The effect of access to artificial shade on respiration rate, performance and behaviour of grazing steers was determined during summer. Forty-two yearling steers were randomly assigned to 3 treatments without replication: (1) no shade, (2) free access to shade, and (3) restricted access to shade. Animals with restricted shade were daily removed from the grazing paddocks and enclosured in a resting area with shade and water between 10.00 and 16.00 h while animals of group 2 had both shade and water available ad-libitum in the grazing area. The respiration rate of control steers (69 breaths/min) was significantly higher than that of shade steers without differences between free and restricted access to shade (58 and 56 breaths/min, respectively). Total grazing time during daylight hours was not affected by shade availability (515 min). Between shaded treatments, animals with restricted access to shade spent significantly (P<0.05) more time grazing during the morning than animals with free access to shade to compensate the lack of grazing between 10.00 and 16.00 h (241 and 168 min, respectively). The amount of time steers with free access to shade spent in the shade structure was strongly related to air temperature (R2=0.85). When air temperature averaged 23.1°C between 06.00 and 20.30 h steers spent on average 50 min in shade; while when temperature averaged 29.6°C steers spent 422 min in shade. No significant difference was found in overall average daily gain among treatments (538 g/a/day). The provision of shade either ad-libitum or restricted reduced respiration rate of steers without affecting diurnal grazing time and animal performance.
