Abstract

Five cycling Kambing Katjang does were used in this study to determine the plasma progesterone profiles in an attempt to synchronize estrus in this species using the intravaginal sponge - 'Repromap". Blood samples were taken before, during, and after the sponge was introduced. Only three does retained the sponge for a full period of twelve days treatment. Heat was not detected from any of the does for the first three days after removal of the sponge. No mucus discharge, swelling of the vulva and vaginal erythema were observed. Plasma progesterone concentration was low(< 0.3 ng/ml) during the period where the sponge was in the vagina. This plasma progesterone concentration was considered at basal level since sensitivity of the assay was 0.27 ng/ml. The sponge used in the experiment using a different set of sponge on group of three does also showed that the plasma progesterone concentration during the period when the sponge was in the vagina was also low (< o.o8 ng/ml). These results showed that the goats used in this experiment did not appear to respond to the treatment. This could be due to the low progesterone concentration in the sponge.
