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.

A PRRSV-positive farrow to finish farm with 1700 sows in the western area of Thailand.
The effect of stopping PRRS MLV vaccination in the nursery unit was evaluated.
Based on the mortality change, stopping MLV vaccination resulted in big economic loss in the farm.
Two-site production farm with 500 sows located in South Korea.
The efficacy of Ingelvac PRRS MLV administered in 7-week-old piglets was assessed in a grow-finish farm infected with PRRSV1 and secondary bacteria.
The group of pigs vaccinated with Ingelvac PRRS MLV showed better performance and less clinical signs.
Nursery pig sites utilizing and all-out flow from a large commercial production system located in North Carolina, USA.
A strategic use of Ingelvac PRRS MLV was applied in nursery pigs and the outcome compared to the one from contemporary non-vaccinated control pigs.
Ingelvac PRRS MLV demonstrated significant benefit in improved weight gain per day and livability %, and significant reduction in mortality % in finisher pigs.
