This document discusses posture and pasture lands. It defines posture as land used for grazing by domesticated livestock such as cattle, horses, sheep, or swine. Pasture lands are enclosed tracts of farmland grazed by livestock. The vegetation in pastures consists mainly of grasses and legumes. Pasture lands are distinguished from rangelands by being more intensively managed through practices like seeding, irrigation, and fertilizer use. Factors like soil type, temperature, and rainfall impact pasture management. Unless undergoing factory farming, pasture is the main food source for ruminants grazing livestock.
