Heat Stress for Cattle Approaching? There’s an App for That


USDA’s Agricultural Research Service (ARS) has launched a new smartphone application that forecasts conditions triggering heat stress in cattle. The app is available at both Google Play and the App Store.

Compatible with Android and Apple mobile phone, the app issues forecasts one to seven days in advance of extreme heat conditions, along with recommended actions that can protect animals before and during a heat-stress event.

Cattle housed in confined feedlot pens are especially vulnerable to heat-stress events, notes Tami Brown-Brandl, an ARS agricultural engineer at the Roman L. Hruska U.S. Meat Animal Research Center (USMARC) in Clay Center, Nebraska.

In addition to high temperatures, weather-related factors like humidity, wind speed, and solar radiation can contribute to heat stress, adds Brown-Brandl.

Until the early 1990s, the National Weather Service issued livestock safety warnings that helped feedlot producers preempt losses or diminished productivity resulting from heat-stress events. Starting in the mid-2000s, USMARC researchers filled the void with a Web page, which is still available today, offering similar forecasts.

Recent increases in smartphone usage prompted ARS to design and launch a mobile-app that allows producers to access forecasts while they’re in the field.

The resulting “Heat Stress” app, which was beta-tested last year, is based on several years of field research conducted by Brown-Brandl, fellow ag engineer Roger Eigenberg and others at USMARC—including Randy Bradley. Bradley, an information technology specialist, is responsible for a color-coded heat-index map of the entire continental United States.

The app has been added to the Federal Mobile Apps Registry. See a list of ARS Mobile Apps.
