ANSC 201 Final Exam-genesis - ANS-to form
-lysis - ANS-to break down
-neogenesis - ANS-new formation
"gateway to the uterus" - ANS--cervix
-open when in heat, closed when pregnant to prevent bacterial invasion
"grades" - ANS--about the same genetically as registered
-not registered, less known about ancestry
# of essential amino acids in:
swine
chicken
ruminants - ANS-10
11-13
0
% protein (as fed) = - ANS-% protein (DM) * (%DM/100)
% protein (as fed)= - ANS-% protein (DM) * (%DM/100)
% protein (DM)= - ANS-(% protein as fed / dry matter %) * 100
% us calorie from animals - ANS-27%
% US protein supply from animals - ANS-64%
% yield= - ANS-clean/grease *100
2 procedures to determine egg quality - ANS-candling, breaking egg open and
observing it
2 types of grades used for beef - ANS-quality (prime,choice...)
yield (1-5)
,3 wool grading systems - ANS-1. american grade-amount of merino breeding
2. spinning count-hacks yarn per pound of wool
3. micron diameter- based on actual fiber measurements
a feed contains 30% moisture. if an animal eats 50 g of this feed "as fed" - ANS-how
much dry matter did it consume,35 g
abomasum - ANS-(true stomach)
-muscular, small interior surface
-HCl & gastric fluids are secreted
absorption - ANS-of everything in SI except water in LI
absorption by monogastric - ANS-movement of materials from digestive tract into blood
stream
-diffusion, osmosis, active transport
absorption by ruminant:
rumen
omasum
SI
LI - ANS-rumen: large amount of VFA
omasum: water, some leftover VFA
SI: amino acids, glucose, vit, minerals, fatty acids, glycerol, some water
LI: water
accessory sex glands (3) - ANS-1. seminal vesicle (2)
2. prostate
3. bulbo-urethral (cowper's) (2)
accessory sex glands functions (3) - ANS-1. secrete nutrients
2. secrete buffers
3. secret substances to cleanse & lubricate urethra
acid curd formation - ANS--isoelectric point, equal # of + and charges combine to
precipitate out caesins (@pH of 4.67)
- soft curd , cottage cheese
acid detergent fiber - ANS--contains cellulose & lignin,
-usually associated with digestibility
,acid whey - ANS--h2o, lactose, minerals, whey proteins (less than sweet whey)
-acid curd formation
acquired wool impurities - ANS-dust, dirt, manure
actin - ANS-thin filaments, light band
active immunity - ANS-acquired by production of antibodies by natural
exposure/recovery or vaccines
actomyosin - ANS--major protein in meat
-largely composed of myosin
ADC = - ANS-[ (Weight of nutrient consumed)-(weight excreted in feces) ] / (weight
consumed)
adrenal corticoids (2) - ANS-from adrenal glands on kidney
-mineral corticoids: regulate concentration of minerals, especially sodium and potassium
-glucocorticoids: help regulate carbohydrate conversions and metabolism
adrenalin - ANS-if mother frightened, vasoconstriction occurs and reduces oxytocin flow
adrenocorticotropic hormone (ACTH) - ANS--from anterior pituitary
-targets adrenal cortex
-tell it to expand
adult - ANS--capacity to produce and release gametes for extended periods
-female: available follicles decrease by atresia
aging methods (4) of meat - ANS-1. 7-14 days, 35F
2. 2-3 days, 60-68F
3. additional proeolytic enzyme- papain
4. wet aging- meat is retained in its own fluid
aging of meat - ANS-done to improve tenderness and flavour
agonistic behaviour - ANS--behaviour activities of fight and flight
-interactions with other animals and humans
, air cell - ANS--b/w outer and inner shell membranes
forms as egg cools, liquids contracts
-supply air to embryo when respiration initiated
albumen functions (3) - ANS-1. insulation
2. shock absorption
3. nutrient source
albumin - ANS--white of egg
-type of protein
allantochorion - ANS-allantois and chorion membranes fuse and attach to uterine lining
allantois - ANS-as yolk sac degenerates, allontois takes on function of absorbing
nutrients
alleles - ANS-different forms of same gene
allelominetic behaviour - ANS--animals of same species tend to do same thing at same
time
-predators benefit the most from this
allometric growth - ANS-faster than rest of body
altricial - ANS-require large amount of parental care after hatching
amnion - ANS--sac that surround fetus, filled with fluid
-protects fetus and absorbs shock
-dosent fuse with anything else
anabolism - ANS-building complex substances from simple precursors (requires energy)
anatomical relationship between epididymis and testicle - ANS-head of epididymis
connects to seminiferous tubules through efferent ductules (very small)
antagonistic hormones - ANS-hormones with equal but opposite effects
anterior/ cranial - ANS-in front of or towards the front
anthelmentics - ANS-drugs given to kill internal parasites
