About 28 days past the initial primary rutting period, mature does that didn't conceive then will hit a second estrus cycle
Normally, the estrus cycle
in rats lasts 4-5 days (16), but in the present study a high level of progesterone concentration in LDE and HDE groups enhanced the duration of estrous cycles due to longer duration of diestrus phase and shorter duration of estrus and proestrus phases in these groups.
Each estrus cycle
is about 21 days long (although it can be 18 to 24 days) and the actual heat lasts anywhere from 18 to 36 hours.
