Influenza A virus in swine (IAV-S) is costly to the swine industry, especially when coinfection with other respiratory pathogens is present. The implications of these coinfections are reflected in both higher mortality rates and reduction in ADG.
Historically, uncomplicated IAV-S has been shown to lead to an estimated loss of more than $3 per pig; when present with concurrent infections, the loss associated with IAV-S can be greater than $10 per pig.1
Recent data suggest that coinfection can lead to even greater economic loss:
When IAV-S and porcine reproductive and respiratory syndrome (PRRS) simultaneously infect pigs in late nursery, losses can average $18 per pig.2
Until recently, there have been few tools commercially available to provide protection against influenza and its impact on the health and performance of growing pigs.
Production and performance with Ingelvac Provenza™
Ingelvac Provenza™ is a live attenuated influenza vaccine (LAIV) that can be given to pigs as early as day one via intranasal administration. It has recently been evaluated in 2 commercial 5000-sow flows.
Case study #1: ADG, feed conversion ratio (FCR), average market weight, and days to market3
Objective: To assess measures of growing pig performance in a 2-sow farm flow (5000 total sows) from a large commercial swine operation in the midwestern United States before and after the introduction of Ingelvac Provenza™.
Investigators: J. Morgan, K. Kovach, C. Goodell, K.M. Cicconi-Hogan
Method: Observe measurable differences in key performance indicators (KPIs) (ADG, FCR, average market weight, and days to market) after vaccination with Ingelvac Provenza™.
Key takeaway: Pigs vaccinated with Ingelvac Provenza™ went to market nearly 7 days sooner, with an increase in average market weight of over 3 lb.
Case study 2: ADG and mortality4
Objective: To assess the performance of growing pigs in an IAV-endemic commercial 5000-sow farm flow before and after the implementation of Ingelvac Provenza™.
Investigators: E. Mondaca-Fernandez, E. Lowe, C. Goodell, K.M. Cicconi-Hogan
Method: Use summary nursery and finishing closeout data to compare ADG and mortality, prior to and after vaccination with Ingelvac Provenza™.
Significant improvements of 0.10 lb/day wean to finish ADG and mortality reduction of 0.95% were observed after the initiation of Ingelvac Provenza™ in a flow previously diagnosed as endemic for IAV-S.
Building a strong immune foundation throughout the herd
These studies have shown that vaccination with Ingelvac ProvenzaTM can be a valuable tool in current IAV-S protocols and positive vaccine impact can be measured by standard performance targets.
