What is cow hair paint like zebra? Why is the way to protect the environment?
According to a recent study published in PLOS ONE, scientists have proposed a strange project: zebra-like cow paint, whose purpose is to protect the environment.
All explanations are based on the hypothesis, the most common of which is that the stripes are responsible for scattering heat, helping zebras to regulate their body temperature in hot African weather. However, this hypothesis has been proved to be incorrect by the experiment.
After the above test, two more theories were considered to be quite relevant regarding this zebra coat. First, the zebra fur is a very special method of camouflage, which will create a visual illusion when they run and make the pursuers feel dizzy.
The second hypothesis involves distracting blood-sucking bugs: the reflected light in the black and white hair area is different, so the insects will have a geolocation noise and they will avoid the fur.
Based on these two theories, scientists in Japan have proposed the idea of painting fur for zebra breeds. Specifically, experts painted a zebra coat for a group of cows, painted black stripes for another group of black cows, and left a group without any repairs. They then observed their fly-chasing behavior (wagging their tails, waving their ears), the number of flies and insects, counting each peanut and recording it.
Results showed that the “zebra” cows had a 50% lower rate of flies attack compared to the black and unpainted groups (the other two groups had no difference). In addition, the number of times they have to perform “chasing flies” of the zebra group is also less than 20%, because they are no longer bothered by bugs.
But what does that have to do with protecting the environment? It turned out to be completely related. The research team believes that this result can experiment on a large scale since current methods of killing flies when using cattle are mainly pesticides.
Zebra paint for cows is not only cheaper but also less toxic, makes them healthier and does not pollute the environment. This is a great alternative for pesticides, improving the quality of life for cows and non-toxic to humans. On top of that, it also eliminates the resistance of pests to insects.
