As part of its mission to fund research with direct application to the profession, the American Association of Swine Veterinarians Foundation awarded $100,000 in funding for research. Ross Kiehne, chair of the AASV Foundation, announced the selection of four research proposals for funding during the Foundation's luncheon on Feb. 27 held during the AASV Annual Meeting in Indianapolis. The foundation granted funds to support efforts by principal researchers, all from Iowa State University.

The Foundation granted $30,000 to Marcelo Almeida and co-investigators to fund the proposal, "Comparison of the pathological and clinical effects of an F18 enterotoxigenic Escherichia coli containing a tia adhesin gene against a contemporary F18 Escherichia coli strain." The two objectives of the study are to compare the clinical impact and to assess the efficacy of a commercially available F18 E coli competitive exclusion product in controlling postweaning diarrhea caused by an ETEC-F18+/tia+.

Jianqiang Zhang and co-investigators received $30,000 to fund the proposal "Evaluation of the protective efficacy of three PRRSV MLV vaccines against the newly emergent PRRSV 1-4-4-L1C variant strain in weaned pigs." The objective of this study is to evaluate the protective efficacy of three porcine reproductive and respiratory syndrome modified live virus vaccines against the newly emergent PRRSV 1-4-4 L1C variant strain in a weaned pig model.

Daniel Linhares and co-investigators were awarded $21,736 to fund the project, "Assessment of population-based sampling for detection of influenza A virus RNA in breeding herds." The two objectives of this project are to compare the probability of detection of influenza A virus-swine RNA between individual and population-based samples and to establish the probability of identifying IAV-S positive litters by using different sample sizes.

The Foundation granted $18,264 to Gustavo Silva and co-investigators to partially fund the project, "Comparing herd-level sensitivity to detect PRRSV outbreaks among different surveillance methods." The overarching goal of this study is to assess herd-level sensitivity among different surveillance samples to detect PRRSV outbreaks. A secondary objective is to characterize the impact of PRRSV.

Investigators will share results at various swine meetings and in peer-reviewed publications.

Teddi Wolff chaired the scientific subcommittee responsible for reviewing and scoring the 11 proposals received for consideration, and she joins the Foundation in thanking Monte Fuhrman, Amber Stricker, Todd Wolff, Eva Jablonski and Brett O'Brien for their participation on this important subcommittee.

An overview of past and current projects funded by the AASV Foundation is available here. The foundation will issue its next call for research proposals in Fall 2022.
