Curcuma xanthorriza Roxb. as Feed Additive on the Carcass and Fat Weight Percentage, Meat Nutrient, and Nutrient Digestibility of Super Kampong Chicken

The purposes were to analyze the effect of Curcuma xanthorriza Roxb. as a feed additive towards
super kampong chicken (Indonesian native/local chicken - Gallus gallus domesticus Linnaeus, 1758) and to
determine the most effective level of curcuma xanthorriza for the chicken. Completely Randomized Design
(CRD) was used in this research through experimental design. Treatments in this research covered T0:
Curcuma xanthorriza as feed additive 0.0 % (parameter), T1: Curcuma xanthorriza as feed additive 0.33 %,
T2: Curcuma xanthorriza as feed additive 0.67 %, and T3: Curcuma xanthorriza as feed additive 1.00 % with
five replications. The result indicated that Curcuma xanthorriza as a feed additive had a significant effect on
income over feed cost and carcass weight percentage, but it had no significant effect on abdominal fat weight
percentage, feed efficiency, meat dry matter content, meat organic matter, meat ash content, dry matter, and
organic matter digestibility in super kampong chicken. The best treatment was curcuma by 1 % as feed
additive due to the increase of carcass weight percentage by the value was 69.60 %.
