Grass carp feed

Abstract

The invention relates to the technical field of aquaculture, and specifically relates to a grass carp feed. The feed is prepared by the following raw materials by weight: 18-20 parts of peanut bran, 35-40 parts of corn flour, 15-18 parts of fried soybean meal, 12-15 parts of rapeseed dregs, 2-3 parts of meat and bone meal, 6-8 parts of hydrilla verticillata meal, 10-12 parts of bean dregs, 10-12 parts of rice bran, 6-8 parts of fried peanut meal, 6-8 parts of pumpkin flowers, 8-10 parts of fennel tender leaves, a proper amount of salt and 4-5 parts of a phagostimulant. The prepared grass carp feed is developed from feeding habits of the grass carp. Fresh and tender plant raw materials such as the pumpkin flowers and the fennel tender leaves are added, so that palatability of the feed is improved. Meanwhile, raw materials such as the fried peanut meal and the bean dregs supplement nutrients of the basic feed. The feed is balanced in nutrition. After the feed is taken by the grass carp, the growth of the grass carp is good and survival rate is increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a grass carp feed and a preparation method thereof. Background technique [0002] Grass carp is one of the four major freshwater fishes in my country. Its tender meat and few fish bones are widely welcomed by consumers. Grass carp is resistant to rough feeding, grows rapidly, and has low breeding costs. Grass carp farming has also transitioned from traditional pond stocking to Large-scale cage farming, however, in the process of intensive farming, the feeding and management of grass carp is particularly important. Most of the existing grass carp feeds have problems such as unbalanced nutrition, excessive addition of hormone drugs, and high content of heavy metals, which cause grass carp to be prone to Nutritional diseases and drug residues have seriously affected the breeding benefits of grass carp. Therefore, in order to improve the breeding benefits, changing the feed formula...

Therefore, in order to improve the breeding benefits, changing the feed formula and ensuring nutritional balance is the most fundamental solution.
