| Abstract | The objective of this study was to evaluate the effect of high tannin and polyphenol plants as feed additive for fattening beef cattle with different ratios of roughage to concentrate on gas production kinetic, digestibility, total volatile fatty acid and microbial biomass production using in vitro gas production techniques. The experimental design was a 2 x 5 factorial arrangement in a completely randomized design (CRD) with 5 replications. Factor A had two ratios of R:C (A1 =30:70; A2 = 70:30). Factor B (additive) consisted of five types which were B1= Spondias pinnata (L.f.) Kurz, B2 = Phyllanthus emblica, B3 = Azadirachta indica, B4 = Cysteamine-nitrate-mangosteen peel and B5 = no additive. There was no significant interaction between these factors, and high concentration feed (R:C, 30:70) showed significantly improved in vitro gas production kinetics and degradability. Supplementation of high tannin and polyphenol plant did not alter the accumulative gas production, gas production from soluble fraction (a), gas production from degradable fraction (b), potential of gas production, and DM disappearance (P>0.05). Incorporating high tannin and polyphenol plants, such as cysteamine-nitrate- mangosteen peel and Phyllanthus emblica may have enhanced ME and microbial biomass compared to the control group (P<0.05). Therefore, the use of local plants with high tannin and phenolic content can be used as natural supplements that could improve rumen fermentation efficiency. However, the inclusion of high tannin and polyphenol plants in fattening feed should be conducted for further study in an in vivo trial. |
