Abstract
Goats browsing current season''s blackbrush (Coleogyne ramosissima) twigs consumed diets higher in crude protein, in vitro digestible organic matter, and tannins than did goats browsing older twigs. They also lost less weight than their counterparts browsing older twigs. When given a choice, goats preferred not to eat current season''s twigs, presumably because of their high tannin concentrations and their location within the plant canopy.
