AbstractThe chemical composition of 10 range plants of dietary importance to cattle and white-tailed deer (Odocoileus virginianus) was determined on the Texas A&I University Range and Wildlife Research Pastures from October 1980-September 1981. Samples were analyzed for crude protein (CP), neutral detergent fiber (NDF), lignin, organic matter (OM), in vitro dry matter digestibility (IVDMD), phosphorus (P), and calcium (Ca) concentration. The grasses were lower (P<.05) in CP and Ca concentration than the non-grasses, while non-grasses had lower (P<.05) NDF content. On the basis of digestibility, fiber content, protein, and mineral concentration, forage quality was highest in the spring. Winter forage samples were of a higher quality than were late summer samples. Low phosphorus concentrations were common throughout the year.
