Supplementation is required to satisfy mineral requirement of traditional grazing kacang goat. The present research was aimed to design of mineral supplement for better nutrition of kacang goat fed based on wild forages, rice bran and sago stalk. Crude nutrient and mineral composition of feed which are normally consumed or fed to kacang goat were analyzed for dry matter (DM), crude protein (CP), crude fibre (CF), and minerals (Ca, P). Samples of forages were collected from three areas, i.e. coconut plantations, banana plantations and idle lands. Mineral feed was then formulated by using locally available materials: Bukit Kamang’s stone powder, roasted fresh water mussel shell meal and bone ash. The local minerals were prepared in loose and block forms and offered to 12 young kacang goat males for 14 weeks in three treatments: P0: no supplementation (control), P1: supplemented with loose local mineral, and P2: supplemented with block local mineral. Each treatment consisted of 4 goats as replication. Parameters measured included: body weight gain, feed intake, feed conversion ratio (FCR), blood minerals (Ca, P), blood hematology (hemoglobin [HGB], mean corpuscular Hb concentration [MCHC], total red blood cell [RBC], white blood cell [WBC], hematocrit concentration [HCT]) and total protein. Results showed that there were seven kinds of wild forages consumed by grazing goat. The average crude nutrient and mineral content of the forages were as follows: DM: 17.2%, CP: 16.5%, CF: 18.20%; Ca and P: 4.5 dan 2.1g/kg DM, respectively. The average daily body weight gain was 35.4, 31.7 and 41.2 g/head, and FCR was 22.8, 26.0 and 21.3 for P0, P1 and P2, respectively. The mineral concentration, total protein and hematological values of blood of P2 ranged in normal values, except WBC. It was concluded that mineral supplementation in block lick form gave positive effect on growth performance and feed utilization efficiency.
