Conteúdo: | The diet study was performed for a period of one year, starting in June, 1979. Seasonal cattle diets were determined using the microhistological technique of fecal analysis. Fecal samples were collected on three different allotments of a desert srub range in southeastern. Data from botanical composition of fecal samples were analysed using a two-way analysis of variance procedures to test variability among sampling locations, dates and possible interactions for the Whitehouse and Creosote allotment. A one-way analysis of variance procedures was used to test variability among dates for the Van Gausig allotment. For the WHitehouse allotment, diets varied greatly among sampling locations and dates. Variations among locations was influenced by the differences in vegetative types. The overall diet durint the study period was composed of 56% shrubs, 27% forbs and 9% grasses. There were conssitently more shrubs than forbs and grasses in all seasons except spring. Saltbusch was highest in the diets in September, mesquite in October and pricklypear in January. FIlaree was the most important forb component of the diets which was highly preferred during the spring when it comprised approximately 52% of cattle diets. Annual grasses such as Mediterranean grass and foxtail brome were the majos grass components of diets in spring, and tobosa grass in the summer. Great variation in the diets among locations was observed. In December, for example, saltbush comprised 60% of the diets at the Company Well location, but (...).
