Abstract

This study aimed to identify the best starter levels of commercial cultures and incubation time on crude protein (CP), crude fiber (CF), extract ether (EE), and nitrogen-free extract (NFE) of amofer corn straw. This research used a completely randomized design with ten treatments and four replications. The treatments were the additions of EM4 (EM) and M21 decomposer (MD) at different levels (control/without amofer; 0.04 % EM; 0.06 % EM; 0.04 % MD; and 0.06 % MD) and incubation times (4 weeks and 2 weeks). The obtained data were analyzed by analysis of variance (ANOVA), then continued with the Duncan Multiple Range Test (DMRT). The result showed that the use of commercial starters with different fermentation times could increase the CP and NFE levels while reducing the EE and CF of amofer corn straw. The most effective treatment was the addition of 0,04 % EM and 2 weeks incubation which contained CP of 5.9415 %, CF of 37.8545 %, EE of 4.5183 %, and NFE of 32.4245 %.

Abstract

This research aimed to evaluate the addition of M21 Decomposer (MD) and urea (U) on the Dry matter digestibility (DMD) and Organic matter digestibility (OMD) in vitro. There were five treatments and five replicates. The treatments in this study were the addition of MD and U at different levels. namely R0 = Corn cob without amofer/control; R1 = Amofer Corn cob plus 0.04% MD+3% U; R2 = Amofer Corn cob plus 0.06% MD+3% U; R3 = Amofer Corn cob plus 0.04% MD+5% U; and R4 = Amofer Corn cob plus 0.06% MD+5% U. The obtained data were subjected to Analysis of Variance and continued by an Orthogonal Contrast. The result showed that the treatments significantly affected (P<0.05) both DMD and OMD digestibility. The digestibility of amofer corncob was higher than the non-amofer that exhibited 17.982±2.4409% DMD and 26.024±3.009% OMD. The highest DMD and OMD digestibility was observed in R4. i.e.. 24.655±4.858% and 34.276±5.176%. respectively. In conclusion. the best level in the incorporating MD and U is at MD 0.06% and U 5% could improve DMD by 6.673% and OMD by 8.252%.
