孵化蛋生产者经常想知道蛋壳颜色和蛋壳质量之间是否存在关系。在本实验中，记录了肉种鸡的蛋壳颜色、比重和其他蛋壳质量特征，以确定蛋壳颜色变化对蛋壳质量的重要性。采用三种饲喂程序（随意采食、快速饲喂和慢速饲喂）从四种禽类（Avian 24K、Cobb 500、Hubbard Hi-Y 和 Shaver Starbro）收集鸡蛋。使用图像分析软件来评估壳颜色。随意采食时出现了壳颜色和壳质量之间可能的关系。蛋壳的棕色越深，比重就越高，因此蛋壳的质量就越高。虽然这种相关性很小，但非常显着。菌株对贝壳颜色的影响似乎比喂养处理更大。然而，与随意喂养的鸟类中发现的类似，壳颜色和壳质量之间的关系并不明显。
Hatching egg producers hav often wondered if there could be a relationship between eggshell color and shell quality. In this experiment, eggshell color, specific gravity, and other shell quality characteristics were recorded in broiler breeders to determine the significance of variation in shell color on eggshell quality. Eggs were collected from four strains of birds (Avian 24K, Cobb 500, Hubbard Hi-Y, and Shaver Starbro) on three feeding programs (ad libitum, fast feed, and slow feed). Image-analysis software was used to assess shell color.A possible relationship between shell color and shell quality appeared with ad libitum feeding. The darker brown the eggshell, the higher the specific gravity and thus the greater the shell quality. While this correlation was small, it was highly significant. Strain appeared to have a greater effect on shell color than did feeding treatment. However, a relationship between shell color and shell quality, similar to that found in the ad libitum-fed birds, was not apparent.
