&#x3b2;-(1-6)-Glucanese treatment of glucan from yeast cells, pure or feed grade, especially yeast from the familyand particularly, provides a novel glucan product suitable for use in enhancing the stimulation of host animal immune systems. Solubilization of such yeast cell glucan is further disclosed to extend the usefulness of yeast cell glucan as an adjuvant.

Method or use of a solubilized glucan product to increase immunostimulation in animals

A method of increasing immunostimulation in animals by administering to the animal a glucan product comprising a branched &#x3b2;-(1,3) glucan with &#x3b2;-(1,3)-linked side chains being attached by a &#x3b2;-(1,6)-linkage and being essentially free of side chains containing more than four &#x3b2;-(1,6)-bound glucose units.
