W.  aThe relation of cellulose and lignin content to the nutritive value of animal feeds.  c1938  aData are presented which shown the limitations, as measures of digestibility and nutritive value, of the crude fiber and nitrogen-free extract partition of the carbohydrates in animal feeds. Based on studies of various procedures, methods are proposed for the determina- tion of cellulose and lignin in feeds and feces. The usefulness of the inclusion of these de- terminations in feed analyses is shown by data obtained in digestion trials with rabbits and steers. The data indicate that, at least for Herbivora, a partition of the carbohydrate por- tion of a feed into lignin, cellulose and other carbohydrates may have more biological sig- nificance, and hence be of greater usefulness in predicting feeding values than the pre- sent dicison into crude fiber and nitrogen-free extract.  acellulose  adigestibility  alignin  anutritive value  aAnimal  aCelulose  aDigestibilidade  aLignina  aNutrição Animal  aValor Nutritivo  aAnimal feeds1 aMAYNARD, L.
