Abstract

This research aims to determine effect of a direct-fed microbial (DFM) on digestibility (dry matter (DM) , organic matter (OM) and crude protein (CP)) and growth performances such as feed intake, body weight gain and feed efficiency of Bali steer fed oil palm trunk fermented as base diet with the addition of (DFM) of Saccharomyces cerevicea and Pediococcus sp. The experimental design used was a randomized block design consisted of 4 treatments and 4 replicates using 16 Bali steers with an average weight between 120-150 kg per head. Feed treatment applied as follows: A: 70% concentrate+30% fermented oil palm trunk; B: Ration A+1% Saccharomyces cerevicea; C: Ration A+1% Pediococcus sp; D: Ration A+0.5% Saccharomyces cerevicea+0.5% Pedicococus sp. The results showed that the treatment provides highly significant effect (P<0.01) on the digestibility of DM, OM CP, feed intake and body weight gain, whereas a significantly effects (P<0.05) to feed efficiency. It can be concluded that the best treatment was the used of ration D with digestibility DM, OM and CP were 70.42%; 73.04% and 69.27% respectively. The ration D also showed that the body weight gain: 1.0 kg/day with feed intake: 4.31 kg and 23.13% feed efficiency.
