A producer notices that lightweight heifers purchased in the spring tend to be
heavily discounted compared to heavier heifers, but later in the fall their selling
price is relatively stable. What is the best explanation for this observation?
a) Heifers have lower feed efficiency than steers
b) Heifers have fewer market options compared to steers
c) Heifer prices decline less as weight increases and have alternative market
potential
d) Heifers gain weight slower than steers
Correct Answer: c)
Rationale: Heifers often experience less price decline as weight increases
compared to steers. Additionally, they can enter alternative markets such as
reproduction or embryo transfer programs, which supports their value stability.
Lightweight heifers are discounted more initially, but heavier heifers retain value
better over time.
A group of calves were heavily supplemented during preconditioning. When
turned out on wheat pasture, their gains were lower than expected. What is the
most likely reason?
a) Reduced forage intake due to satiety
b) Decreased compensatory growth response

c) Increased parasite load
d) Poor forage digestibility
Correct Answer: b)
Rationale: Supplemented calves during preconditioning often experience reduced
compensatory gain during backgrounding. Their bodies have already begun
shifting toward fat deposition rather than rapid lean gain, limiting the expected
ADG increase when moved to high-quality forage like wheat pasture.
A producer evaluates a Value of Gain (VOG) table and observes negative values
across several weight classes. What does this indicate?
a) Feed costs are too low
b) Market price is increasing rapidly
c) Profitability is guaranteed
d) No adjustment in cost of gain can ensure profit
Correct Answer: d)
Rationale: Negative VOG values indicate that even if cost of gain (COG) is reduced,
profitability cannot be achieved under current market conditions. It signals an
unfavorable economic scenario for adding weight to cattle.
A rancher allows cattle to graze forage sorghum immediately after a frost event.
Several animals show signs of poisoning. What is the likely cause?
a) Excess nitrate accumulation
b) High cyanogenic glycosides producing toxic compounds
c) Excess fiber intake
d) Low protein availability

Correct Answer: b)
Rationale: Frost or tissue damage increases cyanogenic glycoside levels in forage
sorghum. These compounds release hydrogen cyanide when consumed, leading to
toxicity. Proper management includes avoiding grazing after frost or allowing time
before grazing.
A student is asked to determine the correct stage to terminate grazing on dual-
purpose wheat. Which method should they use?
a) Measure plant height weekly
b) Count number of tillers
c) Assess crude protein levels
d) Identify the First Hollow Stem (FHS) stage
Correct Answer: d)
Rationale: The First Hollow Stem (FHS) stage signals the transition from vegetative
to reproductive growth. Continuing grazing beyond this stage can reduce grain
yield, so it is a key decision point for removing cattle.
A manager is planning optimal grazing timing for a pasture. Which factor
combination should be prioritized?
a) Soil type and rainfall
b) Animal genetics and breed
c) Forage quality and forage quantity
d) Market price and cattle weight
Correct Answer: c)

Rationale: Optimal grazing depends on balancing both forage quality and
availability. High-quality forage with insufficient quantity or vice versa limits
animal performance, so both must be considered together.
A producer claims that the High Plains and Rolling Plains in Texas have similar
landscapes due to being geographically close. How should you respond?
a) Agree because rainfall is similar
b) Agree because soil composition is identical
c) Disagree because they are separated by the Caprock and differ significantly
d) Disagree because both regions receive no rainfall
Correct Answer: c)
Rationale: The Caprock separates these regions, leading to major differences in
rainfall and landscape. The High Plains are drier, while the Rolling Plains receive
significantly more precipitation.
A nutritionist recommends adding monensin to steers grazing wheat pasture.
What is the expected benefit?
a) Increase water intake
b) Prevent bloat and improve feed efficiency
c) Increase fat deposition
d) Reduce grazing time
Correct Answer: b)
Rationale: Monensin is an ionophore that improves feed efficiency and helps
reduce bloat risk in cattle grazing lush forages like wheat pasture.
