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.

Mycoplasma hyopneumoniae (M.hyo) is the primary pathogen of enzootic pneumonia, a chronic respiratory disease in pigs. Infections with M. hyo are highly prevalent in almost all swine producing areas, and they cause significant economic losses due to increased medication use and decreased performance of the pigs. Moreover, M. hyo is also considered to be one of the primary agents involved in the porcine respiratory disease complex (PRDC).
After outbreaks of porcine reproductive and respiratory syndrome virus (PRRSV) infections in sow herds, the time to stability of the sow herd can take 18 to 55 weeks.1,2 Different sampling strategies (e.g., processing fluids, serum, or oral fluids) have been described to assess the PRRSV-status after implementing control measures like sow vaccination, improvement of hygiene protocols, lowering stocking density, and piglet flow optimization.1,3 Thus, we aimed to compare the different described strategies regarding their applicability for monitoring the PRRSV-status in a 3000-sow herd after a PRRS outbreak.
The aim of the present study was testing of the efficacy of Ingelvac PRRSFLEX EU in decreasing viremia levels and viral shedding in piglets after a challenge with a virulent PRRSV-1- isolate (PRRSV AUT15-33) causing severe clinical problems in the field.
Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the leading swine pathogens1. It is well known that the air temperature and its humidity are crucial to the PRRSV survival. Some studies have identified a correlation between a new PRRSV infection and the season in type 2 environment2,3. The intensive PCR diagnosis effort done by Boehringer-ingelheim animal health Spain, to reveal PRRS herd’s status since 2015, has generated a huge database to work with. The sequencing of these positive samples is provided whenever the veterinarians report clinical signs or changes in the PRRS status.
