31

Artificial Insemination
33
What are the three methods of Artificial Insemination?
a. Artificial Vagina b. Electroejaculator c. Manual massage/pressure application
34
It is the manipulation of estrous cycle, using prostaglandins or progestins, so that females in a herd exhibit estrus at approximately the same time.
Estrus Synchronization
35
endogenous naturally occurring fatty acids in the body, one is which has a marked effect on the reproductive system, specifically to regress the corpus luteum (luteolysis) to cause estrus
Prostaglandins
36
commercially available compounds similar to progesterone, which prevents the occurrence of estrus and maintains diestrus period and also pregnancy.
Progestins
37
Increased ovulatory response above the number that would be expected to occur naturally, generated in females by administration of exogenous gonadothropic hormones
Multiple Ovulation (Superovulation)
38
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.
Flushing
39
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.
EmbryoTransplant/Transfer
40
Mechanical division (using microsurgical blade) by micromanipulation of embryo to produce two (twins, or even triplets) genetically identical offspring.
Embryo Splitting
41
its function is for sperm production and storage; male hormone production

63
What are the advantages of Artificial Insemination?
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
64
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. Additional info: Asexual reproduction is not yet know in avian species.
