Monitor outcomes to ensure long-term PRRS control success. Track diagnostic results and pig performance data across sow, grow-finish, and whole production systems to detect low-level virus circulation, guide decisions, and move herds toward stable or negative status.
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.
The consequences of a PRRS infection for this farm go beyond the standard implications.
In conclusion, this summary confirms the ability of a modified live PRRS vaccine (Ingelvac® PRRS MLV) to provide heterologous protection following virulent challenge with the European LV strain of PRRS.
The use of Ingelvac PRRS® vaccines can significantly reduce lung lesions following challenge with heterologous isolates (86-94% ORF5 nucleotide similarity) in the three-week-old pig respiratory challenge model. However, the efficacy of Ingelvac PRRS® MLV vaccine against current virulent PRRSV isolates, such as RFLP 1-7-4, has not been reported to date.
