Painting Cows To Look Like Zebras Has A Surprising Benefit

[Swordsmyth]

Scientists in Japan have discovered a clever way to reduce the need for using pesticides on livestock ― and the evidence supporting it is pretty black and white.
A study published in the journal PLoS One found that painting zebra-like stripes on cows significantly reduced attacks by biting flies, providing a means of defending livestock against flies without pesticides.
The study’s inspiration came from past experiments that suggested the striped coats of zebras ― and black and white surfaces in general ― attracted fewer flies than the solid black color of the Japanese bovines that were studied.
Flies are less likely to land on black and white surfaces due to the polarization of light, which impairs their perception, according to the study. Researchers found that the zebra-painted cattle were bitten nearly 50% less than solid-black animals.


Fly bites are more than an annoyance. The insects interfere with cattle grazing and feeding, increase fly-repelling behaviors like foot stamping and head throwing, and cause cattle to bunch together, which increases heat stress and risk of injury, researchers said. Fly bites are estimated to cost the livestock industry billions every year.

Maybe the 50% reduction in bites is because 50% of the cow is painted and if they painted the other 50% of the cow, they would be bitten nearly 100% less than solid-black animals.

I think solid white cows get bitten too.

Maybe they should try checks instead of stripes.

Myabe flies don't like to bite through the paint.

Myabe flies don't like to bite through the paint.

I doubt the paint provides a solid barrier but it could be.

The article says the patterns confuse the flies.

ding ding ding. Also, the paint could have some repellent effects on its own. They should have had a control to exclude those other possible factors

So that's why no my fruit stripe gum comes fly-free!

Japan could make flies illegal.

Works to repel sharks as well.

The same scientists also discovered that it was somewhat cheaper and
just as effective to cut up some of Michelle Obama's old canvas muumuus
and fashion them into Cow apparel.
One big cost savings feature was that if they cut them up just so, they
could get one to fit two cows.

I like my cows to look like cows, not zebras.
