Problems solved by technology

At present, biogas residues produced in my country are mainly used as agricultural fertilizers, but only sporadically used in breeding feed, and have not yet formed a large scale. Moreover, the biogas residues used as feed also lack fine processing, which is not conducive to animal consumption. Researching the biogas fermentation technology of manure, and processing the fermented biogas residue into animal feed for breeding is not only an important measure to protect the environment, but also a beneficial act for the benefit of farming

Embodiment

[0020] A kind of fish feed made of biogas residue produced by cow dung, the weight parts (kg) of its raw materials are: cow dung 70, corn straw 70, rape straw 60, peanut vine 60, grass 50, peanut shell 40, corn Core 40, Rapeseed Cake 300, Soy Sauce Dregs 100, Starch Dregs 100, Huakang Fermented Strain 1.7, Sanleng 3, Ophiopogon japonicus 2, Burnet 3, Rubia 2, Astragalus 2, Pork powder 40, Salt 0.5, Radish 20 , green vegetables 10, earthworm powder 30, rapeseed pollen polysaccharide 4, lobster chitin 5.

[0021] The preparation method of the rapeseed pollen polysaccharide is as follows: soak the rapeseed pollen in hot water at 90°C, treat it with an ultrasonic wave with a frequency of 20kHz for 2 hours, then use petroleum ether to reflux and degrease to remove impurities, air-dry the obtained residue, and wash it with distilled water Reflux extraction, the resulting extract was concentrated in vacuum to 1 / 5 of the original volume, precipitated with 3 times the volume of 95% eth...

Abstract

The invention discloses a fish feed prepared from biogas residue prepared from cow dung, and a preparation method thereof. According to the preparation method, cow dung is subjected to harmlessness processing; the fish feed is prepared from biogas residue obtained via biogas fermentation, and is used for fish farming; so that environmental pollution caused by cow dung is avoided, and novel feed resources and processing methods are provided for breeding industry. The fish feed is used for fish farming, and is capable of promoting absorption and utilization rate of fish on nutrients, increasing feed conversion rate, improving fish health, promoting fish growth, reducing culturing investment, and saving fund.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to fish feed made from biogas residue produced from cow dung and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the animal breeding industry, the scale of breeding is also expanding. The feces and sewage produced by breeding pose a serious threat to the living environment of the farm and nearby residents. If harmless treatment is not carried out, it will not only cause It will affect the working mood of the employees on the site, and it will also deteriorate the neighborhood relationship with nearby residents. What's more serious is that the accumulation of a large amount of feces will also breed bacteria, spread diseases, and endanger the health and life safety of people and animals. At present, the use of biogas anaerobic fermentation technology to treat manure is an effective measure to realize the harmless treatment...
