Solutions
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
