Xiangcheng Tibetan Chicken Eggs

Xiangcheng Tibetan Chicken Eggs

Xiangcheng Tibetan Chicken Eggs are a protected geographical indication product.

　　Tibetan chicken eggs are produced by Tibetan chickens that have long lived in high-altitude, cold, and oxygen-deficient environments. Due to the Tibetan chickens' adaptation to the plateau ecological environment, the nutritional content of the eggs produced under special breeding methods was analyzed. The results show that Tibetan chicken eggs contain higher levels of physiologically important trace elements such as iron, copper, and zinc, as well as higher contents of crude protein and crude fat than regular eggs. These nutrients are also more easily absorbed by the human body, giving the eggs immune-boosting benefits. In certain aspects, Tibetan chicken eggs offer higher nutritional value than regular eggs. In 2012, Xiangcheng Tibetan Chicken Eggs were certified as organic products.
