Research to delve into the mind of cattle

Posted by Nicole Eckersley on 9th December 2010

CSIRO is researching ways to improve the welfare of livestock by developing scientific methods for assessing how animals ‘feel’ in response to common management practices, with the aim of reducing stress and pain in livestock, and increasing wellbeing and productivity.

The research, partly funded by Meat and Livestock Australia, will use cognitive principles based on human psychological theories, to assess animal emotions.

“With increased public concern about the welfare of animals, and consumers seeking ‘animal welfare-friendly’ products, Australia’s livestock industries are focused on improving farming practices to meet changing expectations,” CSIRO scientist Dr Caroline Lee said.

“It is also internationally recognised that we must quantify not only the biological cost but also the emotional cost of animals used for production of food and fibre.

“This requires new methods to benchmark the welfare of animals in their on-farm environment.”

The science of objective measurement of animal welfare is relatively new. Current methods largely focus on quantifying biological indicators of stress – for example, via blood tests that show changes in animals’ physiology or immune systems.

“Australia’s livestock industries are focused on improving farming practices to meet changing expectations.”

Previous studies of animal behaviour have also been used to indicate obvious emotional states such as pain or discomfort, or preferences for different foods. However, all of these studies provide relatively limited information.

“Until now the major gap in our ability to assess animal welfare has been our capacity to understand the emotional states of animals in different farming situations, such as in intensive finishing systems or during droughts,” Dr Lee said.

“The challenge is to gain insights – in a scientifically rigorous way – into how animals’ minds work,” she said.

“This will take some time to work through and it is one of key areas of strategic science undertaken by CLI’s Livestock Welfare Team.

“Ultimately, the outcomes of this research will expand on our understanding of emotional and cognitive functions of livestock and the impacts of farming practices on animal welfare.”

The research will be based at CSIRO Livestock Industries’ research facility near Armidale, NSW, in collaboration with Dr Alain Boissy at the National Agronomy Research Institute in France.“It is also internationally recognised that we must quantify not only the biological cost but also the emotional cost of animals used for production of food and fibre.
