Abstract

From the laboratories of Physiological Chemistry and Animal Husbandry, Iowa State College, Ames. Manganese in small amounts stimulated the growth of rats. The basal diet employed consisted of casein 18, years 12, cod liver oil 5, salts 185, 3.7, and dextrin 61.3. Manganese sulphate was fed at two levels, 100 and 600 parts per million of ration. In 56 days the control gained 1.78 grams daily and consumed 434 grams of feed per 100 of grain. On the smaller manganese allowance the gain was 2.06 grams, and the feed requirement was 391.4 grams for 100 gain. On the larger manganese allowance the figures were 1.69 and 458.5. Apparently the 600 parts of manganese sulphate per million inhibited growth.
