A new study has sparked excitement in the scientific world by showing that cows can purposefully use tools, challenging previous assumptions that these animals have cognitive limitations.
The research, published in the journal Current Biology on 19 Jan 2024 GMT+7, documents the first official case of tool use by a cow. The subject is Veronica, a Swiss Brown cow living in a village in Carinthia, raised like a family member by her organic farmer owner.
Scientists found that Veronica intentionally uses a brush and sticks. She selects the stiff-bristled end of the brush to scratch her broad, sturdy back, while for more delicate areas like her belly or lower body, she switches to the smooth handle. She also adjusts her movements—force, speed, and direction—to suit each area.
Researchers describe this as flexible, multifunctional tool use, a behavior seen in only a few animal species besides humans, such as chimpanzees. Although cows must use their mouths instead of hands to manipulate tools, Veronica astonishingly compensates for this physical limitation.
The research team believes that Veronica's unique living conditions—longer lifespan, human interaction, and access to varied open spaces—are key factors that encouraged exploratory and advanced learning behaviors.
Scientists are inviting other farmers and cattle keepers who have observed similar behaviors to contribute additional information.
