Prayogi PW, Martatmo P, Subagyo YBP. 2009. Influence of temulawak (Curcuma xanthorrhiza) flour addition in ration on carcass and abdominal fat percentage of male local rabbit. Biofarmasi 7: 42-47. Increasing people’s demand for rabbit meat was the reason to increase carcass percentage and decrease fat content, especially abdominal fat, so it can increase the meat productivity of rabbit. To increase rabbit productivity, it could be reached by giving temulawak (Curcuma xanthorrhiza Roxb) flour in the diet condition. Temulawak, has curcumin and essential oil contents which can stimulate the passion to eat and stimulate the liver cells to increase bile product, so that the bile secretion occurs well and gives good growth. The aim of this research was to determine the influence of temulawak flour addition in ration on carcass and abdominal fat percentage of male local rabbit. This research was conducted in RT 04/21, Gulon village, Jebres district, Surakarta, Central Java for eight weeks, started on November 28th, 2007 until January 8th, 2008. This research used one-way classification of Completely Randomized Design (CRD) with 24 male local rabbits, about two months old with body weight 727.9±97.3 g. It consisted of four treatments (P0, P1, P2, P3), each treatment consisted of three replications, and each replication consisted of two male local rabbits. The treatments given were: P0 = as control, consisted of peanut tree (rendeng) 70% + concentrate 30%; P1 = control + 2% temulawak flour; P2 = control + 4% temulawak flour; and P3 = control + 6% temulawak flour. Variable measured were body weight, carcass weight, carcass percentage, carcass conformation, and the percentage of abdominal fat. The results showed that the average of four treatments (P0, P1, P2, and P3) in series for body weight were 1,014.333; 1,002.667; 961.667; and 944.667 grams, respectively. The averages of carcass weight were 428.667, 429.001, 410.667, and 390.333 grams. The carcass percentages were 42.297, 42.771, 42.717, and 40.997%. The carcass conformations were 41.593, 43.117, 40.147, and 40.450. In this research, no abdominal fat was found. The analysis of variance showed that the result was not significant in every parameter. It caused by temulawak flour supplementation until level 6% could not improve eat passion on male local rabbit yet, so that its consumption was still not significant (P≥0.05). The conclusion which could be taken from this research was the addition of temulawak flour in ration until level 6% had no effect on body weight, carcass weight, carcass percentage, carcass conformation, and the percentage of abdominal fat of male local rabbit.
