|
|
Term
| Abomasum called glandular stomach because... |
|
Definition
| it’s similar to our stomach |
|
|
Term
| why the liquid and gas are split in the ruminant stomach |
|
Definition
|
|
Term
| Each compartment of the ruminant stomach has a different... |
|
Definition
|
|
Term
| The omasum is kinda like a... |
|
Definition
|
|
Term
| the first part of the ruminant stomach forage goes to after consumption |
|
Definition
|
|
Term
| why consumed forages first go to the reticulum after consumption |
|
Definition
| because the animal doesn’t have time to chew it |
|
|
Term
| why forage that goes to the stomach needs to be rechewed |
|
Definition
| so that fermentation can be more efficient |
|
|
Term
| what happens to the forage that goes to the reticulum? |
|
Definition
| undigested plant matter is compressed & then regurgitated |
|
|
Term
| what happens in the rumen? |
|
Definition
| Microbial fermentation of cellulose |
|
|
Term
| the function of papillae in the stomach |
|
Definition
| Papillae in the rumen increase the surface area of the stomach to absorb products of fermentation |
|
|
Term
|
Definition
| basically a fermentation vat |
|
|
Term
| Ruminal Tissues are ______ epithelia |
|
Definition
|
|
Term
| Epithelium in ruminants possess multiple layers, referred to then as... |
|
Definition
| stratified squamous epithelium |
|
|
Term
| functions of the cells in the ruminal tissues of ruminants |
|
Definition
| Cells perform several functions including nutrient exchange and protection |
|
|
Term
| what happens in the omasum? |
|
Definition
| water is reabsorbed from the digested fluid that passes through the reticulum |
|
|
Term
| which has more epithelia? omasum or rumen? |
|
Definition
|
|
Term
|
Definition
| releases pepsin & acids for typical protein digestion |
|
|
Term
| what is between the abomasum and the small intestine? |
|
Definition
|
|
Term
| function of the pyloric sphincter |
|
Definition
| controls how much is going into the small intestine |
|
|
Term
| function of mucousal tissue of abomasum |
|
Definition
| secretes enzymes to assist in lipid and protein degradation |
|
|
Term
| Microbes that pass from the rumen will be digested in the... |
|
Definition
|
|
Term
| the absorption that happens at the microvilli in the abomasum |
|
Definition
| Microvilli in intestine are sites for passive (lipid) or active (peptide) absorption of nutrients. |
|
|
Term
| something present in the digesta taken from sheep |

|
|
Term
| what ruminal bacteria do to plant material in ruminant stomachs |
|
Definition
| they associate with cell walls of the plant tissues, attach via mucilagenous excretions, and excrete digestive enzymes that degrade the fiberous fractions of the cell wall. |
|
|
Term
| Bacteria do this to break down the cell wall of plant material |
|
Definition
| secrete enzymes, which help break down the cell wall |
|
|
Term
| The composition of the cell wall is important for... |

Definition
| the composition of the cell wall |
|
|
Term
|
Definition
| the conversion of forages into energy |
|
|
Term
| Bacteria secrete enzymes that help... |
|
Definition
| break down cell walls and release cell contents |
|
|
Term
| Grass better for ruminants because... |
|
Definition
| that’s what they’re naturally designed for |
|
|
Term

Term
| close ups of the lining of the parts of the ruminant stomach |
|
Definition
|
|
Term
|
Definition
| Damage to the gut structure, as can be caused by excess organic acid production in the hindgut, appears as mucin casts in the manure, indicating the gut lining is being stripped off. |
|
|
Term
|
Definition
| Large-intestine damage and increased organic acids in the gut lumen may play a role in diarrhea often seen with ruminal acidosis. Bubbling is a result of post-defication fermentation |
|
|
Term
| something that may cause mucin casts and diarrhea and bubbling |
|
Definition
|
|
Term
| How do we know how much energy is in the forage that is being consumed, and how do we know we are meeting the needs of the animal? |
