![]() ![]() But its propagators suggest that the process has helped many cows live healthy lives as long as up to 12 to 15 years. Various animal activists have opposed the farming practice across countries. The rumen is stitched to the lining of the body, and this fistulation allows researchers to examine the contents of the stomach as well as study the digestive processes of the cow. The entire procedure is performed under anesthesia, and the cow heals in about four to six weeks. Photo: Mizzou CAFNR/Flickr The Risk of Surgery Getting to know the inside of the ruminant. The surgical insertion is also used to study the bodily processes of bovines, put food matter into their stomach as well as get it out for analyses. A healthy cannulated cow thus becomes a donor among cattle, serving sick cows and even goats and lambs with healthy bacteria for their recovery. ![]() The rumen fluid and microbes are then transferred to the body of the ill cow. A cannula or a sturdy tube is inserted into the opening, and is used to obtain the microbes from the healthy cow’s body. In a cannulated cow, a porthole is inserted into the side of its body to obtain rumen bugs for treatment of ill cows. Now imagine if a cow got sick and lost the homeostasis that allowed good bacteria to nurse it back to health. The symbiotic relationship allows the cow to thrive despite eating whatever it does, and lets the microbes exist in exchange for their positive effect on the mammal’s gut health. Of its four stomachs, a cow’s rumen is where this magic happens-cellulose from plants is converted into energy in the 20-gallon pit. Within a cow live millions of independent microorganisms that work day and night to fuel its digestive system. Photo: Modern Farmer What is a Cannulated Cow? Whatever the reason, we’re almost a century ahead and the practice continues to remain highly moot.Ī cannulated cow. Since then, scientists and agriculturalists across the world have furthered the controversial practice to improve the health of cattle, reduce mortality rates and increase the output of milk. In 1928, Arthur Frederick Schalk and RS Amadon of North Dakota Agricultural College became the first men to eagerly peep inside a cow with a porthole studded on its body. Call it curiosity, or the craving to reveal all of the world’s truths, but the cannulated cow is man’s experiment to discover what goes on in the digestive systems of a bovine, and how best its milk output can be increased to its maximum potential. Either system allows the manager a glance into what is actually happening in their respective models of consumption, and maybe a more direct route to analysis than testing is a system of feedback, the likes of which are being explored by systems like Socrative.Imagine being able to look inside a cow. The educator is not there consuming with the students and so the level of digestion is a mystery. While educators would likely suffer if they thought of their students as grazers of knowledge and learning, they may be able to see that not all feedback gained from testing is indicative of learned material. This app also acts like the window into the weird digestion by students, hence an interesting tool of feedback like the fistulated cow. Socrates supported a method of teaching that engaged the students in a manner that would inspire critical thinking, this app is an homage to that. Often the plug that seals this tunnel looks like a window on the side of a cow. This window is created by making a tunnel into one of the cow’s stomachs and creating an access point that will not interrupt the digestion of the cow. One tool that farm managers and veterinarians can use to manage a herd of cattle is to create a window into what they are consuming and how they are digesting it. conceptual and functunional understanding in a classroom, based on the various levels of interfacing between the app and the class. This app is another way to gauge engagement, and. One fellow student brought up an app, Socrative, that they use in class to find out just what content their students are digesting and what cud they have to chew further to be able to digest. In class so far, we have been discussing connected learning, and as a side note, testing, and how the culture or education relies so much on the final test grades of students as a feedback for educators. You may be saying “what is a fistulated cow,” or you may be wondering about Socrates and cows. ![]()
