Here's a neat quiz I found while looking for an answer to the question I posted earlier. Note, the answers immediately follow the questions, so you will have to get somebody to read the questions to you if you really want to take the quiz! But even if you don't, it is packed with good information ... I printed it off as a handy reference for later. http://www.animal.ufl.edu/Dairy/Dairy Judging/REPRODUCTION.pdf Enjoy!
