get microbes to help populate the gut,\u201d says evolutionary biologist Elaine J. Power, now retired in Eugene, Ore. The list of youngsters includes species as varied as koalas, desert tortoises and ostriches. And that\u2019s just one reason why a species might recycle previously eaten meals. She and another evolutionary biologist, Sally Bornbusch, explored vertebrate fecal scientific literature at the Smithsonian National Zoo and Conservation Biology Institute based in Washington, D.C., during internships with zoo clinical nutritionist Erin Kendrick.<\/p>\n\n\n\n<p>As food, says Power, \u201cpoop is a wonderful source if you don\u2019t care about being infected by diseases and parasites.\u201d Some species can\u2019t live without it. Pikas may make it through harsh winters by <a href=\"https:\/\/www.sciencenews.org\/article\/pika-yak-poop-winter-slow-metabolism-yak-biology\">relying on yak poop<\/a>. But among the most extreme are cavefish that can\u2019t fly out to forage, so depend heavily on guano from bats that can.<\/p>\n\n\n\n<p>\u201cRats are fun, if you happen to have a particular sense of humor,\u201d Power says. Up to 40 percent of their food intake comes from eating poop. \u201cIf you stop them from doing it, they get vitamin B12 deficiencies \u2014 they get sick.\u201d It\u2019s something laboratory keepers have to watch.<\/p>\n\n\n\n<p>For rabbits and a variety of other small animals with plant-rich diets, poop-eating serves as a digestive workaround for not being a cow, whose stomachs have extra compartments. By the time the cow\u2019s meal reaches the intestinal zone for nutrient absorption, big tough molecules have become tidbits in easy-to-absorb slosh. For rabbits and many other small creatures, eating food that\u2019s been through a gut once, aka poop, works as an alternative way for getting hard-to-extract nutrition.<\/p>\n\n\n<div class=\"wp-block-image  has-alignleft\">\n<figure class=\"alignleft size-full\"><figcaption class=\"wp-element-caption\"><span class=\"caption wp-caption-3148029\">A capybara bends around to lick up special lumps of waste that are microbe-rich and especially soft and fine-grained for a second try at extracting nutrients.<\/span><span class=\"credit wp-credit-3148029\">M. Polotzek et al\/<em>Mammalian Biology<\/em> 2023<\/span><\/figcaption><\/figure><\/div>\n\n\n<p>Poop-eating takes a special form in some of these non-cows. \u00a0A bit of the intestinal pathway, called the caecum, catches some of the waste as softer, finer-grained masses that an animal, as Power puts it, then \u201ccan lick off its anus.\u201d A paper cited in the new review includes portraits of a <a href=\"https:\/\/link.springer.com\/article\/10.1007\/s42991-023-00376-1\" target=\"_blank\" rel=\"noopener\">capybara in a yoga pose\u2013like body twist<\/a>, angling into position to eat caecal lumps.<\/p>\n\n\n\n<p>Eating poop can also show up as part of parenting. While tending frail new hatchlings, a parent swift for instance will now and then search out and gulp down a saclike dropping. Sanitation? Thirst? It\u2019s hard to tell for birds on a nest, but Power suspects that both motives apply for lactating black bear mothers alone in a den with a cub too young to tag along foraging.<\/p>\n\n\n\n<p>Human coprophagy doesn\u2019t surface in the zoo team\u2019s review of other animals. But biochemist and historian Sachi Sri Kantha in Tokyo, retired from Gifu University in Japan, has published on its possibilities. Some traditional medicines include fecal elements and could be swallowed. Western medicine now uses fecal microbes in gut-related therapies, but they\u2019re inserted colonoscopy-style instead of being truly eaten. Supposed <a href=\"https:\/\/www.sciencenews.org\/blog\/scicurious\/fecal-transplants-regulation\">fecal ingestion<\/a> shows up on the internet now and then, but Sri Kantha doesn\u2019t treat this as very informative. \u201cSome people will do anything for money,\u201d he says.<\/p>\n\n\n\n\n\n\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/animal-food-coprophagy-nutrients-poop\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>Feces don\u2019t get enough credit as food.
