Conteúdo: 	A study was conducted on Santa Rita Experimental Range in southern Arizona from July, 1981, to July, 1982, to compare diets selected by Hereford and Barzona cows and study their summer behevioral activities. Diet was determined by microhistological analysis of fecal samples. No praxtical differences in diet between breeds was detected. Grasses dominated the diet except except in winter when grass and shrub consumptio were approximately equal. Forbs were a minor diet component except for short periods in spring. A small number of plant species dominated the diet, despite numerous species being identified as diet components. Grazing behavior was similar for both breeds, being dominated by grazing and ruminating, these constituting around 80% of daily activities.
