OSU's Mark Johnson Provides Tips for Managing Heat Stress in Cow-Calf Operations
This week, Mark Johnson, Extension Beef Cattle Breeding Specialist at Oklahoma State University offers his cattle breeding expertise. This is a part of the weekly series known as the "Cow-Calf Corner" published electronically by Paul Beck. Today, Johnson talks about heat stress.

Heat stress is caused by a combination of environmental factors including temperature, relative humidity, solar radiation, air movement and precipitation. During the summer we need to assess the heat stress that cattle are under. Cattle on pasture are not as susceptible to heat stress as feedlot cattle because they have the ability to seek shade, water and air movement to cool themselves. In addition, radiant heat from dirt or concrete surface is increased for feedlot cattle. At temperatures above 80 degrees Fahrenheit cattle can endure physiologic stress trying to deal with their heat load. Although cattle at this temperature are not at risk of dying they will have an increased maintenance requirement to cope with the heat.

Compared to other animals, cattle can't dissipate their heat load very effectively. Cattle do not sweat effectively and rely on respiration to cool themselves. A compounding factor on top of climatic conditions is the fermentation process within the rumen generates additional heat that cattle need to dissipate. Heat production from feed intake peaks 4 to 6 hours after feeding.

KC Sheperd visits with Dakota Moss of Livestock Risk Services. When the pandemic hit in 2020 the cattle markets along with the rest of the world suffered. Many farmers and ranchers altered their marketing plans on crops and livestock to try and prevent a loss in the down Covid markets. This led to cattle being held months longer than planned hoping for a better market. Unfortunately for many farmers and ranchers they had no choice but to sell much heavier cattle into a down market. Resulting in a lower $/cwt price and profits lost. Sheperd and Moss discuss some alternative options for producers with the Livestock Risk Protection program.
