Problems solved by technology

The traditional production process of fish compound feed mainly adopts the process of one-time crushing, one-time mixing and one-time granulation, but this process has the disadvantages of low maturity, poor water resistance, and low digestion and absorption.
In order to overcome this shortcoming, an improved process of secondary crushing, prolonging the conditioning time and increasing the granulation temperature is used to increase the degree of ripening. However, due to the long conditioning time and high granulation temperature of this improved process, the A lot of losses, and many substances that are not resistant to high temperature, such as enzyme preparations, beneficial active bacteria, etc. cannot be added, making the feed use effect unsatisfactory
Using this improved process has to increase the amount of vitamins in the formula, which increases the cost of feed
In addition to sinking pellet feed, there are now extruded floating fish pellet feeds. The extruded feed produced by the extruding process greatly improves the gelatinization degree of starch, but at the same time reduces the utilization rate of fish meal and soybean protein, and also causes Heat loss of vitamins and substances that are not resistant to high temperatures, and the processing cost of the puffing process is high

Abstract

The invention discloses a freshwater cyprinidae fish mixed feed composed of the following raw materials: fish meal, soybean meal, cottonseed meal, vegetable meal, flour, rice bran, soybean oil, calcium dihydrogen phosphate, compound vitamins, composite mineral elements, 50% choline chloride, zeolite powder, phytase premix, and lactobacillus premix. The preparation of the freshwater cyprinidae fish mixed feed includes two times of crushing, mixing, blending, granulating and cooling, sieving, packing and other steps. The freshwater cyprinidae fish mixed feed can increase the degree of curing of the raw materials, at the same time, improves the utilization rate of phosphorus in the feed, promotes the healthy development of fish intestinal tracts, improves feed digestion and absorption, reduces the food coefficient, and increases production and income of farmers.

Description

Technical field [0001] The invention relates to a fish compound feed formula and a preparation method thereof, in particular to a freshwater carp fish compound feed and a preparation method thereof. Background technique [0002] China is the country with the largest amount of fish compound feed in the world, reaching 15.02 million tons in 2012, of which 80% is freshwater fish compound feed, reaching 12 million tons. The traditional production process of fish compound feed mainly adopts the process of one-time crushing, one-time mixing and one-time granulation, but this process has the disadvantages of low maturity, poor water resistance, and low digestion and absorption. In order to overcome this shortcoming, an improved process of secondary crushing, prolonging the conditioning time and increasing the granulation temperature is used to increase the degree of ripening.
