| This experiment aimed to study effects of levels of rubber seed kernel (RSK; 0, 20 and 30%) and palm kernel cake (PKC; 20 and 30%) in concentrate on dry matter intake and rumen fermentation. Six goats with average liveweight 22±2 kg were randomly assigned according to a 3x2 factorial arrangement in a 6x6 Latin square design to receive six diets. Signal hay was given on an ad libitum basis as the roughage. It was found that, there were interactions between RSK levels and PKC levels with respect to total DMI (kg/d) and goats receiving 30% RSK had lower values (p<0.05) than those receiving 0 and 20% RSK, respectively. Digestion coefficients of nutrients (DM, OM and CP), pH and NH3–N were similar (P>0.05) for all diets and all treatment were within the... |
