The production systems of river buffaloes (Bubalus bubalis) are receiving increasing atten- tion in the tropics. The incorporation of trees in pastures (silvopastoral systems) can improve production conditions and animal welfare. The objective of this study was to characterize the behavior of buffaloes in a silvopastoral (SP) system with Leucahena Leucocephala 600 trees per hectare and a system without trees (WT), at the heavy rain (HR) period and the light rain (LR) period in Cuba, in order to assess whether the inclusion of trees in pastures affects buffa- loes thermorregulatory behavior, the following activities were recorded observing 9 animals of 90 kg for 12 days during the daylight period, between 6:00-18:00 hours, at 10 minute intervals: grazing, ingestion from the tree leaves, rumination, water intake, walking, lying, standing, positioned in the shade of trees and wallowing. The sum of positioned in the shade of trees+ wallowing was considered as thermorregulatory behavior (TB) was diferent in both systems and season (P<0.05) represented 3,70 hours in WT and 4,80 hours in SP in the Heavy Rain Period. In the Light Rain Period was SP 0,49 hours and WT showed 2,83 hours dedicated. The wallowing showed differences (P<0.05) in the Heavy Rain Season with 0.62hours in WT and 0,64 hours in the SP. These results describe the behavior the buffaloes and indicate the impor- tance of Silvopastoral systems as a technological alternative of friendly to the animals welfare.
