The trend of modern methods of farming requires more time-saving machinery and equipment. This is particularly true of equipment for hog production. There is an ever increasing demand for better and time saving equipment in hog production. It was this demand for new ideas and plans for such equipment that led to the preparation of this circular. Plans in blueprint form are available from the Agricultural Extension Service for equipment shown in this circular when so stated at the end of the description. Please order by number. Most of these same plans will also be found listed in Extension Circular 323 which contains a list of all the plans and printed circulars having to do with building that are available at this time.
