Oral fluids are practical, fast, easy, cost-effective and reliable methods for sampling pig populations, but it has not been easy or practical to obtain such samples from suckling piglets...
Although the use of vaccination was effective in stabilizing the sows, the results of these case studies emphasized that elimination of PRRSV from the nursery can only be accomplished if vaccination and partial depopulation/ disinfection are supported by strict implementation of all recommended management procedures, including AI/AO.
The purpose of this study was to compare efficacy of LCE (load-close-expose) using attenuated PRRSV to that using live-virus exposure on breeding herds acutely infected with PRRSv.
The economic potential lost in a unit positive to PRRS could be around 35 – 37% of net unit margin.
Needle-free injection technology improves the dispersion of vaccines throughout the tissue.
NFID administered swine vaccines can use half to a tenth of the dose required for intramuscular vaccines because of the higher antigen dispersion and contact with the antigen presenting cells found in skin.
A method to quantify the relative economic importance of pig health status at placement by specific pathogens (PRRSv and PEDv) and to estimate the effect of a specific type of PRRSv at a specific production system is presented.
