1) Which of the following is true regarding ruminant and monogastric digestive tracts?
a. The dental pad of ruminants replaces the lower incisors and canines of the
monogastric.
b. Mechanical (physical) digestion is important in the rumen but this process does not
occur in the simple stomach, monogastric.
c. The forestomach in ruminants is nonsecretory which is different than the secretory
function found in the avian proventriculus.
d. When comparing the stomach and small and large intestine, the stomach makes up the
majority of gastrointestinal tract capacity in both horses and cattle.
e. The acid and digestive enzyme secretions found in the porcine stomach are also found
in the ruminant abomasum and the avian ventriculus.
2) How does the avian digestive system differ from mammalian digestive systems ?
a. While teeth, lips, and tongue are extensively used for food gathering by mammals,
birds can use their beaks and claws for gathering food.
b. There is no difference between the mammalian and avian esophagus as this structure is
used to take ingested food and directly take it to the stomach (ventriculus in birds).
c. The avian ventriculus has similar functions to the ruminant stomach with acid and
enzyme secretion.
d. Cattle use rumination and mixing in the rumen for particle size reduction while birds
use the muscular proventriculus to grind food using ingested grit.
e. The mammalian monogastric stomach can be used to store food while food can not be
stored in any part of the avian gastrointestinal tract.
3) Which of the following best describes the hock joint?
a) Also known as the carpus.
b) Located proximal to the shank in the forelimb.
c) Located on the dorsal surface of farm animals.
d) Located cranial to the flank in pigs.
e) Located proximal to the shank in the hindlimb.
4) Which of the following accurately describes location of body structures?
a) Cranial is the same as posterior.
b) The hook bones would be located on the medial side of the dairy cow.
c) The flank is dorsal to the loin in pigs.
d) The rump is anterior to the shoulder in pigs.
e) The pin bones are caudal to the loin in beef cattle.
5) Which of the following is true regarding the domestication of pigs?
a) Pig temperament has improved by breeding pigs for leanness.
b) The Chinese had a major influence in changing size and conformation of pigs.
c) Hair and skin color is still important currently for identifying breeds with specific growth and
carcass characteristics.
d) Meat quality is a major priority in current breeding programs.
e) The Spanish had a major influence in changing size and conformation of pigs.

6) How are fat depots influential?
a) Seam fat is valued highly by the packer.
b) The hypodermis will provide thermal insulation while kidney fat acts as shock absorber.
c) There needs to be a minimal amount of intermuscular fat over the carcass for beef to grade.
d) As body condition score increases, signs of estrus and percentage pregnant decreases.
e) The amount of intermuscular fat on a carcass is related to beef tenderness.
7) Which of the following is true regarding the respiratory tract?
a) Incoming air can only be warmed by flowing through the turbinate bones.
b) Meatuses are airfilled cavities that communicate with the nasal passages.
c) Conchae in the nasal passages warms, humidifies, and filters air that has entered the nasal
cavity.
d) The epiglottis directly covers the trachea to ensure food does not enter the respiratory system
when an animal swallows.
e) An increase in diameter of structures in the bronchial tree is present as they lead from the
bronchi to the terminal bronchioles.
8) Which of the following is not a function of the respiratory tract?
a) Body temperature regulation.
b) Removing water from the body.
c) Regulation of acid/base balance.
d) Manipulating composition of blood.
e) Gas exchange.
9) Which of the following is true regarding the domestication of cattle?
a) The development of Continental breeds of cattle with their large size has enabled early
finishing with high degrees of marbling in beef production.
b) The cattle that we feed in Canada today are linked to Bos longiforns cattle.
c) Bos primigenius cattle developed a shoulder hump, not much of a dewlap, and droopy ears as
it evolved into today’s Bos indicus cattle.
d) Bos nomadicus was the predecessor of current British and Continental breeds.
e) The European Auroch was the predecessor of current Bos indicus cattle.
10) Which of the following is best associated with all the modifications of the epidermis that we
discussed (integument, hair, hooves, and horns)?
a) Nerves
b) Blood Vessels.
c) Keratin.
d) Corium.
e) Papilla.
