Background: Duck meat consumption has been popularized and augmented during the past few decades and the better growth necessitates optimal mineral requirements. Over the past few decades, the consumption of duck meat has increased and become more popular and its improved growth requires the right minerals. Therefore, the present study was carried out conducted to find out the effect of supplementation of different levels of trace mineral mixture on the performance of White Pekin ducks for meat production purpose. Methods: 180 day-old White Pekin ducks (180; day-old) were divided into three groups; with each group consist of four replicates; and each replicate had 15 ducklings. Three experimental diets feeds were prepared by supplementing a standard starter feed with TMM @ of 100 g (TMM-100), 200 g (TMM-200) and 300 g (TMM-300) per 100 kg diet; and were offered randomly to the above three groups for eight weeks of age. Result: The day-old body weight (51.67- 52.02, g) and 8th week body weight (2155.02- 2176.17, g) of the ducklings were similar among the groups. The daily feed intake at the 8th week of age in TMM-100 group (156.62 g) was similar to both TMM-200 group (154.77 g) and TMM-300 group (160.31 g). However, the cumulative feed intake up to 8 weeks in TMM-100 group (6.83 kg) was similar to TMM-200 group (6.83 kg) and both the groups were recorded higher feed intake than the TMM-300 group (6.60 kg). The feed conversion ratio up to 8 weeks (3.07-3.17) was similar among all the experimental groups. The eviscerated weight percentage (68.98-70.27) was similar among all the treatment groups. There is were no significant differences in various body parts as percentage of eviscerated weight i.e. legs (19.89-20.51), breast (27.99-29.11) and wings (15.57-17.08) among the experimental groups. However, the back expressed as percentage of eviscerated weight in TMM-100 group (23.11) was similar to TMM-200 group (24.23), but lower than TMM-300 group (24.69) recorded higher weight than other two groups. It can be concluded that trace mineral mixture can be supplemented @ 100- 200 g per 100 kg feed in the diet of White Pekin ducks up to 8 weeks of age for resulted better growth rate and meat production.
