puberty
Start of Cycles = Reproductive maturation
Parturition
expulsion of fetus/placenta at end of pregnancy/gestation
Estrous Cycles
ovulation of cycles) female mammalian species
proestrus
growth of follicles/regression of old CL
estrus
estrogen = heat
metestrus
CL formation
diestrus
max CL function, embryo implantation, establishment of pregnancy
seasonal breeders
seasonal estrus cycles, daylight length controls season of breeding
short day breeders
fall/winter (sheep/goats)
long day breeders
spring/summer
gestation
growth and development of offspring in the uterus
dystocia
problem during birth
stages of parturition
predatory stage (fetus rotates itself into position required Cervix begins to dilate) Expulsion stage: (uterus begins to contract more frequently and with increased force. Fetus is expelled from body of female at this stage through the birth canal (cervix+vagin)). Cleaning stage: (at this stage the placenta (“afterbirth”) is expelled from the body)
