Abstract


Twelve Bali steers, 11 year of age with the average body weight 110 kg, were
used as experimental animals. The steers were randomly assigned to four groups of
treatment in Completely Randomised Design (CRD). Each group of treatment fed
grass as base diet and four difierent feed block, namely A [ground cassava chips
(GCC) 30%, rice bran (RB) 38%, fresh palm oil sludge (POS) 20%, urea (U) 10%,
Salt (S) 1%, mineral-mix (MM) 1%], B [GCC 30%, RB 38%, treated EM4 palm oil
sludge (POS-EM4) 10%, U 10%, S 1%, MM 1%], C [GCC 30%, RB 28%, POS-
EM4 30%, U 10%, S 1%, MM 1%], and D [GCC 28.30%, RB 54.70%, cement
5.66%, U 9.44%, S 0.95%, MM 0.95%]. Parameters measured were DM intake,
DM, OM, CP, EE, CF, NFE digestibility, and average daily gain. Difierent between
treatments were tested using the Least Significant Difference Test. There were no
significantly different (P>0.05) between four groups of treatment (A, B, C, and D)
on DM intake (5820.96 g/d, 5471.49 g/d, 5233.80 g/d, 5740.79 g/d), DM
digestibility (72.66%, 75.35%, 74.52%, 72.23%), OM digestibility (75.53%,
77.94%, 77.24%, 75.30%), CP digestibility (65.l9%, 62.53%, 65.68%, 70.33%),
CF digestibility (75.73%, 77.47%, 77.46%, 71.74%), NFE digestibility (47.91%,
53.74%, 50.29%, 50.85%), and average daily gain (0.31 kg/d, 0.18 kg/d, 0.16 kg/d, 0.19 kg/d) respectively. EE digestibility of diets containing POS (A, B, and C) was significantly higher (91.58%, 88.68%, 91.71%, respectively) than diet containing no POS (D, 86.82%).
