Digestible and Metabolizable Energy Content of Varieties of Milo for Rats

Mary Ann May1 and Talmadge S. Nelson

University of Arkansas2 Fayetteville 72701

Abstract

Six varieties of milo were assayed with rats to determine their digestible and metabolizable energy contents. These varieties differed in tannin content and amino acid availability as determined with chicks. Variable digestible and metabolizable energy values were obtained for the different varieties of milo. The correlations between digestible energy and tannin and metabolizable energy and tannin were 0.38 and 0.39 indicating that tannin content had no influence on the utilizable energy content of milo. The increase in the digestible and metabolizable energy content of the varieties of milo tested with the rat were analagous to the biological availability of the amino acids to the chick. The ability of the rat to utilize the energy of milo may be influenced either by factors that affect amino acid availability or amino acid availability itself.
