Embodiment 1

[0027] The invention discloses a method for producing fermented feed mixed with distiller's grains. Straw is pulverized and mixed with distiller's grains. The parts by weight are 75 parts of straw and 25 parts of distiller's grains. The aerobic fermentation liquid is cultivated, and the fermentation material, the mixed aerobic fermentation liquid and water are evenly mixed in parts by weight of 75, 5, and 20, wherein 0.01 part of compound trace elements is dissolved in the water. Put the mixed fermented materials in a well-ventilated place for fermentation, turn over the pile once a day, and ferment for 5 days. The anaerobic fermentation broth is prepared, and 2% of the weight of the fermentation material is evenly added to the fermentation material, and the pile is turned every two days for 4 days of fermentation. During the fermentation, water is constantly added to maintain the initial fermentation humidity. After the fermentation process is finished, the fermented materia...

Embodiment 2

[0029] The invention discloses a method for producing fermented feed mixed with distiller's grains. Straw is pulverized and mixed with distiller's grains. The parts by weight are 80 parts of straw and 20 parts of distiller's grains. The aerobic fermentation liquid is cultivated, and the fermentation material, the mixed aerobic fermentation liquid and water are uniformly mixed in parts by weight of 70, 5, and 25, wherein 0.015 parts of compound trace elements are dissolved in the water. Put the mixed fermented materials in a well-ventilated place for fermentation, turn over the pile once a day, and ferment for 5 days. The anaerobic fermentation broth is prepared, and 3% of the weight of the fermented material is evenly added to the fermented material, and the pile is turned every two days, and fermented for 4 days. During the fermentation, water is constantly added to maintain the initial fermentation humidity. After the fermentation process is finished, the fermented material...

Embodiment 3

[0031] The invention discloses a method for producing fermented feed mixed with distiller's grains. Straw is pulverized and mixed with distiller's grains. The parts by weight are 85 parts of straw and 15 parts of distiller's grains. The aerobic fermentation liquid is cultivated, and the fermentation material, the mixed aerobic fermentation liquid 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 4 days. The anaerobic fermentation liquid is prepared, and 4% of the weight of the fermented material is evenly added to the fermented material, and the heap is turned every two days, and fermented for 4 days. During the fermentation, the water is constantly replenished to maintain the initial fermentation humidity. After the fermentation process is finished, the fermented ma...

Abstract

The invention discloses straw and pot ale mixed fermented feed and a production method thereof, and relates to the field of environmental science, in particular to the mixed fermented feed and the production method thereof. The production method comprises the following steps: (1) crushing straw, and then mixing pot ale; (2) preparing aerobic fermentation bacteria liquid, uniformly spraying the aerobic fermentation bacteria liquid into materials, adding compound trace elements, and fermenting; (3) preparing anaerobic fermentation bacteria liquid, appropriately adding according to the fermentation situation of the fermented materials, and fermenting; and (4) drying the fermented materials containing water, and then getting the straw and pot ale mixed feed. Aerobic bacteria used in the method are high-efficient cellulose and lignin degrading bacteria, thereby improving the degradation rate of cellulose and lignin, fully utilizing yeast and other microbes in the pot ale to produce single-cell proteins, improving the content of nutrition in the feed, enabling the protein content to be 13-20%, having certain bouquet and acid fragrance and improving the palatability of the feed. The fermentation process is simple to operate, the fermentation time is 7-9 days, and the production time of the feed is shortened.

Description

technical field [0001] The invention relates to the field of environmental science, in particular to a mixed fermented feed and a production method thereof. 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, and the global price of grain The rise has prompted the cost of animal husbandry to rise...
