A.  aGrazing behavior and activity patterns by free-grazing cattle in the Pantanal region.  c2001  aA study of habitat selection and habitat use free-grazing cattle was conducted in the pantanal, from October 1997 to September 1999. Observations periods lasted 13 hours per day during three days in each month. The location and activity duration of each group of animals was recorded by continuous sampling. Rumination, walking  and resting times were affected (P&lt0,05) by interaction between month and year and grazing time differed (P&lt0,05) only between monts. On average, cows spent 54.9, 29.6, 10.6 and 4.9% of their diurnal hours grazing, ruminant, walking and resting, respectively. The grazing time spent in each landscape unit was influenced (P&lt0,05) by interaction between month and year. The cows exploited more intensively the temporary ponds in 97/98 (26 min ha-1) and the edge of ponds in 98/99 (23.2 min ha-1). Therefore, the adequate grazing management practice may not follow fixed rules for the Pantanal.  abehavior  acattle  aPantanal  aGado  aPastagem Natural  aComportamento  aHabitat selection  aIntake rate  aNatural pasture  aSelecao de habitat  aTaxa de entrada1 aCOSTA, C.1 aCHALITA, L.
