The present invention discloses a feed improving egg quality produced by egg breed chickens and a preparation method thereof. The feed is prepared from the following raw materials: corn meal, rapeseed hulls, dragon fruits, shrimp bran, seaweed powder, tofu residues, fish meal, wild chrysanthemum powder, lobster shell powder, folium eucalypti powder, black soybean meal, aralia elata, and curculigo orchioides powder. Compared with the prior art, the feed has the following advantages: decocted fluid of the folium eucalypti powder and aralia elata is used to conduct treatment of the tofu residues, which effectively avoids the destruction of high temperature on soybean proteins, at the same time can also destroy anti-membrane protease, and guarantees the proteins to be fully utilized. A variety of the agricultural and sideline products are used as raw materials for the feed, which enriches the nutritional components in the feed, also expands the sources of the feed raw materials, and is conductive to reducing feed production costs. The feed is nutritionally balanced, can provide adequate nutrition for the laying chickens, ensures the egg laying rate of the laying chickens, improves the weight and quality of the produced eggs, improve the marketability of the eggs, and is obvious in economic benefits.
