This research had run during dry seasons in the farm of farmer in Tulungagung District, East Java Province of Indonesia for 3 months. This study was carried out for measurements for average daily gain (ADG), dry matter (DM), organic matter (OM) and Crude Protein (CP) consumptions and digestibility, also feed convertion ratio (FCR) on the effect of Hibiscus rosa-sinensis(H r-s) leaves supplementation in daily ration for Ettawah Crossed Bred Goats (ECBG). The experiment method was used in this study and 12 (twelve) heads of ECBG in average of weight 17.33 ± 0.33 kg and 8 months age as the object of research. The ECBGs were divided into 3 groups of treatment supplementation level in main ration. Individual cages were used in this research. The Level of H r-s leaves as supplement were 0% (P0); 2% (P1) and 4% (P2) based on total DM ration. Data of nutirent consumption were collected dail, data of nutrient digestibility were collected during 1 week in the and of research used in vivo technique. The results, Level of supplementation of H r-s leaves giving significantly different (P≤0.05) on ADG.The highest ADG in P2 which was the highest level of supplementation of H rosa-sinensis leaves. That was strongly indicate that leaf of H r-s in the daily ration especially in 4% level giving impact to metabolism especially in absorption and support to animals for growing fast. From the resulr of FCR, ration for ECBG have to evaluation for ration formulate using Hibiscus rosa sinensis leaves as supplement or substitute in ration especially for having ADG better and decrease FCR value.
