The use of feed additive of turmeric powder aimed to improve the growth performances of rabbits. Conducted this research in the Riang Gede Village, Penebel District, Bali Province, in July-October 2018. The rabbit used were 20 aged 8-week-old male crossbred rabbits (New Zealand White and Local Rabbits). The design experimental used was a completely randomized design with four treatments and five replications with details of treatment, namely ration without turmeric powder (P0), ration with 0.5% turmeric powder (P1), ration with 1% turmeric powder (P2), ration with 1.5% turmeric powder (P3). The parameters observed were daily weight gain, final body weight, feed intake, and feed conversion ratio (FCR). Turmeric powder has a positive impact on feed intake, daily body weight gain, FCR, and final body weight of rabbits. The addition of 1.5% turmeric powder had the highest feed intake at first and third-month research 72.98 g/head/day and 106.26 g/head/day. The turmeric powder of 1.5% in ration had the greatest feed conversion ratio of 3.85 with a final body weight of 1902.2 g/head.
