Dr. Ivan Rush, as you retire, those of us in the Department of Animal Science reflect on your remarkable career. We also wish to say, “Thanks!” Ivan, thanks for 35 years of making us look good. To many of Nebraska’s cattlemen, you are the person who comes to mind when UNL is mentioned. Fortunately for us, your reputation for knowledge is based both on soundly designed experiments and the wisdom of practical experience with cattle. You have earned the respect of cattlemen in Nebraska, in nearby states, and even overseas. Thanks for your contributions to the development of computer programs that calculate rations, for organizing so many Range Beef Cow Symposia, and for guiding the evolution of IRM both in Nebraska and nationally. Mostly, thanks for being so sincerely dedicated to the beef industry in western Nebraska and for always rooting your advice in factual information.
