Heat Stress And Reproduction In Beef Cattle, Reganne K. Briggs, Kerry A. Rood

All Current Publications

Reproduction could be considered the most important production trait on a cow-calf operation. Economic outputs are sustained when cattle rebreed and calve every year in a timely manner. However, when cattle are unable to rebreed efficiently, profits may decrease for producers. It is well known that heat stress can negatively impact reproduction in cattle (Jordan, 2003). The Intermountain West has been impacted by drought and increasing temperatures, both of which can impact reproduction rates in cattle. This fact sheet helps producers understand the consequences of heat stress on cattle reproduction and how they can manage reproduction during increasing temperatures.
