How Cattle Perceive Their Surroundings – New Review Study from SLU

The review shows why the way cattle see, hear, smell, taste and feel should influence how we design barns, handling systems, and animal environments.

"Cattle experience their surroundings through a rich combination of sensory input, previous experiences, and emotions. What may seem insignificant to us can be highly meaningful to them," says Maria Vilain Rørvang, Associate Professor and lead author of the study.

The central conclusion of the study is that cattle do not simply react to external stimuli. Rather, they actively interpret their environment by integrating sensory information with previous experiences and emotional states.

The article, The sensory world of cattle: abilities, limitations, and perceptual challenges in human-designed environments, published in Applied Animal Behaviour Science, highlights findings including:

• Vision differs from that of humans. Cattle have a wide panoramic field of vision that helps them detect predators, but their depth perception is limited, and they adapt slowly to rapid changes in lighting conditions. Shadows, reflections, and sharp contrasts can therefore cause uncertainty or fear.
• Hearing extends to frequencies beyond the human range. At the same time, cattle are less precise at locating the source of sounds, meaning that sudden noises outside, and even within, their field of vision may be particularly difficult for them to interpret.
• The sense of smell is likely more important than previously assumed. Odours are used for individual recognition, play a key role in the bond between cow and calf, and may also convey information about the emotional state of other animals.
• Touch has both physical and social significance. Gentle tactile contact, social grooming and the use of mechanical cow brushes appear to provide positive experiences that strengthen social relationships and promote good animal welfare.
• Taste is closely linked to learning. Cattle develop food preferences through experience and continuously adjust their choices based on the consequences of what they have previously eaten.

"Perhaps the most important insight is that cattle do not rely on one sense at a time. They combine vision, hearing, smell, taste and touch into an integrated perception of the world, with different senses becoming more or less salient depending on the situation. In some cases, smell may be the most important source of information; in others, hearing," says Maria Vilain Rørvang.

Based on these findings, the researchers present a conceptual framework describing how animals' combined sensory experiences shape their interactions with their environment. The framework can be used to analyse how housing environments, handling routines, and production practices are perceived from the animals' perspective.

"We conclude that designing production environments with cattle's perceptual abilities in mind has the potential to improve both animal welfare and human–animal interactions. A better understanding of how cattle perceive their surroundings can help create environments that are easier to navigate, less stressful, and better adapted to the animals' natural biological needs," says Maria Vilain Rørvang.
