How frequently do mares come in heat?

Answer 1

It is advisable to wait until a horse matures before breeding it. Horses are generally finished growing at around four years of age.

If it is a stallion, any age really. Although they are more fertile once mature.

If it is a mare, four is definitely the earliest you should consider. They are finished growing at this time and are capable of carrying a foal to full term without detrimental effects on either mother or baby. If the mare is younger she hasn't finished growing, and the strain of the pregnancy can result in bowed legs and horrible conformation that will make her harder to sell if you ever wish to attempt it. It's like asking a nine or ten-year-old human child to carry a baby.

Answer 2

Same as for full sized horses....usually 5-7 days with most in season by day 10. A few will have a very quiet foal heat (I had one mare that simply did NOT have a foal heat...was penned next to the stallion and even he said she wasn't in season but you could set a clock by her 30 day).

Answer 3

Mares reach puberty by the time they are 2, but they are not normally bred from until they reach the age of 3. they come on heat from early spring at intervalls of about 3 weeks.

Answer 4

A mare's reproductive cycle is usually approximately 21 days.

Answer 5

Most mares cycle every 21-22 days from the first day of one cycle to the first day of the next. Most cycle from mid March to mid to late October in the northern hemisphere temperate zone.

Answer 6

Miniature horse mares cycle at approximately the same rate as any other horse.

An approximately 6 day heat and 14 days of diestrus....for a 20 to 21 day cycle.
