Abstrak: Duck is one of a waterfowl which is potential as egg and meat producer. Duck meat has fishy odor (off-odor) and limited the consumers preference. The main objective of this research was to investigate the effect of antioxidants to reduce off-odor of duck meat. This research was conducted at the Faculty of Animal Science, Bogor Agricultural University. The cihateup male duck meat of age 10 weeks were evaluated in this experiment. The duck were raised from 1 weeks up to 10 weeks. The treatments were commercial diet as control (K); commercial feed + beluntas leaf meal 0.5% (KB); commercial feed + beluntas leaf meal 0.5% + vitamins C 250 mg/kg (KBC); commercial feed + beluntas leaf meal 0.5% + vitamins E 400 IU (KBE). The parameters observed were decreasing off-odor of cihateup s meat duck (breast, thigh) and level of consumer preference of cihateup s meat duck. The data were analyzed using ANOVA (Analysis of Variance), and significant diferrences was analyzded using Range Multiple Duncan Test. The results showed that feeding beluntas leaf meal 0.5% (KB) decreased thigh meat off-odor 12.6% and breast meat 7.1%. The results showed that feeding beluntas leaf meal 0.5% + vitamins C 250 mg/kg (KBC) decreased thigh meat off-odor 2.6% and breast meat 0.2%. The results showed that feeding beluntas leaf meal 0.5% + vitamins E 400 IU (KBE) decreased thigh meat off-odor 16.2% and breast meat 12%. The conclusion of this research was that feeding beluntas leaf meal 0.5% + vitamins E 400 IU resulted the lowest intensity of duck meat (breast, thigh) off-odor.

Abstrak: Male duck is potential as meat producer, but the ducks meat off-odor limited the consumers preference. Reducing off-odor has success with supplementation beluntas 1% in feed. However the feed conversion were higher than control. To improve feed conversion, using beluntas reduced 0,5%. To covered deficient antioxidant, try added vitamin C and E.The purpose of this research was to study the effect of feeding beluntas leaf meal, vitamin C and vitamin E in improving ducks performances (feed intake, body weight, body weight gain and feed conversion). The diet treatments were commercial diet as control (K), commercial diet+beluntas leaf meal 0.5% (KB), commercial diet+beluntas leaf meal 0.5%+250 mg C vitamin (KBC), commercial diet+beluntas meal 0,5%+400 IU E vitamin (KBE). Ninety six ducks were used for this research and divided into four treatments and three replications. The ducks were reared from one week up to 10 weeks of old. The parameter measured were feed intake, body weight, body weight gain and feed conversion. The results showed that feed intake did not affect. While final body weight and body weight gain of duck feeding beluntas leaf meal 0.5%+vitamin E 400 IU highest obtainable was the best feed conversion.
