Cows with Names Make More Milk
Robert Roy Britt Editorial Director LiveScience.com
Researchers in the UK say cows with names make 3.4 percent more milk in a year than cows that just feel, well, like cows.
There seems to be more than just names involved, however.
The study, involving 516 dairy farmers and published online Tuesday by the journal Anthrozoos, found that "on farms where each cow was called by her name the overall milk yield was higher than on farms where the cattle were herded as a group," write researchers Catherine Douglas and Peter Rowlinson of Newcastle University.
Nobody likes to be herded. Even a cow, one might presume. Indeed, the findings in fact point to an overall personal touch that - just a guess here - might say as much about the farmers as it does about the cows.
"Just as people respond better to the personal touch, cows also feel happier and more relaxed if they are given a bit more one-to-one attention," Douglas said. "By placing more importance on the individual, such as calling a cow by her name or interacting with the animal more as it grows up, we can not only improve the animal's welfare and her perception of humans, but also increase milk production."
Happy cows. Okay. Well, if you are a farmer (especially one with a small farm that struggles to be profitable by milking only a handful of cows) you probably would not argue with success. Cows, after all (and in case you thinking of judging them as dumb animals) are known to have a magnetic sixth sense and are not as prone to cow-tipping as you might have heard. Who knows what else they are capable of?
Dairy farmer Dennis Gibb, who co-owns Eachwick Red House Farm outside Newcastle with his brother Richard, says he believes treating every cow as an individual is vitally important. "They aren't just our livelihood - they're part of the family," Gibb said in a statement released by the university. "We love our cows here at Eachwick and every one of them has a name. Collectively we refer to them as 'our ladies' but we know every one of them and each one has her own personality."
46 percent said the cows on their farm were called by name.
66 percent said they "knew all the cows in the herd."
48 percent said positive human contact was more likely to produce cows with a good milking temperament.
Less than 10 percent said that a fear of humans resulted in a poor milking temperament.
"Our data suggests that on the whole UK dairy farmers regard their cows as intelligent beings capable of experiencing a range of emotions," Douglass said. "Placing more importance on knowing the individual animals and calling them by name can - at no extra cost to the farmer -- also significantly increase milk production."
