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.

Breeding herd stability can be defined as a cessation of PRRS virus circulation in the breeding herd. This is an important milestone in a PRRS control program.
Based on this field experiment, we can conclude that Ingelvac PRRS MLV is safe to use in PRRS-positive boar.
All in all, a long term whole herd PRRS MLV vaccination approach is vital to reduce the losses in the farm due to PRRS infection.
The consequences of a PRRS infection for this farm go beyond the standard implications.
