Problems solved by technology

[0002] sweet sorghum (Moench) Because of its rich nutrients, high sugar content, about 14%, and fast growth, straw is mostly used as feed to directly feed livestock, but too high sugar content often easily causes excessively low acidity of animal gastric juice, which affects animal health, so Part of the straw will be burned or discarded, which on the one hand causes serious environmental pollution, and on the other hand, is also a waste of feed for China, which has a shortage of livestock feed

Embodiment 1

[0029] Embodiment 1: in the implementation example of the present invention, the yeast culture of preparation comprises the following steps:

[0030] (1) Rejuvenate the three production strains with the basic YEPD liquid medium respectively: pick a circle of slant strains and inoculate them in the seed liquid medium, the medium capacity of 150 mL Erlenmeyer flask is 50 mL, 28~30℃, Shake the flask at 180~200 r / min for 16~18 hours. This is the primary seed liquid. Put this seed liquid into the secondary seed liquid medium with an inoculum amount of 1~3%. , 28°C~30°C, 180~200 r / min shake flask culture for 16~18h; Among them, the composition of the basic YEPD liquid medium is glucose: 30~45 g / L, sucrose: 30~45 g / L, peptone: 8 ~13 g / L, (NH 4 ) 2 SO 4 : 8~13g / L, yeast extract: 18~24 g / L, KH 2 PO 4 : 0.5~1.5 g / L, MgSO 4 : 0.2~0.8 g / L,CaCl 2 : 0.1~0.5 g / L. The initial pH is 5.5; the above two media were sterilized at 115°C for 25 minutes. Among them, the inoculated bacteria ar...

Embodiment 2

[0037] Example 2 is a further example based on Example 1, and the solid addition ratio of Aspergillus niger to Aspergillus oryzae is 1:1.

Embodiment 3

[0038] Embodiment 3 is a further embodiment based on Embodiment 1, and the particle size of crushed sorghum stalks is 3 mm.

Abstract

The invention discloses a method for preparing a fermented feed through sweet sorghum straw and use of the sweet sorghum straw. The method comprises the following steps of squeezing juice from the sweet sorghum straw, performing acid treatment on straw residues, performing baking and crushing, and through an excellent liquid-phase solid-phase combined composite microbe fermented feed producing technology, preparing the fermented feed which is rich in nutrition, high in immunocompetence, good in palatability, environmentally-friendly and low in cost.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a method for fermenting feed with sweet sorghum stalks and its application. Background technique [0002] sweet sorghum (Moench) Because of its rich nutrients, high sugar content, about 14%, and fast growth, straw is mostly used as feed to directly feed livestock, but too high sugar content often easily causes excessively low acidity of animal gastric juice, which affects animal health, so Part of the straw will be burned or discarded, which on the one hand causes serious environmental pollution, and on the other hand, for China, which is short of livestock feed, it is also a waste of feed. Straw is used for feed fermentation. After being degraded by high-yield cellulase strains such as Aspergillus niger and Aspergillus oryzae, not only the nutrients of straw are fully released, but also fully absorbed and utilized by yeasts. Pollution problems can be guaranteed, the health of the gast...
