Almost all of these 500 farmers had raised at one time or another scrubs, grades, and purebreds, and almost to man they joined in a plea for the purebred. Only 1 percent of them reported that they had failed with improved stock. Most replies contained specific estimates showing the superiority of well-bred over-trained-bred animals, and when averaged it was brought out that these men consider that purebreds make about 40 percent better returns on feed used than common stock. It is interesting to note here that another questionnaire sent out by the department a year ago and answered by several hundred farmers showed that in their opinion purebreds have a general utility value a little more than 40 percent greater than common stock. Many use self-feeders. The report prepared by the department on the results of this feeding investigation contains many more interesting sidelights on feeding and corroborates a number of tendencies that good observers must have suspected. For instance, of 400 who answered questions regarding the use of self-feeders, 41.5 percent had used this method of feeding, leaving about three-fifths yet to take up this economy. At present the self-feeder seems to be used mostly in hog raising districts and for poultry. In the Middle West more than half the farmers reporting used it. The general sentiment seems to be that this piece of equipment is especially suited to hogs and chickens, but a few farmers used it for feeding calves and sheep.
