I have Rob, but unless you use it at the right time of the cycle it does not work right.
I just had my repro vet out and this is what she talked about doing to get my girls going. Although at this time of year she said it would only buy me about 2 weeks but if you are really in a push to get it going then I could try it. This was putting them on Regumate for a couple weeks and getting them going.
I had all my mares ultrasounded to see where I was at and 4 were still in winter mode, (en estrus ?) and 2 were on the verge of going into transition. So in other words she said take a 2 week break and start teasing again. Breed them for 7 days, give them a hcg shot and short cycle them. They probably will not take on the transition heat and if they actually do produce a CL on this heat it will not effect the outcome of it being fertilized.
I am just learning all this and sometimes I get it messed up but I am pretty sure this is what she told me. So in other words, the lutalyse was not going to help me much at this time.
