The Guilty Gilt Guide was written with a clear objective – to maximize the whole-herd performance of pig populations by helping gilts to reach their full reproductive potential and produce healthy pigs that reach their full genetic potential during grow-finish.
The open reading frames (ORF)5 represents approximately 4% of the porcine repro- ductive and respiratory syndrome virus (PRRSV)-2 genome (whole-PRRSV) and is often determined by the Sanger technique, which rarely detects >1 PRRSV strain if present in the sample.
Porcine reproductive and respiratory syndrome virus (PRRSV) is an important swine pathogen affecting the global swine industry.
Mycoplasma hyopneumoniae (M. hyopneumoniae) infections continue to result in significant respiratory challenges in the swine industry worldwide. Vaccination for M. hyopneumoniae is commonly utilized, as reduction in bacterial loads and clinical severity in vaccinated pigs have been shown. However, the effect of M. hyopneumoniae vaccination on transmission across different pig populations has been minimally investigated.

PRRSV can be transmitted through aerosols. It travel associated with particles and has been detected in air as far as 9.1 km from swine herds. Growing pigs represents the absolute majority of PRRSV infected pigs in an area. Growing pigs have a longer duration of viremia and shed PRRSV for a longer period than the adult breeding stock the control of PRRSV circulation in growing pig populations is essential. This can be achieved through a combination of correct biosecurity, pigflow, management and immunization.
These results confirmed the efficacy of Ingelvac® PRRS MLV in preventing HP-PRRS negative impact under Vietnam conditions in a sustainable manner
Despite dramatic improvements, the farm is still a case-control in progress, vaccinating with lngelvac PRRS MLV just barely 6 months as of data avallability
Based on the mortality change, stopping PRRS MLV vaccination resulted in big economic loss in this farm. The benefit-to-cost ratio between non-vaccinated and vaccinated is 7.03:1 based on the mortality alone
