Abstract

Kacang goat is famous among Indonesian as one of small ruminant inhabits Indonesia archipelago. This spesies easily to find in all across the country especially in Sumatera island. Lately, according to 2012 Bengkulu Province‟s Ruminant Survey Results it‟s population significantly decreased eventhough market demands for kacang goat product (meat) still high and economically recommended. Therefore to increase their population nationwide, it‟s reproduction capacity should be improved. In this study, There were 9 pre-weaning female kacang goat used and localized in an individual cages. They were pre-sexual mature regarding their age (3 to 5 months of age) and average weight of 8.5 ± 0.4 kg. During 56 days, they fed twice a day fresh grass ad libitum, freely drinking water and supplemented by the mixture of katuk (Sauropus androgynus L. Merr) flour and concentrate. The supllementation dozed in 3 levels: 0, 7.5 and 15 gr-1day-1. The purpose of this study was to evaluate the effect of katuk (Sauropus androgynus L. Merr) supplementation on profiles of female kacang goat gonadal hormones. The results shown that there was no significant effect of supplementation on goat‟s serum progesterone and estradiol-17β concentration. The highest serum progesterone and estradiol-17 β level were detected in goats fed by 15 gr-1day-1 of katuk flour which are 1.317 ng-1 ml-1 and 83.373 pg-1 ml-1, respectively. In comparison, non-supplemented goats gonadal hormones level were the lowest. We can conclude that the supplementation of katuk flour can affects the profile of pre-weaning kacang goat‟s gonadal hormones.
