Painting ‘Zebra Stripes’ on Cows Wards Off Biting Flies
7th October 2019
And so, the researchers painted six Japanese Black cows with black-and-white stripes, which took just five minutes per cow. They then observed the cows for three days, taking high-resolution images of them at regular intervals to count the insects on the animals and also recording any fly-repelling behaviors like leg stamping, tail flicking, and skin twitching. The same cows were also observed for three days with painted-on black stripes (to see if it was the paint chemicals, not the coloring, that repelled flies) and and with no stripes at all.
The apparent effects of the stripes were remarkable. The number of biting flies observed on zebra-striped cows was less than half the number seen on unpainted cows and far less than cows painted with black stripes. Moreover, zebra-striping reduced fly-repelling behaviors by about 20%, indicating that the cows were less bothered by the insects.
Well, then, all we need do is breed some striped cows.
