<![CDATA[The research aimed to determine the effect of substitution between elephant grass with leaves midrib palm oil on dry matter intake, production of feces, digestibility of dry matter and organic; determine the effect of substitution of elephant gras and leaves midrib palm oil; and determine the relationship between digestibility of dry matter and orgnanic on goats.The research uses a randomized block design (RBD), with an average weight of goats 9-21 kg/headconsisting of three treatments with three replications ie R1 = 80% concentrate + 20% elephant grass, R2 = 80% concentrate + 20% leaves midrib of palm oil without fermentation, and R3 = 80% 5 concentrate + 20% fermented leaves midrib palm oil. The research was on October – November 2015, at the home Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. The data obtained were analyzed using analysis of variance (ANOVA) on the real level of 5% or 1%. If the treatment shows the real effect, then do a further test Duncan at 5% or 1%. Regression to determine the relationship between dry matter digestibility and organic matter digestibility at the level of 5% or 1%.The results showed substitution elephant grass with leaves midrib palm oil not significant (p>0.05) on feed consumption, but significant (p <0.05) on the production of feces and highly significant (p <0.01) the digestibility dry matter and organic.The relationship between the dry matter and organic by the equation Ŷ = - 3.629 + 1,0249x, coefficient of determination (R2) 99.77%, and the value of the correlation (r) +0.9969.
