Abstract
The aim of this study was to evaluate the effect of adding HerbaPulp (Oryza Sativa and Kaempferia galanga L) as a feed additive on the percentage of carcass yield and leg color in hybrid meat ducks. The material used was 192 one-day-old (DOD) hybrid meat ducks. This study used 192 hybrid ducks from Peking ducks and Champbel ducks. This study consisted of 6 treatments and 4 replications. The treatment used was T0: basal feed, T1: basal feed + antibiotic (Zinc bacitracin 0.1%), T2: basal feed + herbal pulp 0.25%, T3: basal feed + herbal pulp 0.50%, T4: basal feed + herbal pulp 0.75%, T5: basal feed + herbal pulp 1%. The Variables observed in this study included the percentage of carcass yield (breast, thigh, drumstick, wing, upper back, lower back) and leg color. The experimental design used a Complete Randomized Design and the research data were analysed using Analysis of Variance (ANOVA), if a significantly different result continued with Duncan^s Multiple Range Test. The results of the study also showed that the addition of herbal pulp (Oryza Sativa and Kaempferia galanga L) as a feed additive had no significant effect (P>0.05) on leg color and the percentage of carcass yield from the upper thigh, lower thigh, wing, upper back, and lower back. However, it gave a highly significant effect (P<0.01) on the percentage of breast cuts. The conclusion of this study is the supplementation of herbal pulp (Oryza Sativa and Kaempferia galanga L) as a feed additive had no significant effect on the percentage of wing, upper thigh, lower thigh, upper back cuts, and leg color, but it improved the percentage of breast cuts.
