ANSC 1401 EXAM 3 Test Questions With
100% Actual Detailed Answers 2026-2027
Updated.
concentrates - Answer high in energy, low in fiber, highly digestible (grains: corn, wheat)
carbonaceous - Answer concentrates:
low in protein, cereal grains, molasses, corn, wheat, oats
nitrogenous - Answer concentrates:
high in protein; such as tankage, dairy products (soybean meal, cottonseed meal)
roughages - Answer low in energy, high in fiber, less digestible; grasses, hays
carbonaceous - Answer roughages:
low in protein; mature grass hay, stover, mature grain silage
nitrogenous - Answer roughages:
high in protein; legume hay and silage, growing pasture and silage
water - Answer what is the cheapest and most abundant nutrient?
T - Answer T/F:
an animal will die more quickly from lack of water than from lack of any other nutrient
10-14% - Answer death occurs after how much loss of water in the body?
drinking, ingested (contained in/on feed), metabolic (breakdown of nutrients) - Answer what
are the sources of the nutrient of water?
function of water - Answer 1. transport of nutrients and excretions
2. in chemical reactions and as solvent properties
3. body temperature regulation (body temp fluctuates w/o causing distress; may fall to 93°F at
night, rise 105°F in daytime; sweat)
4. maintenance of shape of body cells
, 5. lubrication and cushioning
T - Answer T/F:
water quality is just as important as water availability
proteins - Answer nutrients composed of amino acids (22)
amino acids - Answer building blocks of proteins
amino acids→peptide→polypeptide→protein - Answer what is the structure of proteins?
protein analysis - Answer determine N content and multiply by 6.25 (100/16% N in protein)
nonprotein nitrogen (NPN) - Answer a substance that contains nitrogen that is not apart of
amino acids; urea, biuret
urea - Answer H₂N-C-NH₂; much cheaper source of protein
proteins - Answer what does bacteria need to function?
function of proteins - Answer 1. basic structural unit of animal body
2. body metabolism: enzymes, hormones, immune antibodies, hereditary transmission
structures are composed of proteins
3. energy source: excess will be excreted or stored as fat/muscle
hormones - Answer what causes growth?
carbohydrates (CHO) - Answer main source of energy for our bodies
photosynthesis - Answer produces CHO's: 6CO₂ + 6H₂O + 673 (calories of radiant energy from
sunlight) Chlorophyll: C₆H₁₂O₆ + 6CO₂
monosaccharides - Answer (C₆H₁₂O₆) simple sugars/one sugar molecule; glucose, fructose,
galactose
disaccharides - Answer (C₆H₂₂O₁₁) two sugar molecules
