Botanical Composition of Cattle Diet on Rangelands in the Pantanal Wetland, Brazil

[摘要] - This study aimed to identify the botanical composition of the diet of cattle extensively raised on native grasslands in the Pantanal wetland through the fecal microhystological technique, on a characteristic area of the subregion of Nhecolândia, from October/97 to September/99, and to verify the variation as affected by month, season, year and physiological condition of cows. A set of 726 microhystological slides was prepared, each slide being an observational unit. Based on distribution of maximum occurrence values of each species/slide and in the quantis, the species were classified into four main groups: 1- principal (max >20.0%); 2- medium superior (12.3%
