AbstractWe tested the effect of feeding one-seed juniper on total intake, VFA profile, and plasma amino acids (AA) of 12 does and 12 ewes fed sudangrass and a basal diet with no protein supplement (Control; 5% CP) or rumen degradable (SBM; RDP 15% CP) or undegradable (FM; RUP 15% CP) protein supplement. After 15 d of adaptation to sudangrass and basal diets (period 1), animals received one-seed juniper leaves in addition to sudangrass and basal diets during a second 15-d period. Each food was fed separately during 3-h periods at 10% of previous day intake. Blood and ruminal fluid samples were collected on the last 2 d of each period to determine plasma AA, VFA (µM), and rumen pH. Analyses followed a split-plot design with periods with or without juniper as a sub-plot factor. Juniper intake did not vary between species (P = 0.54) or supplement treatments (P = 0.93; 4.7 g/kg0.75). Total intake (TI), basal diet intake (BDI), and sudangrass intake (SGI) were unaffected by supplements, were higher for sheep than goats (P 0.75, respectively. Total VFA, acetate (Ac), and propionate (Pr) increased with juniper in period 2 (P Control), species (goats > sheep), and decreased with juniper feeding in period 2 (P
