title: The rachitogenic effects of fractions of rye and certain polysaccharides.
abstract: When fed to chicks rye is rachitogenic as well as growth depressing. The component or components of rye that cause these effects have not been identified. In an attempt to separate the factors, a water extract of rye was fractionated by precipitation with ethanol or ammonium sulfate. The precipitated fractions were fed to chicks. Although there were different responses to growth and bone ash from the ethanol fractions, they were not statistically significant. In another experiment, guar gum, pectin, or gum arabic was fed to chicks as 2% of the diet. Guar gum was both growth depressing and rachitogenic, pectin was only growth depressing, and gum arabic was without effect.
