Name the 5 parts of the cow's digestive tract. | The mouth, esophagus, a complex four-compartment stomach, small intestine, and large intestine. |
Rumen | Paunch |
Reticulum | "Honeycomb" |
Omasum | "Manyplies" |
Abomasum | "True Stomach" |
What side is the Rumen on? | The left |
What is the largest of the four compartments? | The rumen |
What is a pouch-like structure in the forward area of the body cavity? | The reticulum |
Heavy and dense feed and metal objects go into which compartment. | The reticulum |
Globe-shaped structure that contain leaves of tissues(like pages in a book) | Omasum |
Hydrochloric acid and digestive enzymes needed for the breakdown of feeds, are secreted here. | Abomasum |
What are tiny projections that increase the surface area and the absorption capacity in the rumen called. | Papillae |
What holds 25 gallons or more of material? | Rumen |
Which compartment is the only one with a glandular lining? | Abomasum |
Tissues are arranged in a network resembling a honeycomb. | Reticulum |
Absorbs water and other substances from the digestive contents. | Omasum |
Which compartment acts as a storage or holding vat for feed? | Rumen |
This compartment is comparable to the stomach of tae non-ruminant | Abomasum |
This compartment is a fermentation vat. | Rumen |
Collectively the reticulum and rumen are called | Ruminoreticulum |
What in the rumen digests or ferments feed | Microbial population |
The rumen absorbs most these that are produced from the fermentation of feedstuffs. | Volatile fatty acid |
Which compartment is the closes to the heart? | Reticulum |
Nails and other sharp objects may work into the tissue of the reticulum and cause this. | Hardware Disease |
How can you prevent or correct Hardware Disease. | By a magnet or surgery |
The small intestine measures about ____ times the length of the animal | 20 |
What is the large area at the junction of the small and large intestine | Cecum |
This is the last segment of the tract through which undigested feedstuff passes | Large intestine |
What are the three sections of the small intestine | The Duodenum, Jejunum, Ileum |
What is the primary digestive activity that occurs in the large intestine? | The absorption of water |
What receives the secretion of the pancreas and the gallbladder, which aid digestion | Small intestine |
Many nutrients are absorbed through _____ into the blood and lymphatic system | Villi (small finger-like projections) |
Large quantities of gas, mostly carbon dioxide and methane are produced in the | rumen |
The rumen is always | Contracting and moving |
As much as 50 to 80 quarts can be produced and added to the rumen a day | Saliva |
Rumination | Cud chewing |
Eructation | Belching |
A cow needs to remove 30 to 50 quarts per hour of the gas to prevent this | Bloating |
Provides liquid for the microbial population, recirculates nitrogen and minerals, and buffers the rumen | Saliva |
A cow may spend as much as 35 to 40 percent doing this a day | Rumination/Cud chewing |
Healthy cows will have how many contractions of the rumen a minute | 1-2 |
Do cow vomit | Rarely |
Volatile fatty acid consist mainly of these three things | Acetic, Propionic, and Butyric acid |
About 30-50 percent of the cellulose and hemicellulose are digested in the ______ by the microbial population | rumen |
What are digested by the rumen microbes and converted into volatile fatty acid | Simple and complex carbohydrates |
Volatile Fatty Acid are absorbed from the rumen into _____ and transported to ______. | Blood stream/ Body tissue |
Volatile Fatty Acid are used as a source of energy for these four things | Maintenance, Growth, Reproduction, and Milk Production |
