A study published last month in Nature's Scientific Reports found that cows' "voices are individually distinct," and that "they're able to maintain these individual characteristics across the contexts". The research team hopes that "through gaining knowledge of these vocalizations, farmers will be able to tune into the emotional state of their cattle, improving animal welfare".
The recordings included "positive" noises the cows made during "positive" contexts like right before meals as well as "negative" situations, such as denied feed access and during physical and visual isolation from the rest of the herd", a statement from the university explains.
