Levantamento sôbre a composição química bromatológica de 39 variedades forrageiras de cana-de-açúcar

Resumen

This paper deals with a survey on chemical compositions of 39 forage sugar cane varieties carried out at the Bromatology Laboratory of the E.S.A. "Luiz de Queiroz" (5th chair). Samples were taken at Sugar Cane Experimental Station "Jose Viziolli", Piracicaba, SP, and the material was analised by standard methods. The main conclusions can be summarised as follows: 1. All varieties showed low protein and mineral contents, but were high in crude fiber and nitrogen free extract fractions. 2. A small, but positive correlation was observed between crude fiber and protein content. 3. The amount of observed variation concerning the various nutrient fractions could be used to select better forage sugar cane varieties.
