Table 4 shows the effect of treatment, body
condition score and whether cows exhibited estrus at or prior to breeding on AI pregnancy rate. Mean AI pregnancy
rate differences between treatment groups for different locations are shown in Figure 4. The analysis of projected economic outcomes for 100 cows for implementing 5-day CO-Synch protocol instead of 7-day CO-Synch protocol based on the mean AI pregnancy rate difference is presented in Table 5. Three herds would have experienced an economic benefit and nine herds would have had a lesser economic return with the results from this study.
