Prevalence of porcine reproductive and respiratory syndrome virus and porcine circovirus type 2 in piglets after weaning on a commercial pig farm in Japan

To investigate the transition in concentration of porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) and antibody for these viruses in serum, serum samples were collected from 29 pigs on weaning day and at 7, 14, 21, 28, 53, 84, and 120 days after weaning.

March 2010: The latest in new technology!

Use of saliva for haptoglobin and C-reactive protein quantifications in porcine respiratory and reproductive syndrome affected pigs in field conditions

The purpose of this study was to study the use of saliva samples as alternative to serum for acute phase protein (APP) quantifications in pigs at field conditions.

A stochastic mathematical model of the within-herd transmission dynamics of porcine reproductive and respiratory syndrome virus (PRRSV): Fade-out and persistence

A stochastic, mathematical model of a farrow-finish pig herd was developed and used to investigate the within-herd transmission dynamics of PRRSV, and to examine patterns of on-farm persistence and fade-out.

Philippines: hog production inched up 1.2% in 2009

Philippine hog production rose by a mere 1.2% in 2009, but this is still better than the 1.6% contraction it suffered in 2008.

Age-dependent resistance to Porcine reproductive and respiratory syndrome virus replication in swine

Since the porcine adaptive immune system is not fully competent at birth, we hypothesized that age influences the dynamics of PRRSV infection.

New viral threat to UK pig industry

A new disease which poses as great a risk as foot-and-mouth disease could devastate the British pig industry unless controls are tightened up.

Diagnosis of Porcine Respiratory and Reproductive Syndrome

In reproductive disease, submission of several whole affected litters is advisable to provide material for diagnosis of PRRSV and other diseases causing reproductive or neonatal problems.

Abortion

Abortions are not always witnessed in yards or extensive systems. Evidence is provided by sudden weight loss and a vulval discharge.

China - New PRRS outbreak

China's Ministry of Agriculture has announced that an outbreak of PPRS has reemerged in five provinces of China this year.

IDEXX Laboratories Announces New Porcine Reproductive and Respiratory Syndrome Test Kit

Genetic resistance to disease – An Introduction

The performance and conformation of the pig (the phenotype) depend on the combined effects of its genetic make-up (the genotype), which is mostly fixed at conception, and the environment, which includes health, nutrition, management, housing and climate.

USA - Industry groups meet to explore PRRS eradication

Producer and veterinary members of a pork industry task force conferred at the Leman Swine Conference last week in St. Paul, MN, to explore setting a course for possible eradication of porcine reproductive and respiratory syndrome (PRRS).

PRRS Eradication: A dream or missed opportunity?

Since 1987, Porcine Reproductive and Respiratory Syndrome virus (PRRS) has become a global drain on pig productivity, profitability, and many a producers’ morale. One thing that remains certain is PRRS virus continually finds ways to circumvent our best bio-management efforts. PRRS marches on in a ceaseless continuum of antigenic change making current vaccines and other control techniques of limited value.

New PRRSV strain undetected by routine PCR

Recently a PRRSV boar stud infection went undetected through the routine PCR monitoring protocol. Results from the investigation suggest that a new PRRSV strain has emerged.

Vietnam - PRRS outbreak

An outbreak of blue ear disease (PRRS) was reported this week in Vietnam’s southern province of Bac Lie in the Mekong Delta.
