Grass carp feed capable of increasing culture yield and manufacturing method thereof

Abstract

The invention discloses a grass carp feed capable of increasing the culture yield and a manufacturing method thereof. The feed is composed of the following raw materials in parts by weight: 150 to 200 parts of barley flour, 150 to 180 parts of corn flour, 120 to 150 parts of bean cake, 60 to 80 parts of corn vinasse, 40 to 60 parts of flour, 30 to 40 parts of rice bran, 30 to 40 parts of ryegrass, 20 to 30 parts of clover, 5 to 10 parts of garlic, 50 to 60 parts of wheat middling, 20 to 30 parts of bone meal, 3 to 4 parts of welsh onion, 4 to 5 parts of leek, 0.2 to 0.3 part of yeast powder, 3 to 4 parts of mint, 2 to 3 parts of stevia rebaudiana, 2 to 3 parts of hyssop, 25 to 30 parts of watermelon peel, 20 to 25 parts of hyacinth bean leaf, 10 to 15 parts of camellia, 25 to 30 parts of strawberry jam, 25 to 30 parts of sugar dreg, 20 to 25 parts of monosodium glutamate dreg, 1 to 2 parts of salt, 3 to 4 parts of sargassum thunbergii powder, 5 to 6 parts of water caltrop powder, 10 to 15 parts of phagostimulant, and a proper amount of water. The provided feed overcomes the conventional grass carp feed shortages that the components are simple, the energy is insufficient, the taste is bad, the growth of the grass carp fed by the feed is slow, the meat quality is bad, and the yield is low. The provided feed is rich in nutrients, has a good taste, can promote the growth and weight gain of grass carp, and is capable of shortening the growth period, improving the meat quality, meat taste and palatability, and increasing the yield and culture economic profit.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a grass carp feed for improving aquaculture output and a preparation method thereof. Background technique [0002] Grass carp belongs to the class of fish, Cyprinidae, Cyprinidae, and the subfamily of genus Grass carp. Commonly known as grass carp, oil carp, grass carp, white carp, grass carp, grass bract, grass root, mixed seed, etc., it is also known as the four major freshwater fish in China together with herring, bighead carp and silver carp.
