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 cause significant impact on reproductive performance in endemically infected herds. This study aimed to investigate sow performance before and after implementation of a sow herd vaccination against PRRSV on a farm in Serbia.
Porcine Reproductive and Respiratory Syndrome (PRRS) Virus is one of the major pathogens in pigs that have a significant economic impact on the swine industry worldwide. Modified life vaccine (MLV) against PRRSV has been demonstrated as an effective tool to control clinical signs related to infection. In literature, it is described that maternally derived antibodies (MDA) might interfere with MLV vaccination efficacy.
Ingelvac PRRS MLV was shown to reduce European PRRSV field strains from infected populations significantly. In distinct herds with well control health management and production systems, PRRSV could be eliminated from piglets produced from sows vaccinated
Due to the immediate vaccination programme following the PRRSV outbreak, an immediate and stable immunity withinthe whole herd was established by which the PRRS fieldvirus was successfully eliminated from the herd.
