cow with zebra stripes

The quagga was the first extinct animal to have its DNA analysed, and this 1984 study launched the field of ancient DNA analysis. Fly bites are more than an annoyance. “The stripes break up the outline of the animal, which confuses the flies. 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. Painting cattle with zebra-like stripes could be the answer to preventing fly attacks, according to a new study. “Biting flies are the most damaging arthropod pests of cattle worldwide,” the report said. The cows with black stripes and unpainted cows endured over 110 fly bites while the black-and-white cows only suffered less than 60 bites. Recently, Japanese researchers decided to see if painting stripes on cowswould result in fewer fly and other insect bites. The study, published by Japanese scientists in the journal Plos One, found fly attacks were “significantly reduced” by the disguise. According to a new study published in PLOS ONE, when Japanese researchers painted zebra-style stripes on cows, biting flies bothered them half as much than cows without stripes. Two of the cows were painted with white stripes, two with black stripes and two were left unpainted for a control. Matanel Rot , 26/10/19 23:36 Six Japanese Black cows were involved in the study with different paint designs; treatments included black-and-white stripes, black stripes and no stripes. Painting a cow to look something like a zebra has been found to reduce fly bites by 50%. The scientists that turned a cow into a zebra Scientists discover the real reason for the fashionable selection of zebra stripes. But researchers believe this is the first time cattle have been painted and studied in such a way. We found that painting zebra-like stripes on cows can decrease the incidence of biting flies landing on individuals by 50 percent. The water-based paint faded within a few days, so while it's a less invasive solution than a pesticide-laced ear tag, it's a short-term one. The cows were most lucky when they got the white zebra stripes. “Olfaction is also used by the biting flies to find hosts so painting stripes does not completely remove them,” he added. These cows are dressed up to look like zebras, but not because they’re in the moo-d for Halloween. a CONT: no stripe cattle, B&W: black-and-white striped cattle with white lacquer, which indicates “striped-cattle” indicates “striped-horse (zebra)” in Japanese), B: black-striped cattle with black lacquer. The experiment lasted nine days in total, with each cow once white, once black and once without any stripes. While cows that were either unpainted or painted with black stripes were found to have around 120 bites in a 30 minute period, cows painted with black and white stripes tended to have fewer than 60 in the same period. This study examined whether painting zebra-like stripes on domesticated cows can prevent biting fly attacks. Plus, Make like a zebra to avoid insect bites, scientists say. A recent paper describes how a group of scientists painted zebra stripes on cows. “This phenomenon has been explained as modulation brightness or polarized light,” the authors wrote. While the unpainted cows had an average of 128 fly bites, the cows with zebra stripes had only 55. So, taking their zebra research findings to a more practical level, the scientists decided to expand their research to “black and white striped cattle.” They got three groups of black cattle. The stripes were drawn freehand, using “commercial waterborne white lacquers” that faded easily. Scientists then watched the animals. The process then repeated so, over nine … In what was a five-minute process for each animal, researchers painted white, 4cm to 5cm stripes on six pregnant Japanese black cows. Photo Source: New York Post Based on the report, the zebra-striped cows fend off pests. A team of Japanese researchers recruited six cows and gave them each black-and-white stripes, black stripes and no stripes. The research report, “Cows painted with zebra-like striping can avoid biting fly attack,” was carried out by Kojima T., et al and published in PLOS ONE, October 2019. The white-striped cows sustained only half as many bug attacks as either of the other groups. Moreover, zebra-striping reduced fly-repelling behaviors by about 20%, indicating that the cows were less bothered by the insects. Instead of using pesticides, painting cows with zebra-like stripes led to 50% reduction in the number of biting flies. Biting flies are serious livestock pests that cause economic losses in animal production. “Direct comparisons of painted cattle with zebras in field experiments would be useful. Make like a zebra to avoid insect bites, scientists say While unpainted cows and cows with black stripes endured upward of 110 bites in 30 minutes, the … “The economic impact of biting flies on the United States cattle production was estimated at $2.2bn per year. (Paint fumes apparently were not enough to deter flies, since black-striped cows were bitten just as often as the control group.) “We found that painting zebra-like stripes on cows can decrease the incidence of biting flies landing on individuals by 50 percent,” the study concludes. There was over 50% reduction in… Updated 1519 GMT (2319 HKT) October 8, 2019. (CNN)A cow's days of fly-shooing and hoof-stomping might soon be over. The scientists believe the striped pattern confuses the fly’s motion detection and deters the pests. A group of agricultural researchers are giving cows zebra-like … This study took these findings in the clever direction of direct application to livestock animals. When helpless cows are the victims of fly bites, it stings the humans who own them, too. Zebra Botswana by Paul Maritz via Biting flies do considerable damage to cattle and you might say they are the bane of a cow's existence. Painting cows with zebra-like stripes may be a simple strategy to keep biting flies at bay. The researchers now say more work is needed, both to confirm the link and to develop less labor-intensive ways of ensuring cows remain patterned and zebra-like. They'll bunch, or group close together, to prevent fly attacks, which can increase their risk of heat stress and injury. I know I’ve seen horse flies chasing slowly driving cars, for instance. Only 55 flies were observed on the zebra cows, compared with 111 on the black-painted cows and 128 on the control cows. I think it makes sense and could be useful for farmers in the future.”. 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. Ranchers would need to spray down thousands of cows multiple times a week for best results. “In future the development of more effective techniques to ensure the persistence of black-and white stripes on livestock during the biting fly season (3-4 months) may be necessary.”. Zebra-striped cows might not look like the African wild horse, but they get the same benefits from their coloring. Biting flies cause huge problems for cows, but scientists may have found a very strange way to combat the problem. While unpainted cows and cows with black stripes endured upward of 110 bites in 30 minutes, the black-and-white cows suffered fewer than 60 in the same period, researchers found. If so, it could ease one of the most persistent pest problems that face cattle. Insect bites can be significantly cut using a cunning disguise, researchers find, Fri 11 Oct 2019 01.29 BST All rights reserved. “March flies and other biting flies have huge eyes and vision is important for finding animals to bite and suck their blood,” he said. But fewer bites would improve the health of the cows, which would benefit the economy. Previous studies have found that flies are less likely to land on horses wearing striped blankets and other objects painted with stripes. “They are looking for big, dark, moving shapes. The apparent effects of the stripes were remarkable. It was stated that the Zebra stripes were exquisite in nature and that helped in sending away the problem causing insects.

The next step after field experiments is to understand better how the fly eye works with physiological data, what it really sees or not in terms of the stripes, in order to refine the colour pattern. The ersatz zebras were observed to demonstrate only 40 fly-repelling behaviours (such as flicking their tails and shaking their heads) every 30 minutes, compared with 53 and 54 fly-repelling behaviours in the others. published by Japanese scientists in the journal Plos One. A Japanese Black cow painted with zebra stripes. But Bayless said researchers needed to take the next step and address smell as well as sight. All it takes to repel pests is a new paint job, researchers say. Researchers tested their theories on 6 Japanese Black cows by either painting zebra-like stripes (black-and-white, see cow ‘a’), painting only black stripes (cow ‘b’) or … The laquered bovines were then observed. Meanwhile, the test subjects with the black and white stripes were bitten 60 times in the same time period. Researchers believe painting stripes on to cattle is a world-first and could become an environmentally friendly alternative to pesticides. As a result, cows painted with white stripes showed 20% reduction in fly-repelling behaviour. Biting flies interfere with cows' grazing, feeding and bedding, and they're estimated to cost the cattle industry. In the study, one cow was painted like a zebra with white spray paint, one was given black stripes, and the third was left as it is to confirm which received more bug bites. A team of researchers painted Japanese black cows with black-and-white stripes as part of the experiment based on the observation that the stripes on zebras seem to … It confirmed that the quagga was more closely related to zebras than to horses, with the quagga and mountain zebra (Equus zebra) sharing an ancestor 3–4 million years ago. Number of biting flies on legs and body (a) and the frequency of total fly-repelling behaviors (b) of the experimental cows. Since they can't swat flies away, cows exert significant energy to avoid them, researchers said. The process then repeated so, over nine days, each cow spent three days striped, painted black or unpainted. Flies stop cattle from grazing, feeding and sleeping, and can cause “bunching behaviours”, where cattle jostle for space to escape flies, causing heat stress and injury. Painting cows with zebra-like stripes may be a simple strategy to keep biting flies at bay. Stripes help cows avoid pesky fly bites, a new study found. But the results of going zebra were undeniable. Cows are being painted with zebra stripes to test odd theory - and it works. Last modified on Fri 11 Oct 2019 14.30 BST. The cows with black lines were bitten 111 times on average. Keith Bayless, a postdoctoral expert in fly biology at Australia’s CSIRO, welcomed the research and said the hypothesis – that stripes affected the flies’ vision – made sense. That method involves painting the cows with zebra-like stripes, which help camouflage the animals from annoying pests. © 2020 Guardian News & Media Limited or its affiliated companies.
