English Abstract
In the recent commercial poultry nutrition, n-6 fatty acids (n-6 FA), particularly linoleic acid (C18:2, n-6) is the major compound of polyunsaturated fatty acids (PUFA) which is derived from common dietary oil (corn or soybean oil) used in feed formulation. On the other hand, the use of fish oil as n-3 FA source become popular due to immune-enhancing properties. This study was conducted to evaluate the use of dietary oil and its combination with tomato powder on laying performance, egg quality and reproductive performance of Mojosari duck. Materials used in this study was 140 Mojosari ducks (consist of 120 females and 20 males), aged at 40 weeks old. Initial egg mass of female duck, before experimental treatment was 52.67 ± 5.23 g/bird (coefficient of variation was 9.93%), while fertility of male ducks before experimental treatment was 95.91 ± 4.64 % (coefficient of variation was 4.84%). Ducks were randomly allotted into 5 dietary treatments with 4 replications (each replication consisted of 6 female and 1 male ducks). Dietary treatments used were T0: diet with 2% soybean oil (control), T1: diet with 1% soybean oil + 1% fish oil, T2: diet with 2% fish oil, T3: diet T1 + 1% tomato powder and T4: diet T2 + 1% tomato powder. Dietary treatment was lasted for 6 weeks (40-45 weeks of age). Data was analyzed by using One-Way Analysis of Variance according to Completely Randomized Design. Treatments means with significant effects were further analyzed by using LSD Duncan’s Test. Results showed that there was no effect (p>0.05) of dietary treatment on feed intake, HDP, egg weight, egg mass, FCR and IOFC of Mojosari duck. However, diet T3 tends to improve HDP, egg weight, egg mass, FCR and IOFC compared to T0. Dietary treatments also had no effect (p>0.05) on egg quality, except for yolk color score, which was improve (p<0.05) by the addition of tomato powder (T3 and T4 groups). Dietary oil and its combination with tomato powder did not affect (p>0.05) total SFA, MUFA and PUFA in egg yolk, but fish oil supplementation could increase (p<0.05) n-3 FA and decrease (p<0.05) n-6: n-3 FA ratio in egg yolk. Diet T3 could increase (p<0.05) transfer efficiency of n-3 LC FA without had negative effect (p>0.05) on peroxide value. Dietary treatment had no effect (p>0.05) on egg weight and hatched duckling weight, but diet T3 and T4 could improve (p<0.05) fertility, hatchability of fertile eggs and hatchability of total eggs sets. It could be concluded that the use of 1% soybean oil + 1% fish oil + 1 % tomato powder could optimize laying performance, egg quality and reproductive performance of Mojosari ducks.
