摘要：An attempt was made to search effect of several AGP replacers on digestibilities amino acid determined by using Acid Insoluble Ash Method in Mojosari ducks. This research used 40 ducks, raised at individual cage to facilitate 9 treatments and 4 replications. The treatments consisted of P1: basal feed + antibiotic; P2: basal feed + 1% sardine oil + 0.5% tomato powder; P3: basal feed + 2% sardine oil + 0.5% tomato powder; P4: basal feed + 1% sardine oil + 1% tomato powder; P5: basal feed + 2% sardine oil + 1% tomato powder; P6: basal feed + 1% sardine oil + 0.5% tomato powder + 200 ppm clove oil; P7: basal feed + 2% sardine oil + 0.5% tomato powder + 200 ppm clove oil; P8: basal feed + 1% sardine oil + 1% tomato powder + 400 ppm clove oil; P9: basal feed + 2% sardine oil + 1% tomato powder + 400 ppm clove oil. Digestibility coefficient was measured by Acid Insoluble Ash method. Data were analyzed by ANOVA, and the differences was tested by DMRT. The results showed that feed consumption and digestibilities of dry matter and crude protein were not significant, therefore, digestibility of several amino acids were highly significant (P<0.01), particularly for threonine, arginine, phenylalanine and tyrosine. It could be concluded that the use of sardine oil (2%) supplemented with 1% tomato powder and 400 ppm clove oil showed the best replacer of AGP.
