Study: Cows painted like zebras fend off flies better


Cows painted like zebras can avoid biting fly attacks

(CNN)) — Zebras’ striped coats may help prevent biting horse fly attacks.

Past studies show that flies are less likely to land on black-and-white surfaces.

Researchers believe it’s because the light distribution can mess up their perception.

To test the theory, cows were painted to look like zebras.

Then Japanese researchers counted the bites.

They found that black cows painted with white stripes experienced 50-percent fewer fly bites.

The research is significant because biting flies interfere with cows’ grazing, feeding and bedding.

Researchers said cows exert lots of energy by grouping together to ward off flies, which increases their risk of heat stress and injury.

So the new study could be key to improving their health and benefitting the economy.

Results were published October 3rd in the journal ‘Plos One.’
