My first 2 I bred cought first try, March/April foals, I could not take the other 2 mares in until later due to some family stuff. One was breed today, the other keeps having large non productive follicles, so hopefuly she gets something going, if not always next year. Shes coming home June 1st regardless. 

I bred 3 to Guys Easy Jet one to Bugsy Beduino. All are in foal. With this crazy weather it wasn’t easy. I have bred to one horse where they repeatedly sent shipments with NO semen in them. When we complained we told that the shipment had not been handled properly. Everything was our fault. Expensive lesson to learn. Vet was an idiot sucking money out of everyone and the stallion owner was a hot head. Funniest thing—I bought a mare that had been bred to the same stallion and they had the EXACT same problem. Soooooo this year was a breeze. 

Left my mare open on purpose. Almost decided to breed back but I got a keeper filly and decided I didn't need another monster that I got. Going to save pennies and breed to a more expensive stud and maybe even ship from the states to Canada or bring my mare to Montana; haven't decided yet!

We were unable to get my mare in foal.

So here's a question for those that breed frequently, have you heard that some just don't "mix" (I can't figure out how to word this correct so bear with me) as in good straws, great follicle, ovulate how they should...literally everything looking perfect and going how it should, but it just doesn't work an d to try a diff stud next season? I know that the facility did everything they should, we cut no corners, mother nature just hates my plans I guess!

I'm back to the drawing board for next year so if love to hear you guys opinions

 You might have your mare cultured the beginning of next year. I would talk to your vet about it though. 

We did culture, completely clean...no contamination even from being AI'd. I did talk to my vet, the mare was there for an extended amount of time, changing studs was a suggestion from her. I was seeing if anyone had experience with something like this

How old is this mare and is this the first time ever being bred? I didnt read threw all the posts so forgive me if I missed this anywhere..

She's a 12 yr maiden. I know I waited a bit later then I should have 

I had a mare who was bred to BB four seasons. She was clean. After the first shipment in the fifth season didn't work I live covered her with my Special Leader son. Caught first try. She either had a bad reaction to the extender or antibiotic with no fluid showing, or she just wanted some foreplay. 

My mare was covered by the lone drifter son yesterday, so going to wait a few weeks and have her checked. Hopefully she's in foal. She foaled a buckskin colt this year

I was shocked and so happy that my mare took on the first shipment. She had been on Altrenogest for 4 years, had her last dose on 2/19 and then was bred on 5/5. I bred her to No Pressure On Me and I am so excited for this foal. 

He is such an awesome horse. I bred a mare to him also. He runs locally, and I am lucky to watch him run and win.  I believe in this horse, and I think we are smart people for getting in on the ground floor. I bet his babies will be winners!!

Which son of L.D. did you breed to ?  I have a daughter of L.D. She has turned into a wonderful barrel producer. Driftwood himself is still on her papers. 

Well another check this morning and the one we were waiting to find out on is pregnant. Our Embryo Transfer mare ovulated this weekend too and so did the recip, which is actually another mare of ours, about on time. So next weekend we do that transfer assuming there is anything to transfer. Ah definitely ready for the end of this breeding season.

Yes that does happen. There are theories as to why. I'll leave that up to the people who have more education than I do. I just have real world experience. I tried repeatedly to get mares bred before by shipped cooled semen and it wasn't going well.  We were going to try one more time and FedX lost the semen. So I bred her to my JOH son with collected extended semen and she took. We did nothing different except switched from one stallion to another.  

To answer what I think your question is, I do believe that for some reason some stallions and some mares my have trouble with the DNA of the other. Perhaps the mare's system is the wrong PH for the stallion’s semen.  Some mares don't handle the extender well and may have clearance issues.  This is when you need a good repro-vet to track what is happening as you go. That is also the secret to getting older mares to stick. They often have more problems with clearing the inflammation of a foreign protein in their body (semen). Which is why they have a reputation of being harder to settle.  

ETA: If your mare doesn't get in foal this season, I would wait until your absolutely sure she's not in foal, then biopsey her.  You can tell a lot more from a biopsey IMO than you can a culture.
