I have taken Beef Records. I think it was a good overview of the beef industry, what you would want your future clients to do, and how to help your clients out in the future. The second semester focused more on the cow calf side of the industry. I personally learned a lot and had large animal experience going into school. I know Beef Records and Dairy Informatics are required for some rotations during fourth year, so if you're thinking of doing those you'll want to take both sets of electives. I know for sure Beef Records is a 3 semester series, but only 2 are required for the rotations. I think Dairy is also multiple semesters. They are both easy to do in you're first year so you can leave time for other electives your second and third years.
If you have anymore questions, I'll happy to help out
