This research was aimed to observe the effect adding cinnamon (Cinnamomum burmanni Ness ex Bl.) as source of cinnamaldehyde in diet on methane production and thin tail sheep performance. The first experiment was the effect of cinnamaldehyde on methane production and nutrient digestibility by in vitro. Cinnamaldehyde were added 0, 200, 400, and 600 mg/kg DM. The second experiment was the effect of cinnamaldehyde on digestibility and livestock performance. Nine thin tail sheep were plotted in three groups. Each groups were given king grass:concentrate (65:35) in the diet without cinnamaldehyde (control) and adding of cinnamaldehyde with 300 dan 600 mg/kg DM. The sheeps were maintained for eight weeks. Collection stage were done in the last of 7th week. The collections were involved of feeding collection, feeding residue, and feses during one week. The data were analyzed by completely randomized design and followed by orthogonal polynomial. The result of experiment showed that the adding cinnamaldehyde of 600 mg/kg level, did not influence methane production, microbial activity, volatile fatty acids, pH, dry matter digestibility (DMD), and organic matter digestibility (OMD). Adding of cinnamaldehyde 600 mg/kg level descreased (P<0.05) of ammonia from 25.85 to 19.91 mg/100 mL. The result of second experiment showed that the adding cinnamaldehyde of 600 mg/kg level did not influence of DMD and OMD. However, the adding cinnamaldehyde of 300 and 600 mg/kg level increased (P<0.05) crude fiber digestibility (CFD) from 77.88 to 79.75 and 79.59%, descreased crude protein digestibility from 89.57 to 88.11 and 86.14% and increased (P<0.05) thin tail sheep performance of DM intake from 660.35 to 735.04, and 760.84 g/sheep/day, average daily gain from 67.86 to 94.03 and 111.31 g/sheep/day, and descreased feed conversion ratio from 9.94 to 7.86 and 7.02. The adding cinnamaldehyde 600 mg/kg DM level descreased ammonia with in vitro digestibility and 300 mg/kg DM level had increased CFD and thin tail sheep performance.
