P.  aConcentration of certain blood metabolites in obese pregnant and non-pregnant ewes.  c1969  aA total of 14 obese pregnant and non-pregnant ewes were compared for blood glucose, ketone bodies, lactic acid and total volatile fatty acid concentrations. A method of blood sampling which successfully eliminated the effect of excitement on the metabolites studied was devised. The mean values and standard errors for the metabolites of pregnant and non-pregnant ewes, respectively, were glucose 57 ± 4.2 mg/100 ml and 63 ± 4.2 mg/100 ml, ketone bodies 3.2 ± 0.75 mg/100 ml and 2.3 ± 0.75 mg/100 ml, lactic acid 18 ± 2.9 mg/100 ml and 19 ± 2.9 mg/100 ml, and total volatile fatty acid 1.96 ± 0.28 meq/liter and 1.58 ± 028 meq/liter. The mean blood glucose concentration was lower (P &lt 0.10) for the pregnant ewes than for the non-pregnant ewes, but there were no significant differences between pregnant and non-pregnant ewes for blood concentrations of ketone bodies, lactic acid and total volatile fatty acid. The mean blood glucose values for both the pregnant and non-pregnant ewes were higher than earlier values reported in the literature.  aBlood  aEwes  aGlucose  aMetabolites  aPregnancy  aSheep  aGlicose  aOvelha  aOvino  aPrenhez  aSangue1 aKITTS, W.
