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
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
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?

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
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.
