Abstract:

The egg quality traits of 526 Huainan spotted-yellow chicken eggs were measured and correlated analysis was conducted. The results showed that, the values and its standard deviation of average egg weight, egg-shape index, shell thickness, shell strength, yolk color, Haugh unit, percentage of yolk were 43.49±2.79 g, 1.28±0.05, 0.42±0.03 mm, 4.75±0.80 kg/cm2, 5.85±1.03, 85.06±5.29 and 31.53%±3.00%, respectively. The main color of shell color was pink and had a percent of 69.0. There were significant correlation between egg weight and shell strength, shell thickness and shell strength, yolk color and Haugh unit, Haugh unit and percentage of yolk (P<0.01). The egg weight presented a significant correlation with shell thickness (P<0.05). This study suggested that eggs of Huainan spotted-yellow chicken had high quality and egg weight should be increased for genetic improvement of egg quality in future, considering the correlation between other egg quality traits.
