Recognizing Heat Stress
Pictured below are cattle displaying increasing levels of heat stress. A description of typical behaviors is associated with each level. Vulnerable animals will show stress symptoms early. Varying stages of stress will be evident throughout the herd as environmental conditions become more intense. As more animals display signs of increasing heat stress, action should be taken.
