title: Carbohydrate utilization by the avian oviduct during the laying cycle.
abstract: In the present work the carbohydrate utilization by the avian oviduct during the egg formation was studied. The pattern obtained for total hexose, fucose, hexosamines, sialic acid, fructose and sulphate demonstrated that in the domestic fowl's oviduct the isthmus and the shell gland secrete the precursors for the protein carbohydrate substance of the mammillae and shell matrix and may contribute during the shell formation with the substrates necessary for the metabolic energy of the organ. The infundibulum only participates as a donor for the metabolic energy.
