The Effectiveness of Biacid (Organic Acid and Essential Oil) as Substitute for Antibiotics on Ileal Characteristics of Broilers

The research was aimed to evaluate the characteristics of ileal broiler with the inclusion of Biacid as feed additive on broiler feed. The material was used 900 DOC broiler with average body weight 45.34-4.403 g and coefficient of diversity 9.71 % and reared for 35 days. The method that used in the research was experiment using completely randomized design with 4 treatments and 5 replications. The feed treatments consisted of P0=basal feed without Biacid, P1=basal feed + Biacid 0.075 %, P2=basal feed + Biacid 0.100 %, and P3=basal feed + Biacid 0.125 %. The variables measured were villus number, villus height, villus surface area,and crypt depth. The data was analyzed use Analysis of Variance (ANOVA) and Duncan's Multiple Range Test (DMRT). The result showed that the inclusion of Biacid had a significant effect (P<0.05) on villus high and crypt depth, but not significant effect (P>0.05) on villus number and villus surface area. The conclusion research that is addition 0.075 % Biacid give the best result from villus total, villus surface area, and crypt depth at level.
