[QUOTE="GoWyo, post: 1689663, member: 38220"] We used 7&7 heat sync protocol this year on 49 head. The extra trip through the chute was a hassle just because of the pasture rotation situation, but we got it done. Several cows had calved less than 30 days prior to placing CIDRS. Out of 49 head we had 46 show heat and 3 nonresponders. Two of the nonresponders had calved less than 45 days before the breeding date and the other was a 3-year old who calved early March and didn't really have an excuse (she did get bred by the bulll with next heat cycle). We only AI'd the cows showing heats and bred all on observed heat with no timed AI. Four cows did not come into heat until 96 hours after CIDR removal and lutelyze. It was 90*+ the week we AI'd, which was miserable for here, but the heats were strong. Cows were split to 3 different pastures for natural clean up and 2 pastures are over 40 miles from the house, so my observations 18-21 days later were not the best, but I think we are around 70% AI conception, which is typical from past years. I am sure we will lose a few like we always do and they will come back in to heat before August. Our best year was 2019 with 85% bred AI and 2020 was our worst year at about 60%. [/QUOTE]
