Production of sheep and goats in the Brazilian Northeast is important for the livelihood of both subsistence and market-oriented producers. Seasonal nutritional stress on animals in the caatinga vegetational zone of this regions causes periodic high mortality and chronically low productivity. Under such conditions, the survivability of goats has been higher than for other domestic livestock. Possible reasons for this include unique aspects of dietary selection and goat feeding behavior. The objectives of this research were rto seasonally detrmine the botanical and nutritive content of goat and sheep diets, to determine forage intake by grazing goats and sheep, and to copmare t heir feeding behavior. Dietary selections by sheep and goats were similar during the dry season, but diverged markedly during the wer season. Leaf litter from the deciduous treees was the major dietary component for both species during the dry season, and provided t he bulk of dry season forage. Currentt hypotheses predict that goats select dietsd of higher nutritional quality and have a greater forage intake than do sheep. Goats selected diets significantly (p< .05) higher in crude portein, equal (P> .05) in cell wall content, and lower (P< .05) in digestibility than did sheep. Voluntary intake was significantly (P< .05) greater for sheep than for goats. This study did no support such hypotheses. Goats and sheep used feeding stations similarly during the dry season. Feeding staations are grazing sites where animals pause to eat (measured in seconds of duration). However, differences emerged during the wet season. Goats increased (P< .05) their time spen grazing per feeding station as the forage grw in stature and matured, while sheep showed no increase. This study confirmed the vertical stratification of foraging by goats and sheep. Sheep foraged more in lover vertical strata than did goats. Goats spen about 4% of their grazing time in a bipedal stance, while sheep virtually never used a bipedal stance to feed. In addition, no nutritional advantage was found for goats over sheep through use of a bipedal stance. This latter finding is constrained by t he deciduous nature of t he caatinga woodland during the ddry season.
