Effect of porcine circovirus type 2 vaccine on postweaning performance and carcass composition

PCV2 vaccination has a large impact on growth rate and on the proportion of pigs going to primary markets, but not on carcass fat depth, loin depth, or percent lean, measurements that are used to determine market value.

Abstract

Outcome of porcine circovirus type 1 (PCV1) infections in mid-gestational porcine foetuses

In the present study, virus replication and pathology were examined in porcine foetuses, inoculated with two PCV1 strains at 55 days of gestation.

Abstract

PRRSV enhances PCV2a and PCV2b replication and duration of shedding

The objectives of this study were to determine if co-infection of piglets with PRRSV and PCV2 has any affect on PCV2 shedding characteristics and if there are differences in shedding patterns between PCV2 subtypes (PCV2a and PCV2b) in co-infected pigs.

Oral fluids - Sampling

Over the last several years, new sampling, monitoring and diagnostic tools for the swine industry that are faster, simpler and more cost effective have been developed and validated. One of these techniques is the sampling and use of oral fluids (saliva) as specimens for diagnostics in swine.

Abstract

Establishment and maintenance of a PCV2-free breeding herd on a site after PCV2-associated reproductive disease

Elimination of infectious PCV2 from the breeding-herd site, the outcome after repopulation, and the attempt to derive PCV2-negative animals by offsite segregation are summarized.

Abstract

Impact of selected parameters on efficacy of pen based oral fluid collection from pigs

Oral fluid testing is becoming important tool in diagnostic and epidemiological studies of PRRSV, PCV2 and SIV infections. However, sample collection requires understanding of pigs behavior as many of it aspects directly impact the yield of oral fluid. The aim of the present study is to analyse factors affecting the amount of oral fluid collected in standard pig herds in Poland.

Abstract

Disinfection protocols reduce the amount of porcine circovirus type 2 in contaminated 1:61 scale model livestock transport vehicles

Objectives: To evaluate the effectiveness of disinfection protocols on porcine circovirus type 2 (PCV2) in 1:61 scale model livestock trailers and determine the infectivity of PCV2 DNA detected using a bioassay.

Boehringer Ingelheim satellite symposium highlights PCV2 landmarks

An important anniversary in the history of porcine circovirus type 2 (PCV2) has been marked at a special international pig veterinary satellite symposium held in Barcelona, Spain in June 2011 as part of the 6th International Symposium on Emerging and Re-emerging Pig Diseases. In 2011, this meeting heard, it is 15 years since the name PMWS was first proposed by Canadian investigators Ted Clark and John Harding for the novel wasting disease of growing pigs that they were observing in herds in Western Canada

Maternally derived antibodies at the time of porcine circovirus type 2 vaccination: does it matter?

One issue is to overcome maternal immunity, which is true for all PCV2 vaccines in the market, and another is whether the most from these vaccines is achieved independently of the PCV2 antibody titre at vaccination
