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。
http://www.chow.com/food-news/54291/is-there-a-difference-between-brown-and-white-eggs/
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
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.

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。
