ANSC 4405 final UPDATED ACTUAL
Exam Questions and CORRECT Answers
Optimal response to implants depends on sanitation and proper implanting techniques. Improper
sanitation and technique may cause defects including: - CORRECT ANSWER - crushed
pellets and missing pellets
- improper placement or lost implants
- abscesses
The hormones currently approved for use in beef cattle implants include: - CORRECT
ANSWER - Three naturally occurring hormones (estradiol, progesterone and testosterone).
-Two synthetic hormones (zeranol and trenbolone acetate).
Before any implant is sold, the Food and Drug Administration must approve it to be safe and
effective. There is no such thing as "hormone-free" beef or any other meat, as all meat products
contain hormones. Hormones are produced by all humans and animals for normal body
functioning and maturation. The respective concentration (nanograms/day) of estrogen produced
by pre-pubertal children and the amount found in 3 oz of a steak from an implanted cattle are as
follows (respectively): - CORRECT ANSWER - 40,000 and 1.9
Implant effects on growth curve and carcass characteristics can be described as follows: -
CORRECT ANSWER - Extending the growth curve, in which, more days on feed are
required for animals to achieve similar carcass fat composition of non-implanted steers (14 days
for steers and 7 days for heifers).
Currently approved Synthetic β-Adrenergic Agonists (β-AA) for finishing beef cattle in U.S. are
described as follows - CORRECT ANSWER - Ractopamine and Zilpaterol (not
commercially available)
Steroidal implants and B-agonists function through the same cell membrane receptors.
Therefore, although safe for the animals and consumers, it is not economically attractive to use
both strategies together, since no additional gain in carcass is expected by using such
combination. (t/f) - CORRECT ANSWER - true
, Ractopamine-HCl is a B-agonist FDA approved and on market in U.S. It is commonly fed at
200-300 mg/head-daily for the last 28 to 42 days prior harvesting. A 4-day withdraw period is
required. - CORRECT ANSWER - false
When purchasing a feeder cattle contract, which of the following defines "cattle quality" of the
contract? - CORRECT ANSWER - 700-899 lb steers, medium-large #1 and medium-
large#2
When buying options for live cattle contracts, a premium must be paid. The value of the
premium to be paid for such options depends on the striking price. Which one of the following is
true? - CORRECT ANSWER - -The premium paid for a CALL option decreases as
striking price increases. Because you only take advantage of this future option if cash market is
above striking price (less likely to happen).
-participation on live cattle rising prices ("bull market") = CALL option
-The holder of a CALL option, possesses the right (but not the obligation) to assume a long
position (LONG POSITION = to buy a future contract)
-
The striking price, also known as the exercise price, is the price at which the option holder -the
buyer - may buy or sell the underlying futures contract. (t/f) - CORRECT ANSWER - true
Among the most important variables you must have handy when hedging live cattle future
contracts, there is one considered crucial: - CORRECT ANSWER - BSP
break even selling price
Among the main goals of bunk management, one would highlight: i) avoid digestive upset; and
ii) decrease the feed intake as much as possible to avoid ruminal acidosis. (t/f) - CORRECT
ANSWER - false
Ruminal acidosis can be detected by observation of intake (acidosis decreases feed intake).
However, acidosis can be hidden by pen intakes (multiple animals in the same pen), which tend
to make average consumption to look normal. (t/f) - CORRECT ANSWER - true
