Problems solved by technology

However, the existing public information uses edible fungus chaff as a raw material to prepare livestock and poultry feed using traditional technical means of adding components and solid fermentation. Some nutritional substrates are used to form solid feed. Due to the long production cycle, high processing costs, low added value of the product, the economic benefits are not significant enough.
Furthermore, the fungus chaff is used as the direct raw material to process and produce feed. Due to the high content of crude fiber and lignin in the edible fungus chaff, the palatability of the feed product is poor and the utilization rate is low, so it cannot show a good application effect.

Embodiment 1

[0046] Step (1) Dry the fresh rabbit manure with a belt-type hot air dryer at 150°C to keep the moisture content below 10%. After cooling, grind it with a universal pulverizer and pass it through a 100-mesh sieve to prepare rabbit manure powder for later use;

[0047] Step (2) Weigh 100 kg of edible fungus Pleurotus eryngii, add 1,000 kg of hot water at 40-50°C, soak for 60 minutes, heat and boil to extract for 5 hours, and then squeeze with a wrapping press to obtain a squeeze liquid. Add 500 kg of hot water at 40-50°C to the fungus chaff residue, soak for 40 minutes, heat and boil for extraction for 1.5 hours, and then squeeze it with a wrapping press to obtain a squeeze liquid, combine the two squeeze liquids; make the fungus chaff residue separately He uses;

[0048] Step (3) Centrifuge the combined squeeze liquid obtained in step (2) with a horizontal centrifuge at a centrifugal speed of 12000r / min to obtain a supernatant and a solid phase precipitate; the solid phase pre...

Embodiment 2

[0057] Step (1) Dry the fresh rabbit manure in a hot air drying oven at 200°C to keep the water content below 10%. After cooling, grind it with a universal grinder and pass it through a 100-mesh sieve to prepare rabbit manure powder for later use;

[0058] Step (2) Weigh 100 kg of edible fungus Flammulina velutipes chaff, add 500 kg of hot water at 40-50°C, soak for 50 minutes, heat and boil to extract for 4 hours, and then squeeze with a wrapping press to obtain squeezed liquid. Add 500kg of hot water at 40-50℃ to the bran residue, soak for 40 minutes, heat and boil to extract for 3 hours, and then squeeze it with a wrapping press to obtain squeezed liquid, combine the two squeezed liquids; the fungus chaff residue is used for other purposes ;

[0059] Step (3) Centrifuge the combined squeeze liquid obtained in step (2) with a horizontal centrifuge at a centrifugal speed of 8000r / min to obtain a supernatant and a solid-phase precipitate; the solid-phase precipitate is used fo...

Abstract

The invention belongs to the field of biological feed processing, and particularly discloses a preparation method of rabbit manure biological feed. The preparation method comprises the following steps: preparing slurry from rabbit manure powder and a water extraction concentrate of residue of edible mushrooms at the weight ratio of 1:(5-15), placing the slurry at the temperature of 80-90 DEG C, carrying out the Maillard reaction for 36-50 hours, adding a compound microorganism bacterium accounting for 4-8 percent by weight of the slurry, culturing and fermenting for 72-150 hours under the conditions that the temperature is 26-40 DEG C, the stirring speed is 50-180 rpm and the ventilatory capacity is 1:(0.3-1.5)V / V / min, carrying out vacuum concentration on the fermented slurry into thick paste under the conditions that the temperature is 33-36 DEG C and the pressure is -0.065-0.095 MPa, then carrying out low-temperature vacuum drying till the water content is 6-8%, smashing and screening, carrying out dry-type vertical compression pelletizing to obtain the rabbit manure biological feed. According to the preparation method, the efficient utilization of the residue of the edible mushrooms can be achieved, the application value of the rabbit manures as the feed is improved, waste resources are used to the hilt, the industrial chain is expanded, the comprehensive utilization benefits of edible mushrooms cultivation and the meat rabbit breeding industry waste are increased, the economic benefits are increased, and the ecological environment is protected.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a method for preparing rabbit manure biologically fermented feed. Background technique [0002] Rabbit farming has developed rapidly in my country in recent years, and intensive farming has gradually formed different scales in various places. Due to the low cost of raising rabbits and the research results in recent years, rabbit meat is not only rich in nutrition, but also known as beauty food. , the export volume and domestic sales of rabbit meat are increasing year by year, which undoubtedly boosts the large-scale development of my country's meat rabbit breeding industry. With the development of the rabbit industry, there is no doubt that the amount of rabbit manure produced has also accumulated and increased, which also provides abundant raw material resources for the comprehensive processing and utilization of rabbit manure. In the traditional concept, rabbit dung is a high-qua...
