Soils, and therefore crops, deficient in selenium in the Northeastern United States are well‐known. Brewers grains containing barley grown on high‐selenium western soils should serve as an efficient supplementary source of the element in cattle rations. In this study, beef cattle were fed a diet containing brewers grains for six months and their concentration of selenium in blood was compared to a control group of cattle fed a comparable diet but without brewers grains. The concentration of selenium in the blood of the cattle receiving brewers grains increased significantly (p < 0.01) from an initial level of 12.15 ± 2.74 (average ± standard deviation) micrograms/100 mL to 22.88 ± 3.54 at the end of the feeding period. The control group showed a nonsignificant increase from 15.35 ± 2.29 to 16.19 ± 2.08. There was no significant (p > 0.05) increase in average rate of weight gain between the two treatment groups.
