Qinzhou Sea Duck Eggs

Qinzhou Sea Duck Eggs

Qinzhou Sea Duck Eggs are a product with a geographical indication for agricultural produce.

　　The "Qinzhou Ma Duck," raised on the coastal mudflats of Qinzhou City, is large in size, fast-growing, and has a high egg-laying rate. Fed on a diet of fish, shrimp, clams, and crabs, the "sea eggs" laid by these ducks are not only larger in size than ordinary duck eggs, but also have bigger yolks. There are also "yellow" eggs, whose yolks are more orange-red than ordinary ones and are high in riboflavin. Especially the "green-shell eggs" contain trace elements and have higher nutritional value.

　　There are over 2 million Ma ducks raised in the coastal areas of Qinzhou, with more than 2.4 million meat ducks slaughtered annually and over 4,000 tons of duck eggs produced. Ducklings are popular throughout Guangxi. Merchants from all regions are welcome to do business.

　　The geographical indication for Qinzhou Sea Duck Eggs as an agricultural product has been certified by experts from the Office of the Guangxi Breeding Industry Pollution-Free Agricultural Products Origin Certification Committee.
