Plasma progesterone concentration during pregnancy and the early postpartum period was measured by radioimmunoassay in five alpacas (Lama pacos), of the Huacaya breed, whose pregnancy length had a mean of 344.8 +/- 4.4 days. Concentration of progesterone increased (P < 0.001) from low premating values (0.11 +/- 0.06 nmol/l) to greater values at 30 days of pregnancy (8.05 +/- 1.13 nmol/l) and remained high up to 2 months of pregnancy. A slight transitory decline was observed between 3 to 7 months. Concentration of plasma progesterone dropped markedly during the 72 h before parturition especially, at the day of parturition.
