The purpose of this research was to evaluate effects of dietary sardine oil (SO) and tomato powder (TP) supplementation on laying performance and hatching egg quality of Mojosari duck. A total of 120 female and 20 male Mojosari ducks, aged at 40 weeks old, were used in this research. Ducks were randomly allotted into 20 pens (6 female and 1 male ducks for each pen) and fed 1 of 5 dietary treatments, either basal diet (control), basal diet + 1% SO, basal diet + 2% SO, basal diet + 1% SO + 1% TP or basal diet + 2% SO + 1% TP. Results showed that dietary treatments had no effect (p>0.05) on feed intake, egg production, egg weight, egg mass, feed conversion ratio and income over feed cost. Dietary treatments also did not affect (p>0.05) egg shape index, egg weight sample, yolk weight, yolk percentage, albumen weight, albumen percentage, shell weight, shell percentage, specific gravity, shell thickness and Haugh unit, but significantly affected (p<0.05) yolk color score. Supplementation of sardine oil in combination with tomato powder had higher (p<0.05) yolk color score compared to both control and sardine oil without tomato powder groups. It is concluded that dietary sardine oil supplementation until 2%, either without or with tomato powder, had no detrimental effects on laying performance and egg quality of Mojosari ducks. It is evident that supplementing Mojosari ducks diet with sardine oil in combination with tomato powder could improve yolk color score. © 2018, Fundacion CIPAV. All rights reserved.
