Bovine Flashcards
Ruminant permanent teeth formula
2(I 0/3 C 0/1 P 3/3 M 3/3) = 32
Ruminant deciduous teeth formula
2(DI 0/3 DC 0/1 DP 3/3) = 20
How much saliva does a ruminant produce?
160-180 L
What does their saliva contain? And what do they do?
Sodium bicarbonate and phosphate buffers
Helps neutralize acids normally found in the rumen In order to maiming a healthy ph level
Name the ruminants compartments in order?
1 - reticulum
2 - rumen
3 - omasum
4 - abomasum
Describe the reticulum and what it does
Smallest most cranial compartment
Has a honeycomb appearance to increase absorption surface area
Helps bring feed back up for re-chewing
Traumatic reticulopericarditis is also called?
Hardware disease
Describe the rumen and what it does
A large muscular fermentation vat located on the left side of the abdomen
Stores large amount of food
Mixes feed by strong contraction
Provides an environment for bacteria and Protozoa to grow
What does the rumen produce?
CO2 and methane which is eructated (burped)
vitamin B and K
Volatile fatty acids that are absorbed by the liver and converted into glucose
How do the microbes produce in the rumen help the animal?
They are flushed into the other chambers and are digested and provide them with a major source of protein
Describe the omasum and that it does
Made of many folds that look like leaves
Assists in decreasing particle size and reabsorption of water
Removes bicarbonates to maintain the ph lever of the abomasum
Describe the abomasum and what it does
Considers the true stomach
Secrets digestive enzymes
How does a young ruminate’s digestive track differ from an adults?
Functions like a monogastric animal
Contains an esophageal groove that bypasses the rumen and reticulum for they are underdeveloped
Small intestine is located where and why?
Almost entirely to the right side due to the large rumen
What is unique about the large intestine
It spirals
