ANSC 4405 - Exam 3 UPDATED ACTUAL
Exam Questions and CORRECT Answers
Supplementation - CORRECT ANSWER -
reasons for supplementation based on animals needs and nutrients available during specific
situations throughout the year/places - CORRECT ANSWER - - Correct for nutritional
deficiencies
- Carrier for feed additives (ionophores, antibiotics, bloat preventatives)
- Substitute supplement for forage
- Increasing stocking rate
- Stretch short forage supplies
- enhance cattle management
characterize forage availability throughout the year depending on forage type and season -
CORRECT ANSWER - - warm season for grazing: bermuda grass, bahia, old world
bluestem, forage sorghum, pearl millet.
- cool season: tall fescue, wheat, oats, rye.
explain different needs of supplementation based on type and quantity of grazing material
available - CORRECT ANSWER - - Excess of protein= More energy than protein
- Optimal growth performance= equal amounts of protein and energy.
- Lack of protein: More protein than energy.
Benefits of Ionophores - CORRECT ANSWER - Reduced incidence and severity of bloat.
Describe how to determine needs for supplemental nutrients - CORRECT ANSWER - a)
minerals: always check animal requirements
- impossible for one type of supplement/quantity to be able to supply deficiencies for all
categories throughout the entire year.
, b) Analyze the forage: especially mineral profile. can vary greatly depending on soil fertility and
fertilization. Make your own records.
Feedlot industry overview - CORRECT ANSWER -
Define and exemplify general aspects of beef industry segmentation components. - CORRECT
ANSWER - Seedstock-> cow-calf -> stocker -> finisher -> packer -> purveyor -> retail
Finishing phase - CORRECT ANSWER - - the final grain feeding stage when animals are
readied for market.
- COG, breakeven selling price, live weight, carcass weight priving.
explain potential reasons of current changes in size of feedlots. - CORRECT ANSWER --
feedlot industry - CORRECT ANSWER - Feeding large groups of cattle from 500-1400
lbs on high energy diets to produce high quality beef products
- function as a means of finishing cattle to physiological maturity prior to harvest
-feed high concentrate rations to speed up maturity and improve palatability.
Objective: finish cattle from 600-800 to 1000-1350 lbs.
Quality Grade - CORRECT ANSWER - - marbling and maturity
- Quantity of intramuscular fat in the longissimus muscle (12th and 13th ribs)
-
Yield grade - CORRECT ANSWER - - Measures the proportion of edible or usable meat
after being trimmed of bones or fat.
- Fat thickness: 12th rib
- Rib eye area
- hot carcass weight
