I have a mare who I purchased from down south. At the end of January she started cycling.

Early March I had her shipped north to a much colder climate. Upon her exam when she arrived, she appears to have "shut down" and looks transitional.

My vet has recommended the popular protocol of 10 days Regumate followed by a shot of Lutalyse on day 11.

However, lately it seems, everywhere I read about this topic I am seeing 14 days of Regumate followed by one and sometimes two shots (day 15 & 16) of Lutalyse.

I am wondering, is this the "latest" way to do this?

Can anyone tell me if their vets are suggesting, 10 or 14 days?

Thank you!

I just did 12 days to my mare, who had been transitional for a month, no lutalyse (as she was not cycling yet, she had no corpus luteum), on the 4th day post regumate, she had a 32 follicle, 7th day morning, follicle was 42, gave her a shot of 3000 UI hCG, live cover in the evening, and she is now pregnant !
If you do give lutalmyse (and in your case, you would, as she has been cycling this year), it is on the last day of regumate, or the day before.
she should then be in heat 3-4 days later.

My vet wants 15 days on regumate, day 16 give lutalyse. Tease, tease, tease. Do we order semen when the folical is at 40? Not real sure as my vet was in a hurry when I saw him yesterday. And at what point do you ultra sound? Day 2 of heat? This mare has silent heats. Her mother was a 3 day cycler.

she should start her heat 3 or 4 days after lutalyse, so you would ultra sound on day 5 to see what's happening.
