The cecum of the horse and rumen of the cow use very different processes to ferment feeds T/F - correct answer False Horses require a higher quality source of proteins in their feeds than cows because - correct answer The cecum produces lots of high quality proteins , but these are not absorbed into the bloodstream as they move downstream into the. large colon Horses were derived from a primitive mammalian class called ___. - correct answer Perissodactyls The hindgut of the horse is composed of the following segments: - correct answer Cecum, large colon and rectum If a cup of glucose was fed to a horse, it would enter the small intestine as intact molecules that are then absorbed through the small intestine villi into the bloodstream, causing an immediate rise in the blood glucose level. - correct answer Feeding glucose to a cow would not raise glucose levels in the blood because all of the glucose would be fermented into other products in the rumen before it had an opportunity to enter the intestines. After fermentation of feeds in the cecum, the primary nutrients absorbed by the equine large colon are; - correct answer Volatile Fatty Acids Which of the following feeds would not be considered a "concentrate"?

Are released by the epithelium of the gut into local capillaries Are bacterial products that can increase vascular permeability and cause circulatory collapse are dangerous even when they are released into an intact and healthy gut. are contaminants of many feeds, including hay This is your recorded answer from classroom or homework - correct answer Are bacterial products that can increase vascular permeability and cause circulatory collapse Auscultation is defined as... - correct answer listening to internal sounds with a stethoscope Which of the following statements about gut motility is incorrect? Hypermotility is generally more likely to cause a severe colic than ileus. Severe hypomotility is similar to ileus. Ileus causes bloat through excessive fermentation and gas production Prolonged ileus can result in excessive localized gas production and rupture of the gut wall - correct answer Hypermotility is generally more likely to cause a severe colic than ileus. Upon passage of a stomach tube into a horse, you notice that a great deal of air rapidly exits the tube (i.e., you just decompressed the stomach). Which of the following statements is true? The horse has a blockage of its gut, probably in the section of intestine close to the stomach. You need to administer several gallons of fluid through the tube ASAP. You may safely pull the tube and allow the horse to "burp" out any excessive gas through its esophagus. Excessive air in the stomach indicates rupture of the diaphragm. - correct answer The horse has a blockage of its gut, probably in the section of intestine close to the stomach. Which of the following management strategies will NOT increase the risk of colic in a herd of horses? The horses have free access to average quality hay. The horses are fed all of their concentrate ration once per day. The horses are not allowed outside during the winter. The horses are treated "organically", so chemical deworming is not performed on the herd. - correct answer The horses have free access to average quality hay. (T / F) Most diagnosed equine colics will require a surgical correction. Select an answer and submit. - correct answer F
