The entire heat cycle lasts about 20 days. 14 days in diestrus (not in heat) and 6 days in estrus (heat). There are a number of variables that can change this ratio, exposure to a stallion, early embryonic death, infection, hormone imbalance, ovarian and pituitary tumors.
pigs stay in heat for about 21 days then for about 1 month your pig will be back in its heat
During the winter months mares often are not in heat. Once spring comes and days get longer (March to April) Mares will often begin to go into heat. Typically once they start, every 21 days approximately they go into heat. So they are in heat 3 to 7 days, adn then out of heat for about 14 days, then back. In the fall, when days get shorter, they often stop going into heat or it becomes very erratic. That's what I learned from my research! During the winter months mares often are not in heat.

Cats often come into heat every couple of weeks, with a gestation period of around 63 days. A Queen will often come back into heat when the kittens are weaned (around six to eight weeks). So, a female cat can have many, many litters during her lifetime.
Pygmy goats may come into heat about once a month. Their heat cycle may last up to 48 hours, depending on the area that you live in.
Mares are usually in heat (called the Estrus phase) for 3-8 days long, depending on the time of year and whether or not a stallion is present. Early in the year, the mare will normally be in heat for 6 to 8 days but by midsummer only around 4 days.Mares are out of heat for 14-16 days, (called the Diestrus phase) and then return to heat.
Females come into heat every 21 days, plus or minus.
Mares come into heat approximately every 21 days.
The mare should come back into heat (not including foaling heat) 21 days post foaling.
Every 28 days, unless of course she gets pregnant, then it's normally once a year.

Whenever a mare goes into heat. (which occurs most often in spring and summer.)
Every 6 months.
Twice a year.
Since there is no mention of how long the mare has been in continuous heat this is a very difficult question to answer effectively. Generally, mares will enter into heat as early as 3 days post foaling. The length of this heat cycle is variable with many mares ovulating 6 to 10 days post foaling. The number of days post ovulation where the mare acts receptive could make her appear to be in heat for 12 or 14 days post foaling. That being said, mares that do not clean and involute well post foaling will often return to heat early, which may also give the impression that the mare has been in continuous heat.
