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.

PRRS is circulating in about 85% of the Dutch finishing pigs resulting in an estimated loss of 60 grams in ADG during the finishing pig period (1). In a 600 sow head farrow to finish farm with a historical growth of 783 grams/day, Circo-vaccination was implemented. A group of pigs was also vaccinated against PRRS to evaluate its effect on ADG.
PRRS type 1 infections can play a role in finishing pig performance. However, with many pathogens involved in for instance airway infections it is hard to prove which infection is the limiting factor in optimal pig production. The objective of this study is to evaluate the effect of the PRRS type 1 vaccine Ingelvac PRRSFLEX EU®.
Infection with porcine reproductive and respiratory syndrome virus (PRRSV) may lead to significant losses in productivity of breeding and growing pig herds1,2. Performance data was monitored over two years in a commercial farm in Croatia, which faced an acute PRRS outbreak and subsequently implemented changes in the vaccination program. The present abstract presents the results of nursery mortality. Sow performance is presented in a second abstract.
