The objective of this paper was to evaluate the foraging strategy adopted by cattle on grazing and to determine the relationship between patch biotic features and grazing time, from October 1997 to September 1999, in an area in the Nhecolandia sub-region, Pantanal, Brazil. All observations were made in an area of 151 ha, under continuous grazing and light stocking conditions, so that the cows had the opportunity to be selective in their grazing. The grazing time (min/ha) in each patch was verified by continuous sampling. In the area, spatial scales were identified based on functional use by cattle: nine feeding stations, nine landscape units and 29 feeding sites. Based on foraging hierarchy theory, the foraging decisions at spatial scales presented the following order: feeding station, landscape unit, feeding site, patch, species, plant part and bite. The main grazing patches represented 25% of the total area. With no constraints caused by abiotic factors, cows spent more time on the patches that allowed maximization of the intake, obtained through the presence of a greater number of 'preferred' species. These species provided greater levels of crude protein and lower levels of neutral detergent fiber. However, not all patches selected for grazing presented a greater quantity of dry matter. Intake rate also appeared to be maximized by increasing the daily grazing time. The animals used spatial memory and social learning to choose the patches for grazing. Thus, the foraging decisions can be explained by deterministic and analytic theories, complementary to each other.
