ANSC 1401 FINAL EXAM CERTIFICATION
EVALUATION TEST PAPER 2026 COMPLETE
STUDY QUESTIONS WITH CORRECT ANSWERS
◉ importance of repro efficiency. Answer: more born --> more to
sell-->stability of operation
◉ repro efficiency effect on maintenance cost/unit. Answer: more
babies--> lower cost/unit
◉ repro efficiency effect on selection process. Answer: more babies--
> greater oppurtunity for genetic improvement
◉ species differences. Answer: know what environment,
management, and goal is best for each animal
◉ physiology influence on repro efficiency. Answer: does animal
have physical ability to reproduce
◉ genetic potential influence on repro efficiency. Answer: does
animal have gene for multiples
◉ nutrition influence on repro efficiency. Answer: too fat or too thin
,◉ season influence on repro efficiency. Answer: spring long days =
best to repro
◉ other factors influence on repro efficiency. Answer:
heat+humidity not good for repro
◉ Testes. Answer: primary sex organ in males
◉ Gamete (sperm) function. Answer: in testicle, sperm is produced
by seminiferous tubules
◉ endocrine function. Answer: within testicle, testosterone is
produced by interstitial cells
◉ epididymis. Answer: long tube attached to side of testicle -
functions as area for sperm maturation and storage - sperm must be
mature before active
◉ Vas Deferens. Answer: tube that transports sperm from
epididymis to urethra
◉ Ampulla. 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. Answer: nourish and stimulate activity of sperm
-opens into urethra close to opening to bladder
◉ vesicular gland (seminal vesicles). Answer: neutralize urine
residues and stimulate activity of sperm
◉ bulbourethral glands (cowpers glands). Answer: neutralize urine
residues, add volume to ejaculate, form gel in boar semen that plugs
cervix in sow
-opens into urethra
◉ urethra. Answer: large muscular canal from bladder through full
length of penis for sperm and urine
◉ penis. Answer: passageway for sperm and urine
◉ glans penis. Answer: free end of the penis
◉ fibroelastic cavernosum tissue
sigmoid flexor. Answer: when s curve streightens to make erection
, - in bulls, boar, ram
◉ cavernosum tissue. Answer: spongy tissue that fills with blood
making the penis rigid and erect in preparation for mating
◉ vascular cavernosum tissue
no sigmoid flexor. Answer: stallion, dog
◉ retractor muscle. Answer: bends urethra when not erect
◉ boar shape. Answer: curved to fit in cervix
◉ ram shape. Answer: has extention of urethra
◉ scrotum. Answer: contains and protects testicle as well as
regulates temperature
◉ cremaster muscle. Answer: regulates temperature
◉ castration effects. Answer: no secondary sex characteristics
grow slower
fatten quickly
