A total of261 Sudani ducks breeder (207 females and 54 drakes), 27-weeks old were used, weighed and divided into three experimental groups (each of three replicates) to investigate the effect of chamomile flower (Matericaria chamomilla L.) powder (CFP) addition at different levels (0, 1 and 3 g/kg diet) on productive performance, egg uniformity quality, hatchability and economic efficiency during the laying period. The results indicated that dietary CFP at level 1 g/kg significantly (P≤0.05) improved laying rate, egg number, egg mass, feed conversion ratio compared to the control group during the overall experimental period (27-39 weeks of age). In spite of, egg weight and egg uniformity, egg shape index, yolk index, haugh unit, yolk color score and hatchability percentage of fertile were not significantly affected by different levels of dietary CFP, while eggshell thickness was significantly increased. Feed consumption and fertile percentage of Sudani ducks were significantly decreased affected by levels of CFP. Economic efficiency was also improved for Sudani ducks fed diet supplemented with 1 g CFP/kg. From the obtained results, it could be concluded that dietary addition of 1 g CFP /kg for Sudani duck breeders during the laying period may be could improve productive performance, net revenue and the relative economical returns, besides reduce the feed consumption.
