| dc.description.abstract | 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. | en |
