ANSC 1401 EXAM 3 Questions with Complete
Solutions
concentrates Correct Answer-high in energy, low in fiber, highly
digestible (grains: corn, wheat)
carbonaceous Correct Answer-concentrates:
low in protein, cereal grains, molasses, corn, wheat, oats
nitrogenous Correct Answer-concentrates:
high in protein; such as tankage, dairy products (soybean meal,
cottonseed meal)
roughages Correct Answer-low in energy, high in fiber, less digestible;
grasses, hays
carbonaceous Correct Answer-roughages:
low in protein; mature grass hay, stover, mature grain silage
nitrogenous Correct Answer-roughages:
high in protein; legume hay and silage, growing pasture and silage
water Correct Answer-what is the cheapest and most abundant nutrient?
T Correct Answer-T/F:
,an animal will die more quickly from lack of water than from lack of
any other nutrient
10-14% Correct Answer-death occurs after how much loss of water in
the body?
drinking, ingested (contained in/on feed), metabolic (breakdown of
nutrients) Correct Answer-what are the sources of the nutrient of water?
function of water Correct 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 Correct Answer-T/F:
water quality is just as important as water availability
proteins Correct Answer-nutrients composed of amino acids (22)
amino acids Correct Answer-building blocks of proteins
, amino acids→peptide→polypeptide→protein Correct Answer-what is
the structure of proteins?
protein analysis Correct Answer-determine N content and multiply by
6.25 (100/16% N in protein)
nonprotein nitrogen (NPN) Correct Answer-a substance that contains
nitrogen that is not apart of amino acids; urea, biuret
urea Correct Answer-H₂N-C-NH₂; much cheaper source of protein
proteins Correct Answer-what does bacteria need to function?
function of proteins Correct 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 Correct Answer-what causes growth?
carbohydrates (CHO) Correct Answer-main source of energy for our
bodies
