Just as the title says....how often do mares come in heat??
I think it's different for every mare, but usually like once every 20 days or so?? Lol maybe someone can correct me. My mare usually goes into heat once every 14 days, and she stays in it for about 5 days.
can vary a bit but in general every 20-22 days. Here is a link with a bit more info. http://www.horsekeeping.com/horse_behavior/mare_heat_signs.htm
Horses can have split heats where they come in more often and during the start of the year when they are in transitional they can be longer between cycles.
heat cycles are approximately 21 days They are in heat 3-7 days and then out for 14 days or so
Assuming its spring and we are talking regular heat cycles
Thanks for the replies!
For my mare who I would just love to have spayed, even once a year is too often. She is the definition of moody mare.
(dumb question alert!)
Does anyone know why aren't mares regular all year like humans?
It has to do with the lenght of day light influencing hormon production, and, in fact, in some regions of the world they can go all year round. I better dont try to go into detail, cause I'm sure to mix something up!
I don't know all the details, but it definitely has to do with light. That's why people breeding for early foals often "put the mares under lights". It brings them into estrus faster.
