Patterns of environmental use by cattle and consumption of supplemental food blocks
The present study was conducted to evaluate if cattle supplemental block consumption was associated with the spatial pattern of environmental use.

The present study was conducted to evaluate if cattle supplemental block consumption was associated with the spatial pattern of environmental use. In Phase I the environmental factors which affected these patterns of usage were studied. Cattle distribution was estimated using an indirect method based on the distribution of scats accumulated from 1 October 1986 to 26 October 1986.

Blocks were assigned to shelter, water and meadow areas. and the weight of each block as well as the number of scats around each block were determined at the beginning and at the end of the study (2 February 1987 to 4 April 1987). Although the meadow area had presented the least use (per sample unit) at the beginning of the trial, block consumption was significantly greater in this area, indicating that hypothesis (3) best predicts block consumption. In Phase III we tried to replicate the previous results on a larger scale. A 3100-ha field with 1097 animals was used from 10 June 1987 to 10 October 1987. Three types of area were determined with respect to the distance to the watering place. A similar tendency as in previous phases was obtained. Blocks located near the watering place were less consumed than those in an adjacent foraging area. The overall results suggest that placement of supplemental blocks near watering sites will not lead to optimum utilization and should not be recommended. © 1992 Elsevier Science Publishers B.V.
