Ruminant stomach
| Term | Definition |
|---|---|
| Name the four chambers of ruminant stomachs in order | Rumen, reticulum, omasum, abomasum |
| Largest compartment of stomach | Rumen |
| Compartment where most digestion occurs | Rumen |
| Which compartments contains papillae? | Rumen, Omasum |
| Where do the most micro organisms live? | Rumen |
| What is the purpose of micro organisms? | Break down and ferment food |
| What is synthesized by the micro organisms? | Protein, vitamin B and K |
| What compartment has a honeycomb structure? | Reticulum |
| Function of the reticulum | Gather digestia to be rechewed and reswallowed |
| Define hardware disease | When an animal eats something that punctures the reticulum (typically metal) and it gets infected |
| How is hardware disease treated? | Magnets or surgery depending on severity |
| Function of omasum | Water and VFA absorbtion |
| Structure of omasum | Many folds that increase surface area |
| Function of abomasum | Use enzymatic digestion to continue to break down food |
| 4 Rs of rumination in order | Regurgitation, resalivation, remastication, redeglution |
| What is a ruminant? | An animal with a four-chambered stomach |
| What is a monogastric? | An animal with a single-chambered stomach that uses solely enzymatic digestion |
| Four layers of ruminant stomach | Gases, microbes attached to mat, microbes attached to wall, microbes in solution |
| Is full of food particles | Microbes attached to mat |
| Has saliva and digestive juices | Microbes in solution |
| Epimural bacteria | Microbes attached to wall |
| What is so amazing about ruminants? | They can graze hard farmland into something usable and synthesize nutrients out of it |
| Where should the pH for a ruminant stomach be? | 7 |
| What heightens pH? | Eating food |
| What lowers pH? | Digesting food |
| What is ruminant nutrition really about? | Feeding and keeping the microbes happy |
| Most abundant microbe | Bacteria |
| Microbes that create lactic acid | Bacteria, Fungi |
| Microbes that eat lactic acid | Protozoa |
| Microbes that break down hard-to-digest plants | Fungi |
| Microbe that produces methane | Methanogenic archea |
| What do all microbes seek to produce? | Volatile Fatty Acids (VFAs) |
| What is the function of VFAs? | To provide nutrition to the ruminant |
| Where do most VFAs go after entering the bloodstream? | Liver |
| What is the function of the liver? | Convert VFAs into useful products |
| What is acetate used for? | ATP and lipid production |
| What is propionate used for? | Glucanogenisis |
| What is butyrate used for? | Oxidized for energy |
