Some Difficulties Involved in the Use of Fecal Nitrogen as a Measure of Dry Matter Intake of Grazing Animals1

R. M. Forbes

Kentucky Agricultural Experiment Station

Abstract

Various factors are discussed, emphasizing the difficulties involved in the use of fecal nitrogen excretion as an index of dry-matter intake of grazing animals. On dried roughages, there is a steady increase in fecal nitrogen excretion per 100 grams of dry matter intake as the protein content of the ration increases. On fresh grass, data are too scanty to warrant definite conclusions beyond the fact that the total fecal nitrogen varies too widely to be of practical use in the manner suggested by Gallup and Briggs.
