In this episode of The Maine Farmcast, Dr. Colt Knight and Dr. Glenda Pereira co-host a deep dive into artificial insemination (AI), the original AI that has been revolutionizing livestock genetics for decades. They discuss the inspiration behind UMaine Extension’s new hands-on AI training program, funded by the Mitchell Center and supported by partners including the Maine Beef Producers Association and the National Pork Board. Listeners learn how simulators and practical demonstrations are helping producers master breeding techniques for cattle and swine while tackling real-world challenges like biosecurity, timing, and estrus detection.

The conversation moves from the science of reproductive physiology to the art of precision timing, exploring hormone cycles, synchronization protocols, and the technology driving genetic gain. From dairy net merit values to crossbreeding for hybrid vigor, Knight and Pereira unpack how Maine’s livestock producers can improve herd quality and profitability through smart breeding decisions. They also preview the upcoming Maine Cattlemen’s College (December 6, 2025), where participants can gain firsthand AI experience with UMaine’s simulators and reproductive tract models. Whether you’re a seasoned breeder or just AI curious, this episode brings the classroom and the barnyard together to show how genetics, education, and innovation are shaping Maine’s agricultural future.

If you are interested in attending the Maine Cattlemen’s College Artificial Insemination training, please contact Melissa Babcock, melissa.libby1@maine.edu, to be added to the waitlist or if you are interested in attending future AI workshops. The next in-person workshop after this podcast episode release will be offered on December 6, 2025, in Augusta, Maine.
