1. What is digestion breaking down process of food to allow absorption 2. What are the three types of digestion? Mechanical chemical and microbial 3. What is chyme? Food after hydrochloric acid breaks it down 4. what does it mean to be a monogastric? One stomach 5. what animal is a monogastric? Swine 6. what does it mean to be a modified monogastric? A single stomach but specialized components that aid in digestion 7. What animal is a modified monogastric? Horses 8. how does mechanical digestion work? Breaking down the cell wall 9. how does chemical digestion work? Enzymatic, enzyme that is released is hydrochloric acid 10. How many days does it take for the Rumen to be functional? Eight to 60 days 11. What is colic? And what animal is it seen in most commonly? When the small intestine is twisted or plugged up, horses 12. what is founder? When the hoof walls curve in 13. what does the mouth secrete? Water, mucin, bicarbonate salts 14. What is mucin? Lubrication aid for swallowing 15. what are bicarbonate salts? Acts as a buffer to regulate stomach pH 16. What are the mouth differences in swine versus ruminants? Swine secrete salivary amylase, ruminants don't secrete any enzymes, but they do provide a source of nitrogen phosphorus and potassium 17. What is acidosis? When the pH drops because of too many readily digestible carbohydrates are ingested 18. what is the function of the esophagus? Ingested material moves with muscular contractions also known as peristaltic waves 19. what are the differences in esophagus functions between horses and ruminants? Horses only have one-way peristaltic waves, ruminants have two way movement that allows for regurgitation and chewing of the cud, young ruminants also have an esophageal groove 20. What are the four compartments of the stomach in ruminants? Reticulum, rumen, omasum, abomasum 21. Why does the reticulum have a honeycomb-like surface? It expands and contracts 22. describe the reticulum. It is not completely separated from the rumen and the walls are lined with mucus membranes 23. Describe the Rumen. A large hollow muscular compartment which extends from the diaphragm to the pelvis and almost fills the entire left side of the abdominal cavity 24. What are the walls of the room and lined with? Papillae 25. What are the functions of the rumen? Storage, soaking, physical mixing and breakdown, bacterial synthesis of water soluble vitamins and vitamin K as well as deamination reactions 26. What does the rumen provide the bacteria? Warm, moist, dark anaerobic conditions, proper pH a 6.8, substrate 27. What do bacteria provide the rumen? Volatile fatty acids, microbial crude protein, vitamin K, B vitamins, and combines nitrogen from dietary protein to a carbon skeleton from carbohydrates to form their own body protein 28. what are the three main energy sources in a ruminant diet? Propionate, acetate, butyrate 29. when is acetate high? In grazing animals 30. when is propionate high? Provides energy, (glucose), higher in grain fed animals 31. How is butyrate changed? Does not change no matter how much or what we feed 32. What is the crude protein percentage in corn? 10 to 12% 33. what is the crude protein in cotton seed meal? 8 to 41% 34. what is the crude protein in urea? 281 percent 35. what is transfaunation?

If CO2 from the rumen cannot be released, what happens? Bloat 39. What is bloat? When gasses produced by the rumen cannot be released and can result in death for the animal because of compression against the diaphragm 40. What can you do when an animal is bloating? Give mineral oil to break the tension 41. What is the urea cycle? Mechanism that takes nitrogen across the room and wall back to the salivary glands in order to preserve nitrogen in the system 42. what nutrient do you have to have for the urea cycle to work? Carbohydrates, carbon skeleton 43. true or false, monogastric have a urea cycle no monogastrics do not have a urea cycle 44. Good to know, put urea in molasses block and then they get the nitrogen and carbs, and all is good 45. What are the functions of the omasum? Absorption of water, filter 46. what is the function of an esophageal groove? Allows milk consumed by young animal to bypass the Roman and escape bacterial fermentation and go straight to the abomasum and is digested by rennin 47. what is colostrum?

What product is used to prevent ulcers in horses? Ulcer guard, the same thing as pepto, takes the pH down in the stomach 55. What is gastrin? A hormone that causes the release of digestive enzymes 56. when is gastrin released? During stomach distension (getting full), the presence of partially digested proteins especially amino acid, hypercalcemia, released when thinking about food/hungry 57. when is gastrin inhibited? When there is presence of acid in the stomach, hydrochloric acid gives negative feedback to gastrin 58. What is hydrochloric acid secreted by? Parietal cells 59. What does Hydrochloric acid activate?
