Abstract: This study was to find the difference of nutrient component and egg quality between the ordinary ducks and Chansi ducks. A total of 50 ordinary eggs and Chansi eggs respectively produced from 300-hundred-day adult ducks were randomly selected. Egg traits such as weight, eggshell thickness and strength, eggshell color, albumen height, egg shape index, yolk color, Haugh unit etc were determined, and crude protein, crude fat calcium, phosphorus, iron, zinc, and other nutrients content were measured as well. The results indicated that as with egg weight, eggshell thickness, eggshell color, strength of eggshell and egg shape index, the differences between Chansi eggs and ordinary eggs were not significant (P>0.05), as for albumen height, Haugh unit and yolk color were very significantly higher than ordinary eggs (P<0.01), there were also more protein, calcium, zinc and iron, and less fat and phosphorus in Chansi eggs than in ordinary eggs. Therefore, the quality of Chansi eggs was better, and they contained more nutrition than the ordinary ones.

Key words: Chansi duck; egg quality; nutritional components
