Abstract

It was developed at the Instituto de Zootecnia, in Nova Odessa, SP, an experiment to evaluate 60 sugarcane genotypes, with views to the animal feeding. The experiment was in a randomized block design, with 3 repetitions. The dry matter production was similar; however there was wide variation among the data. There were differences among the genotypes for the characteristics: tillage number, tillage weight, nodes, internodes, apex, dead material, neutral detergent fiber, acid detergent fiber, cellulose, hemicelluloses, lignin and non structural carbohydrates. Tendencies of reduction of the percentage of the components of the cellular wall were observed as percentage of nodes and internodes and it increased at percentage of apex and dead material reduced. In relation to the non-structural total carbohydrates percentage the correlations with the fractions of the plant, indicated that those tendencies were opposite. Between the components of the cellular wall and the non-structural carbohydrates percentage the correlation were highly negative. Only 4, among the 60 genotypes didn€™t present the disease Red Rottenness.
