Iowa State University Extension Beef Specialist Beth Doran says energy needs change drastically in cold temperatures. “For every degree below 32 degrees, they need to increase their energy intake one percent,” said Doran. “Average daily gains are going to back off and feed efficiencies are going to be poorer than if we were dealing with more moderate weather.” Doran warns producers against changing rations to meet increased energy needs but says to simply increase the amount fed.
