ANSC 3010 EXAM 2 UPDATED ACTUAL QUESTIONS
AND CORRECT ANSWERS
Question:
1. the MOST IMPORTANT protein supplement for livestock
feeding in the US (and many other countries)
Answer:
soybean meal (SBM)
Question:
2. Protein source collected from the kill floor of slaughter
plants, contains 80+% crude protein, is high in lysine but
severely deficient in isoleucine. It has low digestibility due
to the drying process and therefore is a good source of
rumen undegradable protein to ruminants
Answer:
blood meal
Question:
3. A protein food derived from slaughterhouse waste, is
high in collagen, and is of concern because of "mad cow"
disease?
Answer:
meat meal
Question:
4. what is the most common source of non-protein nitrogen
for ruminants?
Answer:
urea
Question:
5. anti-nutritive factor contained in soybeans, and therefore
they must be heated to destroy this
Answer:
trypsin inhibitor
,Question:
6. Cottonseed meal contains the toxin ____ which is quite
toxic to monogastric animals and may bind to the protein
during the heating process, thus lowering lysine
availability.
Answer:
gossypol
Question:
7. This cool season grass typically ranges from 20 to 30%
protein but grazing must be managed carefully because
of problems with bloat and grass tetany.
Answer:
wheat
Question:
8. Which "mycotoxin" is of major concern in peanut meal?
(hint: it is a major concern with corn too)
Answer:
aflatoxin
Question:
9. What are the three major systems of grazing
management that we discussed in class?
Answer:
continuous grazing
rotational grazing
strip grazing
Question:
10. Of the 3 systems of grazing management (in the question
above), which one results in increased average forage
quality by eliminating over and under grazed patches?
Answer:
rotational grazing
Question:
11. which forage pasture may commonly cause bloat in
ruminants?
Answer:
alfalfa or clovers
, Question:
12. which of the following grasses may contain undesirable
levels of prussic acid (cyanogenic glycoside)?
Answer:
Johnsongrass
Question:
13. Warm season grass and is the most extensively produced
hay crop in the South?
Answer:
Bermuda grass
Question:
14. Warm season legume, stemmy and shrubby in
appearance, and is important for pasture and hay in SE
states
Answer:
Lespedeza
Question:
15. a cool season grass, which is intolerant to heavy grazing
pressure and typically low in magnesium?
Answer:
Timothy grass
Question:
16. most widely grown clover in North America; similar to
alfalfa but not as productive; may cause produce
salivation (slobbers) in cattle
Answer:
Red clover
Question:
17. major pasture legume in North America, Europe, New
Zealand, parts of Australia and South America; quite
resistant grazing pressure.
Answer:
White clover
