Q

Increased plasma concentration of which enzymes indicate acute pancreatitis?

A

Amaylase and lipase.

17
Q

What is the main function of the rumen?

A

It helps in mixing the food contents and allows fermentation of fibrous food.

18
Q

Name the organ responsible for bile production.

19
Q

What is milk fever?

A

A problem in high lactating cows after parturition where the cow is deficient in calcium because the onset of lactation draws on the calcium for milk production. This causes muscle spasms.

20
Q

Bile is stored in what organ?

A

The gall bladder.

21
Q

Name the small lymphatic vessels in the intestines that carry the fat to general circulation after absorption.

22
Q

List all the enzymes produced by the pancreas.

A

Amylase, lipase, and trypsin.

23
Q

Why is colostrum important for newborn animals?

A

It provides maternal antibodies.

24
Q

Where does the cellulose digestion occur in horses?

A

In the cecum.

25
Which compartment of a ruminant's stomach is called the true stomach?
The abomasum
26
What is the function of the chief cells in the stomach?
Chief cells produce pepsinogen, that is converted into pepsin, which helps breaking down proteins into peptides.
27
Where is the absorption completed in the simple stomach herbivorous animals like horses?
In the large intestine.
28
What is founder?
A metabolic imbalance in horses that causes painful inflammation of the feet, usually brought on by overeating sweet feed, obesity, or harsh and abrupt changes to the diet.
29
What are the functions of parietal cells in the stomach?
Parietal cells produce hydrochloric acid (HCL) that lowers the pH of the stomach and helps to kill the bacteria ingested with food.
30
What is the function of the rumino-reticular groove in young ruminants?
The groove directs the ingested milk from the esophagus directly into the omasum, bypassing the rumen.
