GUIDE 2025/2026 GRADED A + .
,1. the MOST IMPORTANT protein supplement for livestock feeding in the US (and many other countries) ✓✓
CORRECT ANSWER soybean meal (SBM)
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 ✓✓ CORRECT ANSWER blood meal
3. A protein food derived from slaughterhouse waste, is high in collagen, and is of concern because of "mad cow"
disease? ✓✓ CORRECT ANSWER meat meal
4. what is the most common source of non-protein nitrogen for ruminants? ✓✓ CORRECT ANSWER urea
5. anti-nutritive factor contained in soybeans, and therefore they must be heat- ed to destroy this ✓✓ CORRECT
ANSWER trypsin inhibitor
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. ✓✓ CORRECT ANSWER gossypol
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.-
✓✓ CORRECT ANSWER wheat
8. Which "mycotoxin" is of major concern in peanut meal? (hint ✓✓ CORRECT ANSWER it is a major
concern with corn too) ✓✓ CORRECT ANSWER aflatoxin
9. What are the three major systems of grazing management that we discussed in class? ✓✓ CORRECT ANSWER
continuous grazing
rotational grazing strip grazing
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? ✓✓ CORRECT ANSWER rotational grazing
11. which forage pasture may commonly cause bloat in ruminants? ✓✓ CORRECT ANSWER alfalfa or clovers
, 12. which of the following grasses may contain undesirable levels of prussic acid (cyanogenic glycoside)? ✓✓
CORRECT ANSWER Johnsongrass
13. Warm season grass and is the most extensively produced hay crop in the South? ✓✓ CORRECT ANSWER
Bermuda grass
14. Warm season legume, stemmy and shrubby in appearance, and is important for pasture and hay in SE states ✓✓
CORRECT ANSWER Lespedeza
15. a cool season grass, which is intolerant to heavy grazing pressure and typically low in magnesium? ✓✓
CORRECT ANSWER Timothy grass
16. most widely grown clover in North America; similar to alfalfa but not as productive; may cause produce
salivation (slobbers) in cattle ✓✓ CORRECT ANSWER Red clover
17. major pasture legume in North America, Europe, New Zealand, parts of Australia and South America;
quite resistant grazing pressure. ✓✓ CORRECT ANSWER White clover
18. deep rooted, drought resistant cool season perennial grass infested with endophyte fungus that produce ergot
alkaloids (DW hated mowing her lawn in Georgia because of this grass!) may cause problems in cattle ✓✓
CORRECT ANSWER tall fescue
19. if tall fescue is infected with the fungus, what is the name of the condition that may affect the livestock and
cause necrosis of the hooves, lower limbs, tail, and tips of the ears? ✓✓ CORRECT ANSWER fescue foot
20. if tall fescue is infected with the fungus, which species of livestock is the major one affected with fescue
foot? ✓✓ CORRECT ANSWER cattle
21. cool season grass grown extensively throughout Louisiana as forage crop (for pasture, hay, and baleage)
(widely used for beef and dairy cattle) ✓✓ CORRECT ANSWER ryegrass
22. which legume contains coumarin, which may cause "bleeding disease" in animals that consume it? ✓✓
CORRECT ANSWER yellow sweetclover
