Abstract
The aimed of this research to examine the effect of the concentrate to forage ratio of complete feed silage on crude protein, crude fiber, TDN and fat consumptions. Five types of the ensilage of complete feed treatments consisted of T1 = concentrate 26% + A + Napier grass 70%, T2 = concentrate 36% + A + Napier grass 60%, T3 = concentrate 46% + A + Napier grass 50%, T4 = concentrate 56% + A + Napier grass 40% and T5 = concentrate 66% + A + Napier grass 30%, that is A = (molasses 1,5% + urea 0,5% + salt 0,5% + mineral mix 1,5%). Twenty of local male sheep with a body weight 12.5 – 22.5 kg divided into 4 blocks were used in this experiment. The parameters measured were the consumptions of crude protein, crude fiber, TDN and fat. The results showed that treatment had highly significant effect (P <0.01) on consumptions of crude protein, crude fiber, and TDN, but had a significant effect (P<0.05) on fat consumption. The conclusion of this study that the P3 treatment is the best concentrate to forage ratio of complete feed silage for fattening because it has the highest consumptions of crude protein 131.01 ± 4.05, crude fiber 103.06 ± 3.33, TDN 655.80 ± 18.74 and fat 55.84 ± 1.83 gram/day/head. © Published under licence by IOP Publishing Ltd.
