I would like to hear the protocols of others when treating a cow with a cystic ovary.
Last fall I purchased a couple cow/calf pairs in a partial dispersal from a large well-known Angus breeder. I had an employee of that ranch bid for me. I had selected a number of cows I liked based on videos and data and told him the maximum I was willing to pay. One of the cows he selected turned out to be a former donor cow. She produced one son that was sold to a major stud although he never made it into the line-up after a stifle injury on the way to the stud. I am not sure I would have been willing to bid on her had I known she was flushed for several years. She had a fall heifer on her, but I spring calve, so I left her open all winter which was perhaps a mistake. She was already too fat, in my opinion, when she was delivered and she has not lost weight although she is only on grass.
In May we synchronized her and bred her AI. She was the only cow this year that did not show heat after synchronization. We then put her with a bull for two months from mid-May until mid-July. About three days after we pulled the bull, I saw her in heat for the first time. I've seen her jumping other cows several times since. We preg checked the herd a couple days ago and the vet said she had a cyst. He had other appointments he had to get to, but he said something about giving her a shot and breeding her in a few days when she should be in heat. I thought he said Lutalayse, but I looked on-line and called another guy for advice and the consensus was to give her Cystorelin followed by Lutalayse in 10 days. I gave her the GnRH, but when my Vet called me that evening, he said he had actually popped the cyst and the GnRH was unnecessary.
If this were any other cow, she'd be on the truck with the other opens, but I hate to give up. I would really like at least one more calf. Her heifer did not settle either, but I knew that was a possibility since she just turned one. I'm considering one more try AI even though that means another fall calf.
