AbstractResults of in vitro digestibility trials indicate that big sagebrush (Artemisia tridentata) is a highly digestible browse for wintering mule deer. Subspecies tridentata (62.1% digested dry matter) was more highly digested than subspecies vaseyana (53.2% digested dry matter) and subspecies wyomingensis (51.4% digested dry matter). On an accession level, some accessions of big sagebrush were more highly digested than others. The accessional range was from 44.6% digested dry matter to 64.8%. No relationship was found between total monoterpenoids (essential or volatile oils) content and digestibility.
