[QUOTE="cbcr, post: 1136639, member: 16303"] Worked with a customer who had 16 heifers that we sync'd. We used the 30+ day method, left the cidr's in for 16 days pulled them and gave lutalyse on day 30. It seemed that just about all of them were showing some signs of heat when we bred them. Out of the 16 just missed 2 getting all of them bred on timed AI. And one of those heifers could be taken out of the equation because she was only 13 months old. This would calculate out to be an 87.5% conception rate. I have been involved with other cows and heifers using the 7 day method and breeding on observed heats. Seems like the results from that herd with the 7 day method is just about 55-60%. I think that several factors can go into how successful a timed AI program is. Proper nutrition, good herd health program, good minerals and heifers having been in good condition all along can make a big difference. [/QUOTE]
