What physiological response indicates cattle are under stress?

Increased heart rate is a well-documented physiological response indicating that cattle are under stress. When animals experience stress, their bodies release hormones such as adrenaline and cortisol, which prepare the body for a 'fight or flight' response. One of the immediate effects of this hormonal surge is an increase in heart rate, allowing for quicker blood flow to muscles and vital organs. This response is part of the animal's natural survival instinct, enabling it to react to threats more efficiently.

In the context of cattle showmanship, recognizing signs of stress, such as an elevated heart rate, is crucial for ensuring the well-being of the animals. Managing their environment, handling, and overall care can help minimize stress levels, leading to better performance in show situations. Understanding these physiological signals is beneficial for both caretakers and judges during shows, as stressed animals may not demonstrate their best behavior or physical condition.
