Four metabolism trials were conducted using swine and hamsters to evaluate the effects of isolated and purified dietary fibers on the utilization of fiber, nitrogen, and minerals. Swine fed a 16% crude protein diet and various types of purified celluloses absorbed less nitrogen than did pigs fed a control diet containing silica flour. No differences in nitrogen metabolism were noted when the crude protein concentration was reduced to 9% although fiber digestion was decreased at the lower protein level. Animal performance, nutrient digestibilities, nitrogen balance, and mineral balance were markedly affected when hamsters were fed silica flour, cellulose, and up to 30% lignin or lignin‐hemicellulose.
