The pain scale: 6 behavioral signs that a cow is in pain

Do you know how to recognize a cow in pain?

Research from Scandinavian scientists shows that cows in pain show specific behavioral symptoms.
(Read the full article here)
They summarized this in a pain scale for dairy cows, which was then tested by comparing the results from behavioral exams to the results from clinical exams.

On the pain scale, six factors are important for scoring pain levels:

  1. Attention towards the surroundings
  2. Head position
  3. Ears position
  4. Facial expressions
  5. Response to approach
  6. Back position

In our CowSignals® training, we teach people to check at least three factors: the cows’ attention towards the surroundings, head position, and back position. These are very clear indicators. But some behavioral clues can be hard to spot. When observing your herd, you may not have time to check each individual cow for subtle clues like ear position and facial expression.

Luckily, you don’t have to be an expert in reading cow facial expressions to observe their health. Very often, the causes of the pain are much easier to detect the behavioral symptoms. If you spot a cow with wounds, contusions, damaged teat ends, or lameness symptoms, you can safely bet that she is in pain without checking every behavioral clue.
And recognizing pain is only the beginning (or the end, depending on how you look at it). A cow in pain very often means a health problem that could have been prevented. Many mastitis cases can be prevented by changing the milking routine, and many wounds would not have appeared in a barn with larger cubicles.
That is why we need to train as many people in the dairy industry as possible to look at both cows and barns in a structured way, to recognize the signals that will lead to health problems and to start preventing pain instead of curing it.

Still, this pain scale is a nice, detailed tool to keep in mind while assessing a herd. So next time you see a cow with a tense facial expression, remember to ask yourself the ‘why-question’ to find out what causes it, and start thinking about solutions.

Such pain scales can be a useful tool in order to evaluate large differences. I do object when presented as an objective scientific method. All studies rely on correlations between overt behaviours and physiological states that we humans deem to be more or less severe. Although common sense tells differences must exist, an important subjective factor remains. Even in humans, who can communicate feelings verbally, a more precise evaluation is difficult. Pain stimuli are not limited to thalamic structures but are treated by frontal cortical mechanisms. Personality plays a role. Sturdy people can complain less than "touch-me-not" ones besides actual physiological hyperalgesia.

Thanks for sharing your thougts, Frank. Valid point. Luckily, the authors recognize this as well; in paragraph 4 of the paper, they present a more nuanced view on the possible applications and the limitations of the method.
