The objective of this work was to evaluate the use of silvipastural systems as a management option to maintain physiological features of dairy buffaloes and to provide higher levels of thermal comfort. Fifty-six adult females (79±44.12 months; 575±92.90 kg) were evaluated: 30 in an unshaded silvipastural system and 26 in a silvipastural system with 19.9% of shaded area. Heart and respiratory rates, rectal temperature and animal comfort index were evaluated weekly. Means were submitted to analysis of variance, and meteorological and physiological data were correlated by Pearsons method. Shading significantly reduced heart rate and rectal temperature. In 71.4% of the observations, the animals kept in the silvipastural system with shaded area showed thermal comfort index closer to the ideal level. Shading maintains the physiological parameters of dairy buffaloes closer to normal, and improves the animal comfort index. The adoption of silvipastural systems for buffalo production in tropical areas can avoid energy loss due to thermolysis.
