Excerpt from Rfd Letter to Radio Farm Directors: From Radio and Television Service; April 1, 1955

Jules Renaud announces that this week's TV package from.the Department is about those now famous identical twin - calves and what they have shown farmers and ranchers about feeding calves carried several months on sparse winter forage or drought-stricken range. Identical twin-calves are no ordinary twins they look alike, act alike, feed alike, and are alike because they developed from the same egg. Their use in research is just the scientist's gimmick to get quick results at lower cost. By using one of the twins as a control, they can get a more accurate test of the feeding of the other than if they used quite a number of ordinary animals for the test. The 20 frames of slide film Jules is sending out this week show how to feed calves so they make a come-back after being a long time on short rations, if they get enough protein, carotene, and minerals. This twin-calf research is continuing to find out just how little protein supplement is enough.
