Abstract
The objective of this experiment was to determine the effectiveness of fixed-time AI utilizing one of two estrus synchronization protocols, CO-Synch or CO-Synch + CIDR, in May-calving cows. Cows synchronized with the CO-Synch + CIDR protocol had increased AI and overall pregnancy rates compared to cows synchronized utilizing the CO-Synch protocol. Due to increased AI pregnancy rates, CO-Synch + CIDR cows calved earlier, resulting in a greater proportion of cows calving within the first 21 days of the calving season compared to CO-Synch cows.
