Embodiment 1

[0029] The invention discloses a production method of ammoniated straw and distiller's grains mixed fermented feed. The straw is pulverized and ammoniated and then mixed with distiller's grains. The parts by weight are 70 parts of straw and 30 parts of distiller's grains. No. 1 mixed fermentation broth is cultivated, and the fermentation materials, mixed fermentation broth and water are uniformly mixed in parts by weight of 70, 5, and 25, wherein 0.03 parts of compound trace elements are dissolved in water. Put the mixed fermented materials in a well-ventilated place for fermentation, turn over once a day, and ferment for 4 days. Prepare No. 2 mixed fermentation broth, add evenly to the fermentation material according to 6% of the weight of the fermentation material, turn over the pile once a day, and ferment for 4 days. During the fermentation, water is constantly added to maintain the initial fermentation humidity. After the fermentation process is finished, the fermented m...

Embodiment 2

[0031] The invention discloses a production method of ammoniated straw and distiller's grains mixed fermented feed. The straw is pulverized and ammoniated and then mixed with distiller's grains. The parts by weight are 75 parts of straw and 25 parts of distiller's grains. No. 1 mixed fermentation broth is cultivated, and the fermentation materials, mixed fermentation broth and water are uniformly mixed in parts by weight of 65, 5, and 30, wherein 0.02 parts of compound trace elements are dissolved in water. Put the mixed fermented materials in a well-ventilated place for fermentation, turn over the pile once a day, and ferment for 3 days. Prepare No. 2 mixed fermentation bacteria liquid, add evenly to the fermentation material by 5% of the weight of the fermentation material, turn over the pile once a day, and ferment for 5 days. During the fermentation, water is constantly added to maintain the initial fermentation humidity. After the fermentation process is finished, the fe...

Embodiment 3

[0033] The invention discloses a production method of ammoniated straw and distiller's grains mixed fermented feed. The straw is crushed and ammoniated and then mixed with distiller's grains. The parts by weight are 80 parts of straw and 20 parts of distiller's grains. No. 1 mixed fermentation broth is cultivated, and the fermentation materials, mixed fermentation broth and water are uniformly mixed in 60, 5, and 35 parts by weight, wherein 0.01 part of compound trace elements is dissolved in water. Put the mixed fermented materials in a well-ventilated place for fermentation, turn over the pile once a day, and ferment for 3 days. Prepare No. 2 mixed fermentation broth, add evenly to the fermentation material by 4% of the weight of the fermentation material, turn over the pile once a day, and ferment for 5 days. During the fermentation, water is constantly added to maintain the initial fermentation humidity. After the fermentation process is finished, the fermented material i...

Abstract

The invention discloses a production method of an ammonified straw and distillers' grains mixed fermented feed, and relates to the field of environmental science. The method comprises the following steps: (1) crushing the straw and performing ammonification; (2) mixing the ammonified straw with distillers' grains; (3) preparing a No.1 mixed fermentation bacteria liquid, uniformly mixing the No.1 mixed fermentation bacteria liquid with materials, adding composite trace elements and fermenting for 3-5 days; (4) preparing a No.2 mixed fermentation bacteria liquid, uniformly mixing the No.2 mixed fermentation bacteria liquid with the fermented material and fermenting for 4-6 days; and (5) drying the fermented material containing water to obtain the straw and distillers' grains mixed feed. As the method adopts ammonified straw and adds No.1 mixed fermentation bacteria, namely efficient cellulose degradation bacteria, the cellulose degradation rate can be improved; the No.2 mixed fermentation bacteria can improve the nutrition content of the feed; and the mixed feed after fermentation contains 16-20% of crude proteins as well as multiple amino acids, has certain bouquet and acid flavor, and improves the palatability of the feed. The fermentation process is easy to operate, and the fermentation time is 7-11 days.

Description

technical field [0001] The invention relates to the field of environmental science, in particular to a method for producing ammoniated straw and distiller's grain mixed fermented feed, which is suitable for various livestock, especially ruminants. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, people's dietary structure is also gradually changing, and the proportion of meat, eggs and milk is constantly increasing. According to the statistics of relevant departments, the total output of my country's meat and eggs has ranked first in the world at present, and the per capita share has reached the world average level. For animal husbandry, the cost of feed accounts for more than 70% of the total cost, of which grain feed accounts for more than 90% of conventional feed. Therefore, with the continuous increase of people's demand for animal products, the feed gap will continue to increase...
