Cows that are named and treated with a “more personal touch” can increase milk production by up to 500 pints a year.

The study, by the university’s School of Agriculture, Food and Rural Development, involved(包括) 516 farmers across the UK.

The study found farmers who named their cows got a 54% higher production than those that did not give their cows names. Dairy farmer Dennis Gibb said he believed treating every cow as an individual(个体) was very important.

“They aren’t just our means of making money. They’re part of the family,” he said. “We love our cows here and every one of them has a name. All of us regard them as ‘our ladies’ but we know every one of them and each one has her own personality.”

Dr Catherine Douglas said, “What our study shows is what many good, caring farmers have long since believed. Our data suggests that UK dairy farmers regard their cows as intelligent beings(智能动物). They are able to experience a range of emotions(情感的领域).”

“Placing more importance on knowing the individual animals and calling them by name can, at no extra cost to the farmer, also increase milk production.”
