This study was designed to assess nutritional benefits and/or toxicosis of ingestion of pre-bloom tarbush leaves by sheep fed a low quality native grass diet Sixteen ruminally cannulated sheep (46 kg) housed in individual pens were randomly assigned to 1 of 4 treatments for 28 days. Treatments were ground tobosa grass \textit{(Pleuraphis mutica }Buckl.) substituted with 0,10, 20, or 30\% (dry matter basis) whole tarbush leaves (19\% CP). At 20 and 30\% of the diet, tarbush increased (P = 0$^{\textrm{.}}$0049) dry matter intake during week 3, and sheep consuming 30\% tarbush tended to increase dry matter intake during week 2 (P = 0$^{\textrm{.}}$0559). Dietary tarbush did not affect any variable associated with ruminal fluid kinetics, particulate digesta kinetics, or in situ degradation rates of tobosa dry matter or neutral detergent fiber (P{\textgreater}$^{\textrm{.}}$05). Molar butyrate proportions \textit{(P }- 0$^{\textrm{.}}$0032) and total volatile fatty acid concentrations \textit{(P = }$^{\textrm{.}}$0064) were greater for the 30\% tarbush treatments. Ruminal ammonia was greater (P{\textless}$^{\textrm{.}}$0029) at 6,8, and 12 hours postfeeding for the 30\% tarbrush treatment. Sheep lost body weight regardless of treatment; however, sheep not fed tarbush tended (P = 0$^{\textrm{.}}$0945) to lose more weight Serum clinical profiles (day 0,7,15, and 21) confirmed nutritional stress but did not suggest toxicosis.},
