Q

Increased ovulatory response above the number that would be expected to occur naturally, generated in females by administration of exogenous gonadothropic hormones

A

Multiple Ovulation (Superovulation)

38
Q

It refers to the practice of elevating nutritional level about 2 weeks prior to breeding for the promotion of ovulation and increase in multiple births among polytoccus animals.

39
Q

It refers to the removal or collection of an embryo in its early stage or development from its own
mother’s (the donor) reproductive tract, and transferring to another female’s (the
recipient) reproductive tract for development to term.

63
Q

What are the advantages of Artificial Insemination?

A
  1. Permits extensive use of outstanding sires for more rapid genetic improvement.
  2. Eliminates/reduces the cost and risk of maintaining sires, especially for small herd
    or flock.
  3. More accurate evaluation of male breeding performance by observing more of its
    offspring.
  4. Eliminates the problem of transporting breeding animals, which are far apart.
  5. Better control of certain reproductive diseases (i.e. sexually transmitted diseases
    and/or venereal diseases)
  6. Eliminates the problem of mating large males with small females, which may cause
    fractures or injuries

Q

True or False.

Female birds do not demonstrate estrous cycle.

True. Whether they are mated or not, they lay their first egg when they reach sexual maturity at about 19-21 weeks of age.
