Nutrient Intake and Digestibility of Kacang Goat Received Rations Containing Solid Waste of Herbal Industry

Abstract

This study was aimed to determined the effect of substitution of king grass with solid waste of herbal industry (SWHI) in the rations on nutrient intake, digestibility and average daily gain (ADG) of kacang goat. The diet was basal ration for Kacang goat with forage to concentrate ratio (F:C)= 50:50.  The experiment  was designed in completely randomized design with 3 treatments: R0 = 50% king grass: 0% SWHI (control treatment), R20 = 30% king grass: 20% SWHI, and R30 = 20% king grass: 30% SWHI. The in vivo experiment showed that no differences of dry matter intake among treatments (P<0,05) butorganic matter intake of kacang goat increased significantly (P <0.05) in line with the increasing ofSWHI concentration. The ration containing SWHI decrease the digestibility of dry matter (DM), organic matter (OM) and crude protein (CP) (P <0,05) but no differences found in ADG between control.   It was concluded that SWHI could be used as king grass substitution up to 30% in ration without decreasing nutrient intake and weight gain of kacang goat, although the level of ration digestibility was lower with the increasing of SWHI concentration.
