ABSTRACT
Activation of the innate immune system and acute phase response (APR) results in several responses that include fever, metabolic adaptations and changes in behavior. The APR can be modulated by many factors, with stress being the most common. An elevation of stress hormones for a short duration of time can be beneficial. However, elevation of stress hormones repeatedly or for an extended duration of time can be detrimental to the overall health and well-being of animals. The stress and APR responses can also be modulated by naturally-occurring variations, such as breed, gender, and temperament. These three natural variations modulate both of these responses, and can therefore modulate the ability of an animal to recover from a stressor or infection. Understanding that cattle have different immunological responses, based on naturally occurring variations such as these, may be the foundation of new studies on how to effectively manage cattle so that health is optimized and production is benefited.
