ANSWERS | VERIFIED ANSWERS GRADED A+ | LATEST EXAM
UPDATE
reproductive efficiency - CORRECT ANSWER - # live offspring born in a
period of time
importance of repro efficiency - CORRECT ANSWER - more born --> more
to sell-->stability of operation
repro efficiency effect on maintenance cost/unit - CORRECT ANSWER -
more babies--> lower cost/unit
repro efficiency effect on selection process - CORRECT ANSWER - more
babies--> greater oppurtunity for genetic improvement
species differences - CORRECT ANSWER - know what environment,
management, and goal is best for each animal
physiology influence on repro efficiency - CORRECT ANSWER - does
animal have physical ability to reproduce
genetic potential influence on repro efficiency - CORRECT ANSWER - does
animal have gene for multiples
nutrition influence on repro efficiency - CORRECT ANSWER - too fat or too
thin
,season influence on repro efficiency - CORRECT ANSWER - spring long
days = best to repro
other factors influence on repro efficiency - CORRECT ANSWER -
heat+humidity not good for repro
Testes - CORRECT ANSWER - primary sex organ in males
Gamete (sperm) function - CORRECT ANSWER - in testicle, sperm is
produced by seminiferous tubules
endocrine function - CORRECT ANSWER - within testicle, testosterone is
produced by interstitial cells
epididymis - CORRECT ANSWER - long tube attached to side of testicle -
functions as area for sperm maturation and storage - sperm must be mature
before active
Vas Deferens - CORRECT ANSWER - tube that transports sperm from
epididymis to urethra
Ampulla - CORRECT ANSWER - a reservoir in animals that ejaculate rapidly
(bulls, stallions, ram, and buck)
- found where urethra meets vas deferens
- temporary storage depot for sperm
prostate gland - CORRECT ANSWER - nourish and stimulate activity of
sperm
-opens into urethra close to opening to bladder
, vesicular gland (seminal vesicles) - CORRECT ANSWER - neutralize urine
residues and stimulate activity of sperm
bulbourethral glands (cowpers glands) - CORRECT ANSWER - neutralize
urine residues, add volume to ejaculate, form gel in boar semen that plugs
cervix in sow
-opens into urethra
urethra - CORRECT ANSWER - large muscular canal from bladder through
full length of penis for sperm and urine
penis - CORRECT ANSWER - passageway for sperm and urine
glans penis - CORRECT ANSWER - free end of the penis
fibroelastic cavernosum tissue
sigmoid flexor - CORRECT ANSWER - when s curve streightens to make
erection
- in bulls, boar, ram
cavernosum tissue - CORRECT ANSWER - spongy tissue that fills with blood
making the penis rigid and erect in preparation for mating
vascular cavernosum tissue
no sigmoid flexor - CORRECT ANSWER - stallion, dog
retractor muscle - CORRECT ANSWER - bends urethra when not erect
boar shape - CORRECT ANSWER - curved to fit in cervix
