Three trials involving 166 growing pigs (initial weight 20.5 pounds) and 96 finishing pigs (initial weight 108.7 pounds) were conducted to investigate effects of feeding high-moisture, acid-treated sorghum to swine. Sorghum harvested at 23% moisture was treated with 1.2% propionic acid. Method of processing (whole or ground) and method of feeding (complete or free-choice) were also evaluated. Pigs fed high-moisture, acid-treated sorghum in a complete ration gained at the same rate and just as efficiently as pigs fed the dry, complete ration. Feeding of supplement free-choice tended to reduce daily gain but not feed efficiency. Finishing pigs fed whole, high-moisture, acid-treated sorghum required significantly (P<.05) more feed per unit of gain than pigs fed the ground high-moisture, acid-treated sorghum. Acid-treated, high-moisture sorghum in a ground complete ration is equal to dry sorghum in feeding value for swine.; Swine Day, Manhattan, KS, November 11, 1976
