Abstract
An experiment was carried out to determine the effect of fermented purple sweet potato (Ipomoea batatas L) skin in diets on feed and anthocyanin consumption, carcass characteristics antioxidant profile and meat texture of Bali duck.. Five treatment diets were used in a completely randomized design (CRD) consisted of control diet A (diet without containing purple sweet potato skin), diet B containing 10% purple sweet potato skin, diet C containing 10% fermented purple sweet potato skin, diet D containing 20% purple sweet potato skin, diet E containing 20% fermented purple sweet potato skin.Each treatment consisted of four replications and each replicate had five ducks. The variables observed were feed and anthocyanin consumption,slaughter weight, carcass weight, carcass percentage, carcass physical composition, meat antioxidant profile (capacity antioxidant (CA), malondialdehide (MDA), and superoxide dismutase (SOD). Experiment results showed that diets with fermented or unfermented purple sweet potatoin diets treatments B, C, D, and E increased the anthocyanin consumption, slaughter weight, carcass weight, carcass percentage and meat percentage of duck carcass but decreased their fat and skin. Fermented purple sweet potato (Ipomoea batatas L) skin in C and E increased the antioxidant capacity(AC) and superoxide dismutase (SOD) while treatment B and D were not significantly different (P>0.05) to the control group. Malondialdehide (MDA) of the duck meat in treatment B,C, and D were significantly lower (P<0.05) compared to the control diet. Treatment E significantly increased the perimesium and endomesium of meat texture , but its experiment was not significantly different to the control group. It was concluded that substitution of fermented purple sweet potato (Ipomoea batatas L) skin in diets could improve of feed and anthocyanin, carcass characteristics, antioxidant profile, and meat texture of bali duck.
