Does estrus detection increase AI conception rates?

A question remains whether there is opportunity to increase AI conception rates with estrus detection.

By B. T. Tibbitts, T. L. Meyer, D. J. Kelly, and R. N. Funston for UNL Beef Watch Newsletter

This study evaluated how a fixed-time AI (FTAI) protocol versus a modified estrus detection with fixed time AI (MTAI) protocol affected AI and final pregnancy rates.

Reproductive technologies such as estrus synchronization and AI have limited adoption in the beef industry, partially due to added labor. Protocols that limit labor and cattle processing have a greater potential of being adopted.

In the past, pregnancy rates were improved when estrus detection was used. In this study, similar pregnancy rates were achieved without the added labor of estrus detection, likely due to newer protocols that more tightly synchronize estrus.
