Extruded feed for grass carps

Abstract

The invention relates to a feed, in particular to an extruded feed for grass carps. The extruded feed consists of the following substances in parts by weight: 25-35 parts of wheat, 35-45 parts of rice bran, 22-35 parts of soybean meal, 15-25 parts of cottonseed meal, 35-45 parts of rapeseed meal, 25-35 parts of peanut meal, 5-10 parts of aloe dry powder, 6-10 parts of bran, 6-10 parts of prawn powder, 1-2 parts of wintergreen oil, 1-2 parts of hymenasplenium cardiophyllum, 2-4 parts of cassava residues, 4-5 parts of fruit residues, 1-2 parts of gnetum montanum, 5-12 parts of Japanese banana leaves, 15-25 parts of soybean oil, 5-15 parts of fish meal, 15-25 parts of corn DDGS, 4-15 parts of maize germ cakes, 0.8-1.5 parts of calcium dihydrogen phosphate, 3-5 parts of xanthan gum, 2-5 parts of montmorillonite powder, 0.8-1.2 parts of methionine and 0.35-0.75 part of lysine. The extruded feed for grass carps, provided by the invention, not only meets the processing requirements of the extruded feed, but also has the characteristics of the extruded feed. When being fed in the water, the feed floats on the water level, and the extruded feed has the advantages that the feed quantity is easy to control, and the waste is reduced; and the extruded feed also has balanced nutrients, strong points, favorable food-calling properties and favorable stability, and can meet rapid growth requirements of the grass carps.

Description

technical field [0001] The invention relates to a feed, in particular to an extruded grass carp feed. Background technique [0002] Grass carp belongs to Osteostichthyes, Cyprinidae, Cyprinidae, Yaluo fish subfamily, Grass carp genus, commonly known as grass carp, grass carp, oil carp, white carp, grass root (northeast), mixed seed, etc., is a traditional freshwater aquaculture species in my country. One of the "Four Great Fish". Grass carp generally likes to inhabit the middle and lower layers of rivers, lakes and other waters and areas with many aquatic plants near the shore. They often forage in groups and are typical herbivorous fish. Grass carp is rich in nutrition, grows rapidly, has high breeding output and good economic benefits. According to the "2012 China Fishery Statistical Yearbook", the annual output of grass carp farming in my country is 4.4422 million tons, ranking first in the output of aquaculture species in the country, with an annual output value of more...

Problems solved by technology

[0003] With the gradual expansion of the scale of fish farming, high-quality fish feed has become the focus of people's research. Most of the traditional fish feed is made by rough mixing, or the ingredients are single, which not only causes water pollution, but also reduces the resistance of fish. force, reducing the breeding income
