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.

CUSUM charts are useful tools to detect cumulative deviations from the target; this SPC monitoring showed a potential benefit minimizing the severity and duration of PRRSv outbreaks in farms B and C using MLV vaccine as a contingency vaccine.
The economic benefit of 3FLEX in comparison to the identical but separately administered vaccines can at least partly be assigned to the reduction of stress caused by multiple handling and injections
The modified-live PRRSv vaccination program resulted in sustained, acceptable PRRS control in the breeding herd and post-weaning pig production
The results of this study show the efficacy of mass herd vaccination to stabilize the sow herd and to production of naïve weaned pigs, allowing a better assessment of control tools of PRRSV in growing pigs.
