Could flies and gnats pose more harm to your swine herd than just a nuisance? A new study says the answer is a resounding yes. A first-of-its-kind report from the Walcott Veterinary Clinic in Walcott, Iowa, shows that house flies and gnats transmit rotavirus and sapovirus in swine nurseries.
Allison Knox, the lead researcher on the study, chose a sow farm and nursery in southeast Iowa with histories of both rotaviral and sapoviral challenges. A pilot study was conducted in 2021 and an expanded study was completed in 2022. Through a series of rectal tests and environmental samples tested at the Iowa State Veterinary Diagnostic Lab, proof of concept was pulled from the data.
