This study aimed to determine the effect of adding mahogany ( Swietenia mahagoni ) leaves as a source of tannins on purine derivatives (DP) excretion in urine and rumen microbial protein synthesis of merino sheep. This study used 12 sheep with an average body weight of 32.46 ± 5.186 kg which were given additional tannin from mahogany leaves in the feed. The data were analyzed using a completely randomized design analysis unidirectional pattern, with three different levels of tannin treatment (0%, 1.5%, and 3%) and four replications. The feed given during the research process was in the form of forage and concentrate on a ratio of 60% and 40%. The administration was given 2 times a day with a ratio of 60% and 40% in the morning and evening. There was no significant effect (P >0.05) on the addition of Mahogany leaves for the excretion of purine derivatives in urine and microbial protein synthesis of the rumen of Merino sheep.
