<![CDATA[ABSTRACTThis research was designed to evaluate nutrient digestibility, mentioned as Total Digestible Nutrient of diet containing PUFA (polyunsaturated fatty acid) - concentrate supplemented with yeast and Curcuma xanthorrhiza Roxb for dairy goat. Twenty Ettawah crossbred goat in late lactation were allocated into 6 treatments in randomized block design. The treatments were PD0: PUFA-diet with no supplement, PDA: with Asifit, PDY: with 0.5% yeast, PDC: with 1.5% curcuma, and PDM: with 0.5% yeast + 1.5% curcuma. The PUFA-diet contained of 80% PUFA- concentrate as basic diet and 20% Pennisetum purpureum. While the PUFA sources were roasted ground corn and roasted soybean meal, and corn oil. Results showed that intakes of DM, OM, CP, CF, NFE, ADF, and GE were not affected significantly by dietary treatments. However, EE and NDF among treatments were different significantly (P<0.05), whereas Ca and P were different very significantly (P<0.01). High nutrient contents (DM, OM, CP, EE, CF, NDF, and GE) were found in feces of the goat with curcuma diet (PDC), consequently showed the opposite effects by giving the lowest digestibility (P<0.05 or P<0.01) of these nutrients. Total digestible nutrient (TDN) of PDY and PDM were markedly higher (79.89% and 79.37%, respectively) than that in other diets, such as being the lowest was in PDC (69.94%). This suggested that the yeast concentration of 1.8 108cfu/d, given singly or in combination with 1.5% Curcuma could be considered as the right level for improving nutrient digestibility in the late lactation goat in our study.Keywords: curcuma, dairy goat, PUFA-diet, TDN, yeast]]>
