Effects of Storage Upon the Nutritive Value of Barley Grain as a Source of Protein

Under the conditions of these studies the nutritive value of barley protein was not decreased when the grain was stored for as long as three years. No significant differences were noted in the nitrogen retention or the weight gain of growing rats fed stored or fresh barley either as the only source of protein or as a partial source of protein. In the case of growing-fattening swine, the average weight gains and feed efficiency values obtained from feeding barley which had been stored for three years were equal to those obtained with new-crop barley when both barleys were supplemented with equal amounts of casein or equal amounts of a soybean-cottonseed meal mixture.
