I am looking to have my 5 year old maiden mare bred this spring. She has already had one heat cycle in early March (in which she only showed for a few days), and I am waiting on the second which if she is cycling normally should fall toward the first of April. My question is when do mares typically settle into normal cycling time frames (4-5 day heat cycles). I live in TN . The spring grass is out and the days are warm. I would like to bred her in April (via AI ) but do not want to spend a fortune on waiting 5-10 days for an ovulation since she will be at the vet for monitoring during the follicle maturation phase of the game.
Any thoughts on how to tell if they are cycling normally if you don't have a teaser? Normally this mare shows to people but that could change when she figures out we're not going assist her. :-)
I plan on taking her to the vet to have her examined next Saturday. He general uses Regumate for 10 days then a prostiglandin shot to bring on heat if she is mid -cycle but if she is still transitional can that heat cycle last for potentially several days and end with out an ovulation?
