A 72 Percent H2SO4 Method for the Determination of Lignin and Its Use in Animal Nutrition Studies

G. H. Ellis, G. Matrone and L. A. Maynard

Cornell University and U. S. Department of Agriculture1

Abstract

A procedure for the routine determination of lignin in feedstuffs is given

Studies with the cow, sheep, and rabbit indicate that lignin as determined by this method is not digested.

A lignin ratio technique for the determination of the digestibility of feedstuffs is described, and data are presented to show the reliability of this technique.

The use of lignin and of cellulose values in a scheme for the analysis of feedstuffs is discussed in the light of data obtained from digestion trials with animals.
