The objective was to evaluate the partial replacement of the pineapple cultural residue silage (SRCAB) by forage palm (0; 29.2; 58.4 and 87.6%), in addition to a control diet with sorghum silage as exclusive roughage, diet for sheep on consumption, apparent digestibility, ingestive behavior. Five crossbred male sheep with an average body weight of 40 kg were used, distributed in a 5 x 5 Latin square, with five animals, five treatments and five experimental periods. The consumption of DM and MO were higher for the levels: 0; 29.2; 58.4; 87.6% substitution in relation to the control diet. Regarding the consumption of CP, at the replacement levels 0, 29.2 and 58.4% it was higher than the control. There was less consumption of NDF for the levels 58.4 and 87.6% in relation to the control diet, for the other levels the consumption was similar. For all substitution levels, the consumption of CNF was higher, compared to the control diet. The consumption of MS, MO, PB, FDN, CNF and NDT decreased linearly due to the replacement of SRCAB by forage palm. The digestibility of DM in relation to the control diet showed to be higher in all levels of substitution by palm, however, in relation to the digestibility of CP only in the substitution levels of 58.4 and 87.6% was higher than the control diet. As for the replacement levels, there was no change in the digestibility of nutrients. The feeding time was similar between all levels of substitution in relation to the control treatment, however the time spent with leisure was longer and the time of rumination less responses were observed, respectively; to the levels of 29.2; 58.4 and 87.6% of inclusion, respectively; due to the replacement of SRCAB by forage palm. SRCAB showed better nutritional value than the silage of the forage sorghum variety BRS Ponta Negra. The inclusion of forage palm to replace the silage of pineapple crop remains is not recommended, mainly because it reduces energy consumption.
