I have 2 mares that have been brought in to be bred to my stallion. Same owner of both mares brought them over not sure where they were on their cycle. One mare is an older maiden, the other has had a few foals by previous owner. I have now had both mares here for 23 days, they have been teased EVERY day they have been here and neither mare is showing any signs of coming into heat. Both mares were cultured clean. Any advise on the best way to bring these mares into heat since they seem to not be cycling. Every other mare we have has been cycling normally so I am not sure what is the best way to go forward on this, thanks for any advise!
You will probably need to have the mares ultrasounded to determine what is going on on the ovaries. Some mares have "silent heats" (follow that link for more details.
The other thing to look at is your teasing method. Some mares require up to 15 minutes of continuous and hard teasing to actually break down and display estrus, so it could be that you are not teasing hard or long enough.
Thanks for the info Jos, I will have the mare owner get them ultrasounded to check their ovaries. There are 5 stallions on the property and one mare is stalled right next to one of the stallions for a good half of the day, so I don't think the teasing is the problem but I will try teasing them for a longer period of time.
