Glutinous red sorghum straw for feed, and preparation method thereof

Abstract

The invention provides feeding glutinous red sorghum straw and a preparation method thereof. The preparation method comprises the following steps: crushing air-dried straw, adding distilled water, sealing, and carrying out high-pressure steam sterilization to obtain straw powder; activating white rot fungi, inoculating the white rot fungi on a PDA culture medium for culturing, inoculating white rot fungi hyphae into a wheat grain culture medium, culturing in a dark place, and storing at a temperature of 3-5 DEG C after hyphae overgrow to obtain white rot fungi strains; inoculating the white rot fungi onto the straw powder, uniformly mixing, and fermenting to obtain the glutinous red sorghum straw for the feed. The invention further discloses the glutinous red sorghum straw for the feed, which is prepared by adopting the method. According to the method, the glutinous red sorghum straw is treated through the white rot fungi, the glutinous red sorghum straw fermented material which is improved in feeding value and can be directly used for feeding is obtained, the crop straw is fully utilized, straw feed development is promoted, environmental pollution is reduced, and the problems of environmental pollution, low straw utilization digestibility, low nutritional value and the like caused by straw resource waste in the prior art are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of feed preparation, and in particular relates to glutinous red sorghum straw for feeding and a preparation method thereof. Background technique [0002] As a large agricultural production country in the world, China produces a huge amount of straw resources every year, accounting for 20-30% of the world's total straw production. At present, the use of straw in my country mainly falls into the following five categories: 1. Burning as fuel to obtain energy; 2. Directly stacking in the field as bio-fertilizer (natural degradation principle); 3. As industrial raw materials such as papermaking, fiber boards, and woven handicrafts ; 4. Used as feed for animals to eat; 5. Used as a base material to replace wood chips and cottonseed husks to cultivate edible fungi, etc., which can reduce the use of wood and reduce the cost of cultivation. However, under such circumstances, at least 33% of the straw is directly disc...

Problems solved by technology

[0004] Aiming at the above-mentioned problems existing in the prior art, the present invention provides a glutinous red sorghum stalk for feeding and a preparation method thereof. The waxy red sorghum stalk is treated with white rot fungi to obtain glutinous red sorghum stalks with improved feeding value and can be directly used for feeding. Red sorghum straw fermentation material makes full use of crop straw, promotes the development of straw feed, reduces environmental pollution, and effectively solves the problems of environmental pollution caused by waste of straw resources, low digestibility of straw utilization, and low nutritional value in the prior art.
