Question 1
Which phase of the beef industry involves purchasing subprimal cuts from a packer and
breaking them down into retail cuts for sale to the public?
A) Stocker phase
B) Feedlot phase
C) Packer/Processor phase
D) Retailer phase
E) Consumer phase
Correct Answer: D) Retailer phase
Rationale: The retailer, such as a grocery store or butcher shop, is the entity that buys large
wholesale (subprimal) cuts and prepares the individual steaks, roasts, and ground beef (retail
cuts) that consumers purchase.
Question 2
What is the primary purpose of lairage in the livestock industry?
A) Growing calves to heavier weights on forage.
B) Finishing cattle to market weight on grain.
C) Holding animals in a resting area before slaughter.
D) Producing breeding stock for the industry.
E) Harvesting and processing finished cattle.
Correct Answer: C) Holding animals in a resting area before slaughter.
Rationale: Lairage is the period of rest for animals after transport and before they are
slaughtered. It allows them to recover from the stress of transport, which can improve meat
quality.
Question 3
If an animal is balking and refusing to move or enter a truck, it is a strong indication of:
A) A genetic disease
,B) A nutritional deficiency
C) Faulty design of the handling facility or truck
D) Dominance behavior
E) Normal animal behavior
Correct Answer: C) Faulty design of the handling facility or truck
Rationale: Well-designed handling facilities work with an animal's natural behaviors. Balking
and refusal to move often indicate a design flaw that is causing the animal stress or fear, such
as shadows, loud noises, or dead ends.
Question 4
The study of the behavior of animals in their natural surroundings is called:
A) Pathology
B) Etiology
C) Ethology
D) Nutrition
E) Genetics
Correct Answer: C) Ethology
Rationale: Ethology is the scientific study of animal behavior, particularly in natural
environments.
Question 5
Equine Hyperkalemic Periodic Paralysis (HYPP) is a genetic disease in horses that causes muscle
contractions due to an excess of what in the blood?
A) Calcium
B) Sodium
C) Glucose
D) Potassium
E) Magnesium
Correct Answer: D) Potassium
Rationale: Hyperkalemic refers to high levels of potassium (K+) in the blood. In horses with
, HYPP, a genetic defect in sodium channels causes potassium to leak out of muscle cells,
leading to episodes of muscle tremors and paralysis.
Question 6
Which of the following animals have a monogastric (simple) stomach?
A) Cows and sheep
B) Horses and rabbits
C) Pigs and poultry
D) Goats and deer
E) All of the above
Correct Answer: C) Pigs and poultry
Rationale: Pigs, poultry, dogs, and humans are all examples of monogastrics, meaning they
have a single-chambered stomach.
Question 7
Cows, sheep, and goats are classified as which type of herbivore?
A) Monogastric
B) Ruminant
C) Hind-gut fermenter
D) Omnivore
E) Carnivore
Correct Answer: B) Ruminant
Rationale: These animals have a four-chambered stomach (rumen, reticulum, omasum,
abomasum) that allows them to digest fibrous plant material through microbial fermentation.
Question 8
Which of the following is NOT one of the six basic classes of nutrients?
A) Water
B) Carbohydrates
C) Fiber
