Effect Of Curcuma (Curcuma Roxb Xanthorrhiza) Meal As Feed Additive In Broiler Rations On Performance And An Antibody Titres Against ND

With the increasing public awareness of Indonesian in healthy nutrition, it is resulted in demand for animal products that are healthy and free of antibiotic residues also increased. One natural feed additive used as a substitute for antibiotic synthesis is Curcuma Roxb xanthorriza, which is often used by humans to increase of appetite and cure various diseases.

The aim of this research is to determine the influence of the ginger in broiler diets to the performance, the percentage of the carcass, and abdominal fat. A Completely Randomized Design was used to analyze the data. Two hundred DOC were divided into 4 treatment groups with 5 replications and 10 DOC in each replication. Four treatment diets were control diet with 0% of curcuma meal (R0); 1% of curcuma meal (R1), 2% of curcuma meal (R2), and 3% of curcuma meal (R3). The parameters observed were feed consumption, gain of body weight, feed conversion, percentage of carcass, abdominal fat and ability as a antibody titre against ND. The results of research showed that feed consumption, gain of body weight, carcass percentage, and abdominal fat of broilers were significantly different (p
