Cows CHAT with each other about food and weather and can even express emotions, study finds
Cows have their own language and talk to each other about food and weather, according to a new study by scientists in Australia.
They created a software program called “Google Translate for cows” to get a better idea of what the heifers said when they went “nicer.”
The research, by a PhD student from the University of Sydney, discovered that dairy cows also respond to positive and negative emotional situations.
Cows each have their own individual voice and link their moods to their “moos,” said lead author Alexandra Green.
Biologists made the discovery by listening to Holstein-Fresian heifer cattle, a European breed, howling in a microphone and analyzing the field.

Alexandra Green at Mayfarm, Camden. She picked up dozens of cows to record their pitch and discover how they communicate
Mrs. Green and her team discovered that each cow retains its own clear beauty and can give directions in various situations that help them stay in touch with the herd.
The team discovered that they can also express excitement, excitement, involvement or fear.
“We discovered that the vocal individuality of cattle is relatively stable in various emotionally charged agricultural contexts,” the lead author said.
The findings can help farmers keep their cattle healthy and happy by understanding the mood of each cow by translating their individual moos.
Some research has already been done into communication between cows.
A previous study showed that mothers and offspring of cattle are known to communicate by maintaining their individuality in their down.
The new study confirms that cows continue to roar this individual throughout their lives, even when they are muttering.
Dairy cows communicate with each other all the time, but when they talk about happier things, such as food, their moos are sonorous, Mrs. Green said.
When they complain about the weather, their moos, while still retaining their fingerprint-like individuality, are lower.
“Cows are social, social animals,” said Green, who will use this research as part of her dissertation.
‘In a sense, it is not surprising that they assert their individual identity throughout their lives and not just during the printing of mother calves.
“But this is the first time we’ve been able to analyze voice to have convincing evidence of this trait.”
Groups of curious cows come for a close-up. The research, by a PhD student from the University of Sydney, discovered that dairy cows also respond to positive and negative emotional situations
Scientists included hundreds of ‘moos’ from 13 Holstein-Frisian heifers in the study using acoustic analysis programs with the help of colleagues in Italy and France.
The findings suggest that farmers should integrate knowledge of individual cow voices into their daily farming routines, Mrs. Green said.
‘We hope that by acquiring knowledge about these vocalisations, farmers can adjust to the emotional state of their cattle and improve animal welfare.
“By understanding these vocal characteristics, farmers can recognize individual animals in the herd that may require individual attention.”
The researcher traveled to France to analyze the vocal properties of the cattle in Saint-Etienne, in collaboration with leading bio-acoustic experts, including co-authors Professor David Reby and Dr. Livio Favaro.
Her research will be included in her PhD, which investigates vocal communication and the use of livestock in dairy farms.
The researcher, who started the research in 2017, says that one day she hopes to become a “cow whisperer” and make an English to cow dictionary.
The study was published in the journal Nature.
WHY ARE COWS BAD FOR THE ENVIRONMENT?
The animals are notorious for creating large amounts of gas, which makes an important contribution to global warming.
Each of the farm animals produces the equivalent of three tons of carbon dioxide per year and the amount of animals increases with the growing need to feed a thriving population.
Methane is one of the most powerful greenhouse gases and retains 30 times more heat than the same amount of carbon dioxide.
Scientists are investigating how feeding different diets can make livestock more climate-friendly.
They believe that feeding seaweed to dairy cows can help and also use a herb-rich food called the Lindhof monster.
Researchers discovered that methane emissions from a cow were reduced by more than 30 percent when they ate ocean algae.
In research conducted by the University of California in August, small amounts of it were mixed in the feed of the animals and sweetened with molasses to hide the salty taste.
As a result, methane emissions decreased by almost a third.
“I was very surprised when I saw the results,” said Professor Ermias Kebreab, the animal scientist who led the study.
“I didn’t expect it to be so dramatic with a small amount of seaweed.”
The team is now planning to conduct an additional six-month study of a seaweed diet in cattle from this month onwards.
