1992 the virus was isolated in the US and also in 1992 the consensus decision at the International Symposium on Swine Infertility and Respiratory Syndrome (SIRS) held in St. Paul, MN was made to refer to the syndrome as Porcine Reproductive and Respiratory Syndrome (PRRS) and the virus as PRRS virus (PRRSv). PRRSv has been documented to mutate constantly by changing its genetic appearance (Murtaugh et al. 1995) which presents an important challenge for herd level and regional control.

Controlling Rats and Mice in Swine Facilities
Publish Date: April 4, 2012
Rats and mice can be a major economic threat around swine facilities. They consume and contaminate feed and cause feed losses through the gnawing of holes in feed sacks and wooden bins. They also have been implicated in maintaining or spreading diseases.

Control of Circovirus
Publish Date: January 3, 2012
Porcine circovirus type 2 (PCV2) is an ever-present virus within swine producing countries with most regions having evidence of infection. Minimizing exposure and controlling disease associated infection (Porcine Circovirus Associated Disease; PCVAD) can be accomplished through multiple or different strategies. There are six main (reported) approaches in the control of PCVAD: vaccination, minimizing simultaneous diseases that may aggregate PCVAD expression, management and nutritional changes, genetics, serotherapy, and depopulation and repopulation.
