N2 - The objective of this study was to evaluate the daily intake and total apparent digestibility of dry matter, organic matter, crude protein, gross energy, ether extract, neutral detergent fiber, acid detergent fiber, total and non-fibrouscarbohydrates, total digestible nutrients, energy intake and nitrogen balance of silages of six maize varieties with early orsuper early cycles recommended to Northeast Brazil. Twenty-four male castrated lambs were lodged in metabolic cages.A completely randomized design with six treatments and four replications was used, with means compared by Tukey test at5%. There were no differences among varieties for any of the evaluated variables regarding intake and apparent digestibility. Concerning the intake of digestible energy, metabolizable energy and the ratio content of digestible and metabolizableenergy, significant differences were observed between varieties and BRS Assum Preto showed highest values of metabolizableenergy (2.650,8 kcal/day). All of the treatments presented positive nitrogen balance and did not differ among themselves. The varieties asessed can be an additional option to the semiarid regions in Brazil.
