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

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