研究母鸡下蛋的北卡州立大学教授Ken Anderson

北卡州立大学农业和生命科学学院(http://harvest.cals.ncsu.edu)，食物、生物处理和营养科学系的肯·安德森(Ken Anderson)教授,属于北卡州立大学（http://www.ncsu.edu）和北卡农工州立大学联合成立的“北卡罗来纳合作推广服务”(http://www.ces.ncsu.edu/)，同时也是国家鸡蛋质量学校(http://www.neqs.org/)的负责人。

偶然间看到安德森教授谈到白壳鸡蛋和棕壳鸡蛋区别。

The difference is that they are more expensive. At CHOW’s local Safeway, one dozen Grade AA, extra-large white eggs from Lucerne sell for $3.19. Their brown counterparts, same size and grade, go for $3.98 per dozen. So why the higher price?

大意：（棕壳鸡蛋和白壳鸡蛋区别）区别是棕壳鸡蛋更贵。在CHOW本地Safeway店里面一打AA级超大号的白壳鸡蛋大概$3.19。而对应的棕壳鸡蛋价格则是$3.98，为什么更贵呢？

Hens that produce brown eggs are larger than white-egg-producing hens, and require more feed and care; that extra expense is passed on to the consumer. Although it might be cheaper to raise white-egg-producing hens, brown eggs continue to sell well, so they’re still a smart business choice for farmers.

下棕壳鸡蛋的母鸡被产白壳鸡蛋的鸡更大，因此需要更多的饲料和照顾；而那额外的成本就转嫁到消费者头上。机关饲养下白壳鸡蛋的母鸡会更便宜，但是棕壳鸡蛋却卖的更好，所以他们仍旧农场做小生意的的更明智的选择。

It’s awidespread belief that hens with darker feathers and red earlobes produce brown eggs, while hens with white feathers and white earlobes produce white eggs. Kenneth E. Anderson, professor and poultry extension specialist at North Carolina State University, says it’s not an absolute rule, though he does acknowledge that most hens with white earlobes produce white eggs, and mosthens with red earlobes produce brown eggs. Ultimately, eggshell color is a matter of a chicken’s genetics.

大家普遍认为毛色更深且有红肉垂的母鸡下棕壳鸡蛋，而白色羽毛且白色肉垂的母鸡下白壳鸡蛋。北卡州立大学教授和家禽推广专家肯尼斯·E·安德森教授认为，这个也不全对，不过他也承认大部分的有白色肉垂的母鸡下白壳鸡蛋，而大部分有红色肉垂的母鸡下棕壳鸡蛋。最根本的原因是，鸡蛋壳的颜色源于鸡的品种。

 

Hen breeds are predisposed to produce a certain color egg, says Clint Hickman, an owner ofHickman’s Family Farms. Which breed of hen will lay which color egg is pretty much well known in the industry: White Leghorns are the most popular breed used to lay white eggs, and Rhode Island Reds are most often used for laying brown eggs. (Check out thischicken chart to see what color eggs other hen breeds lay.)

希克曼家族农场主克林特·希克曼说道，下不同颜色鸡蛋的母鸡都是预先分别饲养的。业界对于哪些品种的母鸡下什么颜色的蛋已经非常清楚了：白色来亨鸡是下白壳鸡蛋的最常见的品种，而罗得岛红鸡则最主要用来下棕壳鸡蛋。
