Problems solved by technology

It can be seen from this that cassava stems and leaves are not excellent feed raw materials, and cassava or cassava stems and leaves are rarely used as feed raw materials in the prior art, and cassava stalks are rarely used as feed raw materials
[0006] On the other hand, the existing technologies all adopt the method of first fermentation and then expansion, such as CN106578710A and CN105795146A patents, which adopt the method of first fermentation and then expansion to prepare feed. The properties of the products after expansion are stable and can be stored for a long time. The reason for puffing as the last processing step

Embodiment 1

[0036] A method for preparing cassava whole plant bio-fermentation feed, comprising the following steps:

[0037](1) Cutting and crushing of raw materials: cutting cassava stalks and fresh cassava, cutting them to 2cm with a hay cutter, crushing pigeonpea stems and locust leaves, and passing through a 20-mesh sieve;

[0038] (2) High-temperature sterilization treatment: Put the cassava stalks that have been cut and treated in step (1) into a biodegradation tank, seal it and feed it with steam at a temperature of 120°C and a pressure of 25 MPa;

[0039] (3) Expansion cooling: the cassava stalks obtained after the steam treatment in step (2) are extruded and expanded by an extruder, and cooled to obtain dry granulation. After puffing, the drying temperature is 125°C, and the drying time is 25 minutes;

[0040] (4) Compound enzymes degrade cassava straw, fresh cassava, cassava stems and leaves, and black locust leaves:

[0041] S1 compound enzyme degrades pigeonpea stems and le...

Embodiment 2

[0047] A method for preparing cassava whole plant bio-fermentation feed, comprising the following steps:

[0048] (1) Cutting and crushing of raw materials: cutting cassava stalks and fresh cassava, cutting them to 5cm with a hay cutter, crushing pigeonpea stems and locust leaves, and passing through a 30-mesh sieve;

[0049] (2) High-temperature sterilization treatment: Put the cassava stalks that have been cut and treated in step (1) into a biodegradation tank, seal it and feed it with steam at a temperature of 120°C and a pressure of 25 MPa;

[0050] (3) Expansion cooling: the cassava stalks obtained after the steam treatment in step (2) are extruded and expanded by an extruder, and cooled to obtain dry granulation. After puffing, the drying temperature is 125°C, and the drying time is 25 minutes;

Abstract

The invention provides a whole cassava biologically fermented feed and a preparation method thereof. The cassava biologically fermented feed is obtained by using cassava, cassava stalks and / or cassava stems and leaves as feed raw materials, puffing and then fermenting. The technical scheme provided by the invention utilizes high-starch cassava and high-protein pigeonpea stems and leaves for mixed silage fermentation, and overcomes the technical prejudice that pigeonpea stems and leaves are not optimal feed materials. The invention greatly reduces some macromolecular proteins and indigestible fiber substances through the fermentation of beneficial microorganisms, reduces the fiber content, facilitates digestion and absorption of animals, improves the palatability of feed, retains the nutritional components required by animals, and also has the advantages of low feed cost, The beneficial technical effects of long storage period, alleviating the shortage of green forage grass in winter, increasing the utilization rate of cassava, pigeon pea stems and leaves and cassava stalks to reduce the discarding of cassava stalks and reducing environmental pollution.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a cassava whole plant biologically fermented feed and a preparation method thereof. Background technique [0002] In the prior art, corn is commonly used as feed raw material. However, the price of corn used in the feed industry continues to rise, and the traditional feed has high requirements for raw materials, almost to the point of communal food for humans and animals, resulting in a sharp increase in feed costs. [0003] Cassava erect shrubs, 1.5-3 m tall; tubers cylindrical. Leaves are papery, nearly round in outline, palmately parted almost to base, 3-7 lobes, oblanceolate to narrowly elliptic, apex acuminate; petiole 8-22 cm long, slightly peltate, with No obvious fine ribs. Cassava is an important food crop in many tropical and subtropical countries. It has the characteristics of easy planting, fast growth, high yield, low price and wide application. The cassava har...
