ALUMINUM IN THE NUTRITION OF THE RAT

Abstract
45 rats (mixed [male][male] and [female][female]) were divided into 3 groups, placed on a constant mineralized milk diet, and supplemented with 0, 10 and 30 [gamma] of aluminum (as Al sulfate) per day. During the 6 wks.'' period from weaning the rats receiving additional Al, with the exception of one group of [female][female] receiving 30[gamma] of aluminum daily, showed a slightly, but really insignificant, better growth (0.3 gram/ day). Reproduction and the estrous cycle were normal in all 3 groups. Analyses of the blood and livers of rats from the 3 groups showed definite absorption and storage of Al. If aluminum is needed in the nutrition of the rat during its most rapid period of growth, one [gamma] per day in the milk will satisfy this requirement.
