Title: New Research on Reproductive Management of Dairy Heifers

Date and Time: September 15, 2020 at 2:00PM CT

Sponsored by: Merck Animal Health

Presenter: Dr. Luís Mendonça

Summary: In this RACE approved webinar, we will highlight findings of recent research studies that focused on improving reproductive efficiency of dairy replacement heifers. Besides discussing the importance of achieving outstanding reproductive performance in dairy heifers, Dr. Luís Mendonça will share how technology can be used to optimize fertility. Recent studies have shown that monitoring technologies can be used to improve efficiency beyond identifying heifers in estrus. Monitoring provides opportunities to further fine-tune reproductive performance by considering timing of AI when using sex-sorted semen and optimizing fertility when using prostaglandin to induce estrus. Furthermore, Dr. Mendonça will discuss the pros and cons of using heat detection or timed AI programs for first service in replacement heifers.
