Abstract

The sugarcane is being very used as forrage resource in the feeding of the ruminants in all areas of Brazil, however, few information exist regarding the adaptability of the several available genotypes to the production environment. The purpose of this study was to evaluate 7 sugarcane genotypes aiming the animal feeding in an experiment developed in the Unit of Research and Development of Gália (SP). The 7 treatments were tested on a randomized block design, with three replications. The evaluated attributes were productivity of fresh mass (TMH), productivity of stalks (TCH), productivity of pointers (TPH), proportion of stems (% C), proportion of leaves (% P), index TPH TCH-1, number of stalks for meter (NCM), average height of the stalks (A), medium diameter of the stalks (D), percentage sucrose (PCC), percentage of fiber (F) and index F PCC-1. There were significant differences among the genotypes studied for all attributes. As for the adaptation attributes to the region, ton of fresh mass for hectare (TMH), ton of stalks for hectare (TCH) and number of stalks for meter (NCM), the genotypes IAC86-2480, IAC91-3186, IACSP95-3028 and IAC91-5155 shown superiors to the others. In relation to the attributes that characterize adaptation to the feeding of ruminant, proportion of stalks (% C), proportion of leaves (% P), index TPH TCH-1, percentage sucrose (PCC), fiber percentage (% F) and index F PCC-1 stood out IAC86-2480 and IACSP95-3028. Therefore, two genotypes presented conditions for future evaluations as forrage in the Gália (SP) region.
