New HotHog app predicts heat stress in pigs

HotHog, a new smartphone application that predicts heat stress in pigs, is now available for download and use, a team of Agricultural Research Service (ARS) and university scientists announced this week.

Available in the Apple App Store and Google Play Store, HotHog taps into local weather data to predict the relative comfort or heat stress levels of pigs on an hourly, daily or weekly basis. Swine producers can then use this information to take pre-emptive measures, like ensuring plenty of drinking water, cooling the pigs with fans or mists, and limiting transport to early morning hours.

Video: Season 6, Episode 6: The Science Behind Sudden Sow Deaths

Recent necropsies have revealed new insights into unexplained sow deaths, helping producers better understand the causes behind these losses. A recent study led by Laura Solis, a graduate student at Iowa State University, examined why these deaths occur, many around farrowing. In some cases, animals were sent to the lab for further analysis, as discussed by Dr. Marcelo Almeida, assistant professor in the College of Veterinary Medicine at Iowa State University. The episode also features Dr. Chris Rademacher, clinical professor and swine extension veterinarian as well as associate director of the Iowa Pork Industry Center, who asks questions of what seasonal factors there were and management strategies that can influence herd health outcomes.
