Glucose turnover (i.e. glucose entry and utilization rates) in fed and 48 h starved goats during pregnancy and lactation was determined using a continuous infusion of [U-14C)- and [3-3H]glucose. 2. Glucose synthesis and utilization increased during pregnancy and lactation in fed but not in starved goats. 3. Recycling of glucose-C was approximately 10% in fed animals and 15-20% in starved animals and was unaffected by the stage of pregnancy or lactation. 4. Plasma glucose concentrations were maintained during pregnancy and lactation in fed goats but decreased during 48 h starvation in pregnant goats. Little change was seen in the plasma concentration of lipids and their metabolites during pregnancy and lactation in fed goats, but increases were observed after 48 h starvation. 5. The control of glucose metabolism in ruminants during pregnancy and lactation is discussed.  aBlood  aFatty acids  aGlycerol  aGoats  aInsulin  aLactation  aPregnancy  aReproduction  aCaprino  aGlicose  aLactação  aMetabolismo  aPrenhez  aReprodução  aHydroxybutyrates1 aFAU KNER, A.1 aPEAKER, M.  tThe British Journal of Nutritiongv. 47, n. 1, p. 87-94, Jan. 1982.
