In north central South Dakota, barley is more readily available as a feed for swine than is corn. A number of studies have shown that barley either as the only grain or as part of the grain in swine rations supports satisfactory growth. Barley has higher protein content than corn but also greater fiber content. Like all cereal grains, it is considered low in both minerals and vitamins, and supplemental protein is usually recommended. A series of trials using barley as the only grain in rations for growing finishing swine have been conducted at the Experiment Station's North Central Substation, Eureka. General results of these trials have indicated that pigs fed barley in pelleted form gained more rapidly and efficiently than pigs fed the same rations in meal form . Increased gains and feed efficiency, however, were not sufficient to offset the extra cost of pelleting. Trials utilizing low protein rations when the barley tested 11 percent protein or more have suggested a re-evaluation of recommendations with respect to supplementing barley.
