Problems solved by technology

[0003] However, with the market demand for protein feed, the raw materials such as beans and fish meal for the production of protein feed are scarce, and people seek to use low-cost fish waste and soybean meal to prepare protein feed, but the protein content of the prepared protein feed is low. When feeding poultry, the digestion and absorption rate is low, and the effect is not ideal

Embodiment 1

[0028] A method for preparing a protein feed obtained by mixing and fermenting fish scraps and soybean meal, comprising the following steps:

[0029] S1, the fish scraps, soybean meal and dried Tricholoma slag are respectively pulverized and passed through a 40-mesh sieve, then mixed according to a mass ratio of 2:2:1 and stirred evenly to obtain a material mixture;

[0030] The fish waste is a mixture of fish skin, fish scales, fish bones, swim bladder and fish fins;

[0031] The kind of fish that produces the leftovers of said fish is crucian carp, salmon, snakeheaded fish, hairtail;

[0032] S2. Add water to the material mixture obtained in S1 until the moisture content is 56%. Stir evenly and grab a handful tightly. Watermarks can be seen between fingers but not dripping. It is suitable to disperse when it is loosened to the ground. Spread it out and let it air for 3 hours. Then add the mixed strain culture solution to obtain the fermentation base material;

Abstract

The invention relates to the technical field of protein feed preparation, and particularly discloses a preparation method of a protein feed by mixed fermentation of fish leftovers and soybean meal. The preparation method comprises the following steps that the fish leftovers, the soybean meal and dry Tricholoma gambosum residues are respectively crushed, sieved and mixed to obtain a material mixture, after the water content is regulated, a mixed strain culture solution is added to obtain a fermentation base material, then various enzymes are added for anaerobic fermentation to obtain a fermented feed, and drying and crushing are carried out to obtain the protein feed obtained by mixed fermentation of the fish leftovers and the soybean meal. The protein content of the prepared protein feed reaches 57.24% at most, the protein feed can effectively improve the intestinal enzyme activity of poultry, and the protein digestibility of the protein feed reaches 96.42% when the protein feed is used for feeding poultry.

Description

technical field [0001] The invention relates to the technical field of protein feed preparation, in particular to a method for preparing protein feed mixed with fish leftovers and soybean meal. Background technique [0002] Protein feed refers to beans, cakes, fish meal, etc. whose natural moisture content is lower than 45%, crude fiber in dry matter is lower than 18%, and crude protein content in dry matter reaches or exceeds 20%. . Protein feed has high protein content, is rich in various amino acids, and is rich in nutrition, which is conducive to the absorption and utilization of animals. In addition, this type of feed also has a special nutritional effect, that is, it contains an unknown growth factor, which can promote animals to improve nutrition. The utilization rate of substances stimulates growth and reproduction to varying degrees and cannot be replaced by other nutrients. [0003] However, with the market demand for protein feed, the raw materials such as beans...
