Abstract: The use of sardine oil to replace soybean oil has been reported to increase omega-3 in egg, but the disadvantages for breeder are of smaller hatching egg weight and production of smaller progeny. This could be overcome by the use of antioxidant to protect the oil from oxidation. Tomato powder is one of a good antioxidant source. While clove oil is reported to exert antimicrobial factor which might be able to alter digestibility and or absorption of nutrients leading to improve egg production. Current research was carried out to evaluate effect of different types and levels of additive on laying duck performances and nutrient total tract digestibility. In the first experiment, ninety six female ducks were used, they were offered 160 g feed per day and water was provided ad libitum. The dietary treatments consisted of P0 : basal feed containing 2% soybean oil, P1: basal feed of which 1% of soybean oil was replaced with 1% sardine oil, P2: basal feed of which 1% of soybean oil was replaced with 1% sardine oil and added with 1% tomato powder and P3 : basal feed of which 1% soybean oil was replaced with 1% sardine oil and added with both 1% tomato powder and 100 ppm clove oil. Next, in the second experiment, 30 ducks were used to measure digestibility of duck feed added with similar additives to the first experiment. The dietary treatment consisted of P0: basal feed without antibiotics, P1 basal feed of which 1% soybean oil was replaced with 1% fish oil+1% tomato powder, and P2 basal feed of which 1% soybean oil was replaced with 1% fish oil+1% tomato powder + 200 ppm clove oil. Data were statistically analyzed for one way analysis of variance, different among treatments was tested by Duncan Multiple Range Test. The result of first experiment showed that highly significant improvements were reported for HDP and IOFC (P<0.01) and significantly improved (P<0.05) FCR. However, in the second experiment the treatments did not significantly influence essential amino acid digestibilities. It is concluded that improvement of laying performances of duck was due to the use of natural feed additive comprising of fish oil, tomato powder and clove oil, but the improvement was not attributed from digestibilities of nutrients.
