A friend of mine Ai'd a pen of 13 does Tuesday morning at 8:00am. He bred them at 60 hours post CIDR pull. Everything went great and all of the does looked really good.
Thursday afternoon, sometime after 12:00 his farm manager while feeding left the gate open between the pen that the 13 does were in and a pen that had three of his backup bucks in it.
Here is my opinion, within hours these does were either bred or they were not. The frozen/thawed semen only will live for a couple of hours in the doe, unlike fresh semen. That semen either did its job or it didnt on Tuesday.
Here are my concerns, first off how long does the egg live? Assuming that a doe did not take from AI, would they still be able to be bred 110 hours after CIDR removal? I think it is unlikely that they would be bred by the 3 backups this heat period.
The problem I see is the stress the bucks put on the does when they came into the pen causing them to abort. To me that is the biggest risk. What is everyones opinion?
