Thanks Ivan

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.

Ivan, time and again you have put extra effort into helping students. One of our graduate students summed it up, “We were always prepared before giving seminars at Beef Committee Meetings because Ivan would be there. He would be the most critical, but it was wonderful because he would also be the most interested in our research.” Ivan, you put those data to use on countless operations across the state.

Sometimes you forced us to explain their value to producers. Sometimes you showed us how our approach needed to change so our data could be valuable to producers. Sometimes you needed to educate those of us on the faculty. For all of this, thanks. Although you may be unaware, your actions and your comments have inspired some “legends.” No doubt, you will thus continue to push us in service to the industry for the foreseeable future. For all of these and others unmentioned, Dr. Ivan Rush, the department is indeed grateful. Thank you.
