Cows with names produce more milk

Daisybell, Buttercup, Maybelline or even Norma. Giving cows a name increases their milk yield.

This surprising insight into bovine motivational psychology by scientists at Newcastle Un

iversity has been rewarded with one of this year’s Ig Nobel prizes, an institution that rewards “research that makes you laugh and then makes you think”.

While the concept sounds somewhat farcical, the study was intended as a sincere investigation into cow welfare. “You’re laughing in the face of science!”

Catherine Douglas, who led the study, said. “The whole study was about how stress and fear can have a biological effect on milk yields.”

However, she conceded she was thrilled to be sharing the Ig Nobel award for veterinary medicine with her co-investigator, Peter Rowlinson.












The study involved 516 dairy farmers in the UK and revealed that the average amount of milk produced by a cow over its annual ten-month lactation period is 13,198 pints (7,500 litres). Cows with names had an average higher milk yield of 454 pints.

Nearly two thirds of farmers in the UK said they “knew all the cows in the herd” and 48 per cent agreed that positive human contact was more likely to produce cows with a good milking temperament.

Almost 10 per cent said that a fear of humans resulted in a poor milking temperament.

“The most important thing is for cows to be treated as individuals,” said Dennis Gibb, a dairy farmer who owns Eachwick Red House Farm near Newcastle upon Tyne with his brother Richard.

“We have got more than 300 cows, and they’re all named after flowers or trees.” However, he said there were limits to their originality when it came to naming, admitting that one cow was called “Holly the 15th”.
