Standing in front of a herd of cows with a shotgun microphone and headset is Alexandra Green, a PhD student at the University of Sydney Faculty of Environmental Science.
Green's motivation for this study came from a
Green, who spends time with cows on the ranch on the campus, said, 'My friends and family seemed to be a little funny.' Worth Partly, we were able to record 333 calls of cows called 'high frequency utterances'. Also, in that case, not only `` which individual made the cry '' but also `` positive '' situation such as when you can find delicious food, `` negative '' such as when you have left other cows Was recorded.
Then, we analyzed the data of cow's call using two methods:
In addition, Mr. Green conducted further analysis and found that the cows used the same tone when they sang in any situation, and the tone was different for each individual. Green says of this result: 'The cows not only transmitted their emotions through the bark, but also had a personality in the voice. It is very likely that the herd of cows could identify each other through the bark. It ’s expensive. ”
Also, Professor Cameron Clark of the University of Sydney, co-author of the dissertation and coach of Green's research, said, 'The research of Ally (Green) has been really inspiring. It was only known that the cow's voice had a personality, but this discovery has confirmed that the personality of the cow's call has been an identity in the herd throughout his life. '' Commented.
Green says he hopes to use the findings in this study to improve animal welfare and productivity in dairy farming.
