Effect of Beak Color on Growth Performance and Carcass Characteristics of Pekin Ducks

Background: Pekin ducks are broadly raised over the world, particularly in Asia continent, moreover, they famous for delightful taste of Beijing roast duck around world. The aim this study was to explore effect beak color on growth performance, carcass traits and sexual dimorphism ducks. Methods: A total 250 one-day-old were separated according into two groups, yellow (YB) blue (BB). Body weight body gain recorded from first week marketing age (6 wks). Carcass taken at (20 /each phenotype). Sexual calculated live age. Result: show that YB have significantly heavier 1 5 wks compared BB, however BB higher 3 4 At age, differences between phenotypes not significant. Generally, rate mortality defect ratio affecting color, relative lower There no traits. However, most BB. In conclusion, we concluded has a significant performance
