Abstract

Abstract:

The purpose of this study is to understand the internal relationship between feather color and production traits of Shaoxing ducks. On the basis of the reciprocal cross experiment, 836 Shaoxing ducks with good health were selected. By comparing the body weight, slaughter performance, and meat quality of Shaoxing ducks with different feather colors of the same age, the influence of feather color on the production performance of Shaoxing ducks was analyzed. The results showed that the feather color of Shaoxing ducks was correlated with body weight, chest muscle weight, abdominal fat weight, abdominal fat percentage, chest depth, chest width, tibia length, hip bone width, tibia circumference, and pH value of leg muscle, and the feather color of Shaoxing ducks affected their growth performance. This study provided theoretical basis for the development and utilization and the breeding of high-quality Shaoxing duck with white feather.

Key words: Shaoxing duck, feather color, production traits
