Problems solved by technology

In recent years, the Central No. 1 file has been encouraging the development of the biogas industry, but anaerobic biotechnology does not have the function of nitrogen and phosphorus removal and recovery, so the by-product of biogas projects—anaerobic fermentation broth can easily become a secondary pollution source. For aquaculture enterprises that do not have enough land around them, the biogas project cannot fully realize the dual purpose of pollution control and profit

Embodiment 1

[0031] The invention provides a fermented animal feces organic feed, which comprises the following components and the weight percentage of each component is:

[0032] 50 parts of animal excrement, 50 parts of dry matter, 0.1 part of enzyme, including 25 parts of potato scab, 10 parts of lactic acid bacteria casei, 10 parts of xylin acetic acid bacteria, 15 parts of Saccharomyces cerevisiae, 10 parts of Bacillus subtilis and 15 parts of bifidobacterium share.

[0033] The present invention also includes molasses with a total weight of 10-30%, and also contains trace elements and minerals.

[0034] The trace elements include one or more of copper, magnesium, zinc, iron, boron, calcium and manganese, and the content of each trace element is one thousandth of the total weight.

[0035] The minerals include one or more of calcium, chlorine, magnesium, phosphorus, potassium, sodium, and sulfur, and the content of each mineral is 1 / 1000 of the total weight.

[0036] The present inv...

Embodiment 2

[0048]Utilize the fermented organic feed of pig manure prepared in Example 1 to breed black soldier flies.

[0049] Large-scale pig farms in my country generally use nutritionally balanced diets to feed pigs. Pig manure contains a large amount of unabsorbed organic matter, minerals, and vitamins. These nutrient-rich fresh pig manures can be directly used as a feeding base for black soldier flies. Breeding black soldier flies with fresh pig manure can save production costs, and the price of pig manure is low. Since there is not enough land for manure consumption, the dry manure of many pig farms is used by surrounding farmers free of charge, and some pig farms even pay for transportation. Let the growers transport away the manure from the pig farm. In contrast, the cost of breeding black soldier flies is lower. The earthworm breeding cycle is generally 4 to 5 months, and the black soldier fly breeding cycle is mostly 32 days. The relatively short breeding cycle is conducive to ...

Abstract

The invention discloses an animal waste fermented organic feed and a preparation method thereof. The organic feed comprises the following components in parts by weight: 50 parts of animal waste, 50 parts of dried materials and 0.1 part of enzymes, wherein the enzymes comprise 25 parts of potato streptomyces scabies, 10 parts of lactobacillus casei, 10 parts of cetobacter xylinium, 15 parts of saccharomyces cerevisiae, 10 parts of bacillus subtilis and 15 parts of bifidobacterium. The organic feed contains various high-quality lactic acid bacteria, anti-nutritional factors in the feed can be effectively degraded, the nutritional value and the digestibility of the feed are improved, the feed flavor and palatability are improved, feed mildewing and aflatoxin generation are effectively prevented, the safety of the fermented feed is guaranteed, nutrient and weight losses caused by fermentation heat production and gas production are avoided, and the purposes of animal waste recycling, reduction and harmlessness can be achieved at the same time by adopting animal waste-fermented organic feed to breed hermetia illucens.

Description

technical field [0001] The invention relates to an animal manure fermented organic feed and a preparation method thereof, belonging to the technical field of microbial fermentation. Background technique [0002] With the large-scale and intensive development of my country's livestock and poultry breeding industry, the problem of manure pollution has become more and more serious, and the management of manure has become more difficult. Anaerobic biotechnology is one of the effective means of manure resource management in the aquaculture industry. It has the advantages of producing bioenergy, low demand for nitrogen and phosphorus nutrients, and good degradation ability for some organic matter. It has been widely used at present. For the treatment of farm manure. The construction of large and medium-sized biogas projects in my country shows a trend of rapid growth. It is estimated that by 2020, biogas projects will cover 84% of the existing large and medium-sized livestock far...
