Mammalian Reproductive System Flashcards
Involves normal testicular and ovarian functions through the interplay of primary reproductive organs
Reproductive Physiology
Refers to the gonadotropic hormones that stimulates the production of male sex hormone (testosterone)
Luteinizing Hormone (LH) or Interstitial Cell
gonadotropic hormones for follicle development; production of estrogens; estrus or “heat” in females
Follicle-Stimulating Hormone (FSH)
For ovarian function. this hormone is for ovulation; development of corpus luteum (CL); production of progesterone.
Luteinizing hormone (LH)
period of functional CL and progesterone production (15 days)
Diestrus
ovulation and development of corpus luteum (2 days)
Metestrus
period of sexual receptivity, final follicle maturation (1/2 day)
Estrus
follicular development and estrogen production (3-4 days)
Proestrus
the occurrence of ovarian function in cyclic manner following puberty
Estrous cycle
enlargement, swelling and reddening of the lips of the vulva
Inflamed vulva
bellowing, bleating, grunting
Mating sounds/call
mucous from the vulva/vagina; frequent urination
Discharges
What animal has the sign of reddening and swelling of the vulva during heat cycle?
Cattle, swine, sheep, and goat
The testes of birds are located in […]
inside the body cavity
How do we measure the egg productivity of the live hens on any given day or period?
Number of eggs produced/Number of live hens x 100
= % hen-day production (for 1 day or any period)
How do we measure the egg productivity in relation to the number of hens (housed) at the beginning of the laying period.
Number eggs produced/Number hens housed x 100
= % hen-housed production (for 1 day or any period)
Incubation period of muscovy ducks?
35-37 days
Incubation period of Pigeons
16-18 days
Incubation period of Turkey
28 days
Incubation period of chicken
21 days
Incubation period of mallard ducks
28 days
Incubation period of Parrots/budgerigars
17-31 days
Incubation period of ostrich
42-43 days
Incubation period of geese
28-34 days
Incubation period of guinea fowls
26-28 days
Incubation period of Quails (Coturnix)
17-18 days
Incubation period of Finch
11-14 days
Incubation period of pheasants
23-28 days
Incubation period of swan
21-35 days
Incubation period of emu
50 days
A hormone that initiates parturition from adrenal cortex.
Cortisol
placing or depositing of semen in the female reproductive tract by artificial means rather than by natural mating
Artificial Insemination
What are the three methods of Artificial Insemination?
a. Artificial Vagina
b. Electroejaculator
c. Manual massage/pressure application
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
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
commercially available compounds similar to progesterone, which prevents the occurrence of estrus and maintains diestrus period and also pregnancy.
Progestins
