My mare has been covered two seperate cycles we went to the vet yesterday and was told she is still open. Unfortunatley the breeder seems very uneducated--he keeps telling me a mares cycle is 30 days...
anyway the vet said she has 2 large follicles (she should have been in heat while there but does not show unless a stallion is present) but he also said she still had a CL
is that normal???? It had been 20 days since her last cover so she should be comign back in --of course the breeder thinks its too early
the vet also gave her a hormone shot to bring her in so I will be taking her back to the stud tomorrow
I am so frustrated and just want to be done with the stud owner--he more or less treats me liek I am stupid and like my vets no nothing

It's absolutely normal to have either diestrus follicles (in which case a CL would be present and active) or a non-active CL remnant during estrus.

Be aware that if your vet gave her Prostaglandin F in the face of large follicles that ovulation may occur very rapidly (in under 24 hours in some cases) and often with a reduced pregnancy rate.

You might also want to print out this article and give it to the stallion owner...

Does how fast she will ovulate this time depend on how large the follicle was at the time of the shot???--vet said it would be a day or two
but at this point I don't trust anyone

Typically yes. >2 cm expect, ovulation within perhaps 3 days. >3 cm, ovulation possibly within 24 hours.

Read this article. Note that the timing above expands on that in the article.

Thanks Jos... I think once the mare is the bred I may print and send many of the articles to the breeder but he still won't believ ethem I am sure
he told me yesterday that his vet doesn't agree wtih him but he thinks the vet is wrong....

Also wondering is it different in a draft?
Apparently her follicles were 4.8 adn 3.5 on friday--- I took her to the stud on Sunday am and she was in standing heat and he did breed her...so I am hoping we didnt' miss it

I responded on your other thread.

There really isn't any significant difference with draughts.
