We have an 18 year old mare, 10 foals so far, last one in 2005. She is new to us but she came with her last few years breeding records.
We started her under lights the last week of December 2006. Teasing first week of February, with signs of being receptive on Feb. 4th. Vet came on the Feb.5th. U/S said had a 2 follicle on one ovary and a smaller one on the other ovary (sorry can't rememeber which). She cultured and checked her out, everything returned good. Vet said we were probably in for a long heat cycle (and this is the mares normal history) Hauled our stallion to the clinic for his yearly check up the following day Feb. 6th, he returned home Feb. 9th. Covered mare first time of Feb. 11th and so far every other day since. Called vet 2/20 to let her know this mare is still receptive and standing for the stallion. Made arrangements to pick up an HCG shot to administer on Wednes. 2/12 (6th cover). We covered her again on the 23rd and the 25th, she was still standing and showing signs of being in season last night. Will tease again tonight. My question is... if this is a transitional cycle for her, is there a chance she could actually become bred or am I wasting our time?
With transitional cycles I usually toss them out. We have to book to the various stallions and in Ocala if going to one of the better studs you cana't even double (breed twice in one heat). You had best make sure via your vet you have a large follicle that will ovulate with ovuplant. Each cycle you get one breeding. Breed more than 3 cycles, you have to culture your mare.
