A critical review of fear tests used on cattle, pigs, sheep, poultry and horses.

Abstract: Fear is arguably the most commonly investigated emotion in domestic animals. In the current review we attempt to establish the level of repeatability and validity found for fear tests used on cattle, pigs, sheep and goats, poultry and horses. We focus the review on the three most common types of fear tests: the arena test (open field), the novel object test, and the restraint test. For some tests, e.g. tonic immobility in poultry, there is a good and broad literature on factors that affect the outcome of the test, the validity of the test and its age dependency. However, there are comparatively few of these well defined and validated tests and what is especially missing for most tests is information on the robustness, i.e., what aspects can be changed without affecting the validity of the tests. The relative absence of standardized tests hampers the development of applied ethology as a science.

This research is a review of the effectiveness and repeatability of fear tests used on domestic farm animals such as cattle, pigs, sheep, poultry, and horses, focusing on three main types of tests: the arena test, the novelty object test, and the restraint test.

Introduction

  • The research article is a review of various fear tests used on a variety of domestic animals, including cattle, pigs, sheep, goats, poultry, and horses.
  • The aim of this review is to examine the level of repeatability and validity of these tests, focusing on the three most commonly employed tests: the arena (open field) test, the novel object test, and the restraint test.

Types of Fear Tests

  • The arena (open field) test involves observing the animal’s behaviour in an open space.
  • The novel object test introduces an unknown item to the animal to observe the reaction.
  • The restraint test involves restricting the animal’s movement and observing its response.

Evaluation of the Tests

  • The review indicates that certain tests, such as tonic immobility (a state of temporary paralysis) in poultry, have a broad and substantial body of literature discussing the factors that influence the outcome, validity, and age dependency of the test.
  • However, the researchers noted that these comprehensive and validated tests are not the norm, and there is insufficient data on most other fear tests.

Need for Robustness and Standardization

  • The article underlines the urgent need for an investigation into the robustness of these fear tests. Specifically, the researchers seek to understand which aspects of the tests could be modified without affecting their validity.
  • The lack of standardized tests negatively impacts the development of applied ethology, the scientific discipline that studies animal behaviour in the natural environment, according to the authors.
