Comparative Nutritive Value of Glacier and High Amylose Glacier Barleys^{1 ,2 ,3,}

Montana State University, Bozeman 59717

Abstract

Five pairs of High Amylose Glacier and Glacier barleys were compared chemically and with weanling rats in growth and nitrogen balance trials. High Amylose Glacier contained more (P<.01) amylose and less (P<.01) amylopectin than Glacier. Osborne fractionation of the protein from the two cultivars revealed major protein differences resulting in different amino acid compositions. High Amylose Glacier contained more (P<.05) of the salt soluble proteins, more (P<.01) lysine and produced superior (P<.01) growth and protein efficiency ratios in weanling rats. The biological value (BV) of High Amylose Glacier was greater (P<.01) than that of Glacier although true protein digestibility (TPD) was highest (P<.01) in the latter barley. The reversal in values obtained in BV and TPD for these cultivars may be explained by their respective differences in protein composition.
