Natural Behaviour Is Not Enough: Farm Animal Welfare Needs Modern Answers to Tinbergen's Four Questions

Area of Science:

• Animal Welfare Science
• Ethology
• Agricultural Science

Background:

• The food industry frequently equates 'natural behaviour' with good animal welfare.
• This assumption stems from an outdated understanding of animal behavior and frustration.

Purpose of the Study:

• To critically evaluate the link between natural behavior and animal welfare.
• To demonstrate why reliance on 'natural behaviour' alone may not guarantee improved welfare in commercial farming.

Main Methods:

• Utilized Niko Tinbergen's Four Questions framework to analyze the natural behavior-welfare relationship.
• Reviewed established methods for assessing animal preferences, such as choice tests and operant conditioning.

Main Results:

• The study highlights that 'natural behaviour' is not a sufficient indicator of welfare without evidence of its importance to the animals.
• Methods exist to determine what animals intrinsically value, which is a more direct measure of welfare.

Conclusions:

• There is no inherent, necessary link between performing natural behaviors and an animal's welfare.
• Assessing what animals value, through methods like choice tests, is essential for improving welfare in commercial agriculture.
• Collaborative research is needed to implement welfare strategies based on animal values in practical farming systems.
