Like cow,an says focus on the fact it works to improve the herd through use of superior genetics.... Maybe not focus on what it does for show cattle, but feed efficiency calving ease in beef cows, and increased production in dairy...making more with less..... Also that it allows people to efficiently have smaller herds on acreages etc. point out that while many use good old fashion heat detection with no hormones that hormones can be used and explain how it works, it is a science project after all..... These practices again are used to improve efficiency, Would not have a tech come to ai one cow if they lived very far..... Illustrate the anatomy with a visual aid.... Could go so far and have some volunteers try to put a hot dog on a ai instrument, or even a kabob stick. While blind folded with a couple towels around the hotdog to demonstrate how much skill is involved......
