Guilty Guilt Guide

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.

Implementing a user-friendly format to analyze PRRSV next-generation sequencing results and associating breeding herd production performance with number of PRRSV strains and recombination events

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.

Effect of multiple vaccinations on transmission and degree of Mycoplasma hyopneumoniae infection in gilts

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.

The impact of discontinuing PRRS MLV vaccination in piglets in the single site in Thailand

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.

Performance improvement after using Ingelvac PRRS MLV against EU type infection

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.

PRRSV control in finisher pigs, a large scale barn study in a high dense area in USA

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.

Growth performance improvement and mortality reductions derived from a PRSS large-scale control project in the US

A 70000-sow multisite production system with breeding herds endemically infected with PRRSV1 and PRRSV2. 

Systematic breeding herd mass vaccination, followed by quarterly sow mass vaccination, and ongoing pig vaccination at weaning with Ingelvac PRRS MLV was applied.

A significant increase in ADWG and significant decrease in mortality was detected in both nursery and finisher pigs when compared against 24 months closeouts.
