Embodiment 1

[0044] A method for microbial treatment of blasted corn stalks to produce fermented feed, comprising the following steps:

[0045] 1) Soak the air-dried corn stalks in 3 times the weight of water, and steam blast 150 g of wet corn stalks under a pressure of 1.0 MPa for 45 seconds to obtain blasting stalks;

[0046] Determination of xylose content in the blasted straw, the specific method is as follows:

[0047] (1) Drawing of xylose standard curve

[0048] Take 7 test tubes and prepare xylose standard solutions with different concentrations according to the data in the table below. Place in a boiling water bath for 10 minutes, then rapidly cool to room temperature, dilute to 25mL, and shake well. Use a 10mm colorimetric tube, preheat it in a water bath at 60°C for 5 minutes, add DNS reagent, and measure the absorbance at a wavelength of 540nm with a spectrophotometer. With the amount of glucose as the abscissa and the absorbance as the ordinate, a standard curve will be dra...

Embodiment 2

[0071] A method for microbial treatment of blasted corn stalks to produce fermented feed, comprising the following steps:

[0072] 1) Soak the air-dried corn stalks in water for 24 hours, and steam-explode 150 g of wet crop stalks for 30 s under a pressure of 0.8 MPa to obtain the blasted straws; measure the xylose content of the blasted straws according to the method of Example 1, and the result is 1.1213 ( U / mL).

[0073] Dry the obtained blasting stalks at 60° C., crush them to obtain corn stalks for fermentation, and set 3 parallels for each fermentation group.

[0074] 2) Mix the above-mentioned corn stalks for fermentation with water at a mass ratio of 1:2, then add corn steep liquor to the obtained material, the amount of corn steep liquor added is 7% of the mass of corn stalks for fermentation, and add to the obtained mixed material According to the inoculum amount of 3%, the fermented bacterial liquid was inserted, and fermented at 30° C. for 5 days to obtain ferment...

Embodiment 3

[0079] A method for microbial treatment of blasted corn stalks to produce fermented feed, comprising the following steps:

[0080] 1) The air-dried corn stalks were soaked in water for 24 hours, and 150 g of wet corn stalks were steam-exploded for 45 seconds under a pressure of 0.8 MPa to obtain the blasted straws; the xylose content of the blasted straws was measured according to the method of Example 1, and the result was 1.2148 ( U / mL).

[0081] Dry the obtained blasting stalks at 60° C., crush them to obtain corn stalks for fermentation, and set 3 parallels for each fermentation group.

[0082] 2) Mix the above-mentioned corn stalks for fermentation with water at a mass ratio of 1.5:1, then add corn steep liquor to the obtained material, the amount of corn steep liquor added is 9% of the mass of corn stalks for fermentation, and add to the obtained mixed material According to the inoculum amount of 11%, the fermented bacterial liquid was inserted, and fermented at 35° C. ...

Abstract

The invention provides a fermented feed produced by microbial treatment and explosion of crop straw and a production method and applications of the feed, and belongs to the technical field of animal-husbandry feeds. The method comprises the following steps: soaking air-dried crop straw in water for 24 hours, and carrying out steam explosion treatment on the wet crop straws at 0.8-1.0MPa for 30-60s, wherein the straw is exploded to change the original spatial structure of cellulose and to facilitate the microbial attachment; and mixing the exploded straw and water according to a mass ratio of (1-1.5):(1-2), inoculating the obtained mixture with bacillus coagulans and aspergillus oryzae, and conducting fermentation for 1-5 days at the temperature of 26-35 DEG C. The method fully degrades crude fibers in the crop straw, improves the degradation rate of the crude fibers, and is beneficial to the digestion and utilization for livestock. The prepared fermented feed is applied to the livestock breeding, and the method not only increases the way of preparing feeds by straw, but also reduces the pollution caused by the burning of the straw to the environment.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry feed, and in particular relates to a fermented feed produced by microbial treatment and blasting of crop stalks, a production method and application thereof. Background technique [0002] The animal husbandry industry has an astonishing demand for feed, and the choice of feed type directly affects the cost of breeding. Crop straw has become the first choice of feed raw materials due to its advantages of wide sources and low price. The processing of crop stalks into feed not only supports the development of animal husbandry, but also avoids improper disposal of straws due to large quantities that are difficult to handle. [0003] However, the fiber structure in crop straw is complex, and monogastric animals lack cellulase, so they cannot directly digest and utilize crop straw. Crop stalks are generally used as silage, and yellow silage generally needs to be treated with ammonia or acid a...
