Scottsdale: Dairy Goat Journal, 1982. p. 362c1982  aBlood and rumen fluid samples were obtained from nine growing Toggenburg x Saanen wethers and nine Suffolk x Barbados wethers averaging 27 and 45 kg respectively. Rations consisting of 35, 50, or 65 percent wheat straws were fed over three periods. Sheep had higher blood potassium, rumen fluid pH, packed cell volume, and blood calcium than did goats. Goats had higher ruminal osmotic pressure, molar percent propionic acid and serum urea nitrogen than did sheep. There were no statistically significant differences in levels of serum sodium, chlorine, CO2, total protein, albumin or glutamo oxalo-transaminase. The molar percent acetic increased and the molar percent butyric acid decreased in the rumen fluid of both species as concentration of wheat straw increased rations. There was a significant species by treatment interaction on osmotic pressure of the plasma, serum alkaline phosphatase, and total concentration of volatile fatty acids in rumen fluid. Correlations (goats and sheep combined) of several blood rumen fluid parameters with previously reported digestibility coefficients are reported  aChemical composition  aGoats  aSheep  aCaprino  aComposição química  aOvino  aRúmen  aFluido ruminal  aLíquido ruminal  aRumen fluid  aUSA1 aJOHNSON, W.
