Lateralised Behavioural Responses in Livestock to Environmental Stressors: Implications for Using Infrared Thermography to Assess Welfare Conditions.

Abstract: Lateralised behavioural responses to environmental stressors have become more frequently used as indicators of social welfare in animals. These lateralised behavioural responses are under the control of asymmetrical brain functions as part of the primary functions of most vertebrates and assist in primary social and survival functions. Lateralised behavioural responses originating from the left hemisphere are responsible for processing familiar conditions, while the right hemisphere is responsible for responding to novel stimuli in the environment. The forced lateralisation and side preference tests have been used to determine the visual lateralised behavioural responses in livestock to environmental stressors. Limb preference during movement has also been used to determine motor lateralisation. Although behavioural investigations in livestock have recorded lateralised behavioural responses to environmental stressors, there are still limitations in the implication of lateralisation to other conditions, such as restraint and invasive procedures. Thus, it is important to have a non-invasive measure for these lateralised behavioural responses. Recently, lateralised behavioural responses have been correlated with the use of infrared temperature of external body surfaces, such as the eyes and coronary bands of limbs. This review summarised the different forms of the lateralised behavioural responses in livestock, especially cattle and horses, to environmental stressors, and the association between these responses and the relevant external body surfaces' infrared temperature, with the purpose of improving the use of non-invasive measures in assessing welfare conditions in animals. The combination of the lateralised behavioural responses and infrared temperature of external body surfaces to environmental stressors could improve the assessment strategies of welfare conditions and the related additional husbandry interventions that could be applied to improve the welfare of farm animals.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research article is about the analysis and implication of ‘lateralised behavioural responses’ in livestock, especially in cattle and horses, to determine their welfare conditions. The study explores various types of these responses and how they can be measured non-invasively by using infrared thermography of external body surfaces.

Understanding Lateralised Behavioural Responses

  • The term ‘lateralised behavioural responses’ refers to specific reactions displayed by an animal, which are controlled by either hemisphere of its brain. These responses are usually associated with the way animals perceive and respond to different environmental stimuli, hence serving as indicators of their welfare.
  • Usually, processes that are routine or familiar to the animals are managed by the left hemisphere. Conversely, unfamiliar conditions or novel stimuli responses are managed by the right hemisphere.
  • These responses are crucial for primary social and survival functions in most vertebrates, including livestock.

Assessing Lateralised Behavioural Responses

  • Researchers have developed tests, like the forced lateralisation and side preference tests, to measure visual reactions to environmental stressors in livestock.
  • To determine motor lateralisation, the researchers observe the animal’s limb preference during movement.
  • Despite the success in recording these responses to environmental factors, using them to assess other humane conditions, such as the animal’s state during restraint or invasive procedures, has shown limitations.

Infrared Thermography for Non-invasive Measurement

  • To circumvent the limitations of invasive measures, infrared thermography has been used recently. This tool can non-invasively calculate the external body surface’s temperature, such as eyes and the coronary bands of limbs. By comparing this data with known lateralised behavioural responses, a precise assessment of animal welfare is achievable.
  • The study states that exploring the link between these responses and the external body surface’s infrared temperature can improve using non-invasive measures to assess welfare conditions.

The Implication of the Study

  • The importance of this research lies in improving current strategies to assess welfare conditions in farm animals, which can lead to better farming practices and more humane treatment of animals.
  • The combined use of lateralised behavioural responses and infrared temperature readings could inform additional husbandry interventions to improve farm animal welfare.
