[QUOTE="wbvs58, post: 1600354, member: 16453"] That is about what I would expect. If you were to have done true fixed time AI the numbers would look a lot better. By inseminating those that show heat you have sorted out the tougher ones so you have picked up a few in that group. I can understand how you might want to improve on that group, I like the idea of not inseminating them on the timed AI but to give them 14 days and then PG and inseminate on observed heats. The 7 day protocol is fairly short and you may have some that had been on heat when cidrs went in so did not respond to the PG. Keeping the non responders in for a few more days and observing for heats may also pay dividends. Ken [/QUOTE]
