Notes:
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.
