This study aimed to evaluate the behavior of sheep fed babassu cake as a substitution for elephant grass silage. The experiment was conducted at the Federal Rural University of Amazonia (Universidade Federal Rural da Amazônia ‐ UFRA), Brazil, using 45 sheep housed in individual stalls, with unlimited access to feed and distributed in a completely randomized design with five treatments (0, 12.5, 25, 37.5 and 50% inclusion of babassu cake) and nine replications. All of the treatments contained a roughage‐to‐concentrate ratio of 40:60. No differences were observed in the time spent feeding ( P  > 0.05), regardless of the source of roughage used. However, there was a reduction in the time spent in rumination ( P  < 0.05) and an increase in time spent idling ( P  < 0.05) when babassu cake was included in the diet. Although there was a reduction in the time spent chewing the ruminal bolus ( P  < 0.05), the total daily chewing time was the same for all animals ( P  > 0.05). However, the sheep fed babassu cake showed higher feeding and rumination efficiency ( P  < 0.05). Therefore, the substitution of elephant grass silage with babassu cake can be performed at up to 50% without compromising the total time spent eating and chewing, which allows increased feeding and rumination efficiency.
