Detection of Porcine Endogenous Retrovirus (PERV) viremia in diseased versus healthy US pigs by qualitative and quantitative real-time RT-PCR

20-Apr-2011
Previous studies have linked levels of porcine endogenous retroviruses (PERV) with poor health and disease in pigs. To determine the levels of expression of PERVs and their potential association with disease expression, real-time reverse transcriptase (RT) PCR assays were used to assess PERV-ABC, PERV-C and PERV-A/C levels in three commercial swine operations in the United States.

Effects of transport conditions and vehicle design on the welfare and meat quality of pigs in western and eastern Canada

15-Apr-2011
The objective of this study was to examine the influence of transport conditions on the behaviour, physiology and welfare of pigs in eastern and western Canada, in both summer and winter. Our goals were to evaluate differences between truck types, truck compartments and seasons in each region, and to use this information to identify problem areas and potential solutions.

Elimination of Porcine Respiratory Coronavirus

08-Apr-2011
A research protocol was designed to eradicate the virus in pigs sourced from a PRCV positive sow herd. The sow herd is a 150 farrow to finish herd, under one roof, and is PRRS and Mycoplasma hyopneumoniae negative. Forty piglets were weaned from nursing gilts/sows at 5 days of age and removed to a separate nursery which had been thoroughly disinfected and cleaned.

Longitudinal study of swine influenza virus infection in a farrow to finish farm

16-Mar-2011
With the objective of determining the dynamic of influenza virus (SIV) infection in a closed cycle farm, investigators from CReSA (Spain) selected a complete batch of piglets weaned at 3 weeks (n=121) from a farm of sows that tested positive for SIV antibodies. They took nasal swabs and blood samples weekly, from week 3 to week 13, and then at weeks 15, 17, 20 and 24. On each visit to the farm, a clinical inspection of the sows was carried out.

Effect of Ascaris suum infection on performance of fattening pigs

09-Mar-2011
Scientific investigations of production losses in pigs due to roundworms are rarely conducted in commercial farms, despite the fact that this information is needed to decide whether anthelmintic treatment is cost-effective or not. Therefore, the aim of our study was to compare performance in fattening pigs treated or not treated for Ascaris suum infections.
