Problems solved by technology

[0002] Crop stalks are the remaining by-products of crops in food production, with large yields and low utilization rates, which is one of the difficult problems in rural areas at present.
After the crops are harvested in my country's grain-producing areas, the remaining straw is used for cooking or heating, or is stored by farmers in the form of green storage, yellow storage or ammoniation to feed livestock, and most of them are in the fields. Incineration treatment not only causes a waste of resources, but also causes serious pollution to the surrounding environment.
However, farmers have to use a large amount of grain to raise livestock every year, which not only increases the cost of farming for farmers, but also competes with people for food.

Embodiment 1

[0049] The crop straw protein feed is prepared through the following steps:

[0050] (1) Straw treatment: choose dry and mildew-free corn straw and wheat straw, and crush them to a particle size of 1.0mm-2.0mm;

[0051] (2) Ingredients: Mix the mixture, water, and inorganic salt evenly. The mixture is straw and bran, and the weight ratio is as follows:

[0052] straw:bran=7:3;

[0053] Straw: water = 1: 1.2-1.5;

[0054] Inorganic salt: 1.0%-1.5% (NH 4 ) 2 SO 4 , 0.05%-0.10% CaCl 2 , 0.10%-0.20% of K 2 HSO 4 , 0.05%-0.10% NaCl, 0.02%-0.05% MgSO 4 , the percentage is the percentage by weight of the mixture;

[0055] After mixing the above raw materials, adjust the pH to 4.8-6.0.

[0056] (3) Sterilization: The product of step (2) was sterilized by high-pressure steam sterilization, the steam pressure was 1 atm, the temperature was 121 min°C, and the sterilization time was 30 min.

[0057] (4) Vaccination:

[0058] Add strains and enzymes to the product of step (3): ...

Embodiment 2

[0073] The crop straw protein feed is prepared through the following steps:

Abstract

The invention discloses a crop straw protein feed. The crop straw protein feed is prepared by the steps of straw treatment, burdening, sterilization, inoculating, fermentation and drying. According to the invention, straws are subjected to microbial fermentation and enzymatic hydrolysis to be prepared into protein feed, so that the feeding cost can be lowered, grains can be saved, and environmental pollution caused by incineration can be reduced to provide a clean and comfortable low-carbon environment for people and the land, thus being a good project for utilizing waste materials, developing the circular economy and benefiting the nation.

Description

technical field [0001] The invention relates to a protein feed, in particular to a crop straw protein feed and a preparation method thereof. Background technique [0002] Crop straw is the remaining by-product of crops in grain production, with large yield and low utilization rate, which is one of the difficult problems in rural areas. After the crops are harvested in my country's grain-producing areas, the remaining straw is used for cooking or heating, or is stored by farmers in the form of green storage, yellow storage or ammoniation to feed livestock, and most of them are in the fields. Incineration treatment not only causes a waste of resources, but also causes serious pollution to the surrounding environment. However, farmers have to use a large amount of grain to raise livestock every year, which not only increases the breeding cost of the farmers, but also competes with people for grain. Contents of the invention [0003] The technical problem to be solved by the ...
