Abstract: Objective: The objectives of this study were to evaluate the effect of supplementation of an ammoniated palm frond-based diet with Direct-Fed Microbials (DFM) and Virgin Coconut Oil (VCO) on the in vivo methane production, Dry Matter Intake (DMI), Organic Matter Intake (OMI), Daily Gain (ADG) and nitrogen retention of Bali beef cattle. Materials and Methods: The DFMs used in this study were Saccharomyces cerevisiae (SC) and Bacillus amyloliquefaciens (BA) and the Virgin Coconut Oil (VCO) contained 51.95% C12:0. In a pilot study, 16 male Bali cattle were assigned treatments in a randomized complete block design. Cattle were fed a basal diet containing (dry matter basis) 40% ammoniated palm frond and 60% concentrate and the treatments were: a) control, b) SC 1% DM, c) SC 0.5% DM + BA 0.5% DM and d) SC 1% DM+VCO 2% DM. Data were analysed by analysis of variance (ANOVA) and differences among means were tested using Duncan’s multiple range test (DMRT). Results: The results showed that supplementation with SC, SC+BA, SC+VCO significantly (p<0.05) reduced DMI and OMI but that the treatments were also able to increase ADG by 0.63, 0.63 and 0.71 kg day–1, respectively. Supplementation with SC+VCO increased the feed efficiency and reduced methane gas production by up to 20.63% compared to the control and nitrogen retention tended to decrease with DFM and VCO supplementation. Conclusion: These results suggest that supplementation with SC+VCO generates the best results in Bali beef cattle growth performance, methane gas production and feed efficiency.
