Do a search on here, there are LOTS of threads on showmanship. The first thing to remember is you are not going to win a showmanship class based on how you asked questions, it is first and foremost showmanship so you have to first focus on getting that calf shown. The questions are there to seperate those showman that get in there and are really really close in the way they show. As far as questions it really depends on your age as to what questions you will be asked. But since you are on here asking I will just assume you are a Sr Showman. Things I feel you should absolutely know Breed, Birthdate, Weight, Tag #, Sire, Dam, what are EPD's and what do we use them for, and you should be able to locate some major annatomy traits such as, poll, tail head, switch, brisket, loin, etc, you should also know what type of digestive animals cattle are, how many compartments to stomach and what they are possibly.
I will ask questions from all of those categories, as well as ask you what you like about your calf and what you would change on your calf.
My favorite questions I was ever asked back when I was showing and my favorites to ask when judging are How many teeth does your calf have on top? and How many steers are born in the U.S. every year? You will be surprised how many kids cant answer those questions.
