Fish feed prepared from biogas residue prepared from animal and human manure, and preparation method thereof

Abstract

The invention discloses a fish feed prepared from biogas residue prepared from animal and human manure, and a preparation method thereof. According to the preparation method, animal and human manure is subjected to biogas anaerobic fermentation; the fish feed is prepared from biogas residue obtained via biogas anaerobic fermentation, and is used for fish farming; so that environmental pollution caused by animal and human manure 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 a fish feed made from biogas residue produced from human and livestock manure and a preparation method thereof. Background technique [0002] With the growth of my country's population and the development of animal husbandry, environmental problems have become increasingly prominent, and the pollution of human and animal manure has become increasingly serious. If it is not treated harmlessly, it will further pollute the soil, water and air, and even spread pathogenic bacteria. It poses a huge threat to 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 of manure. The biogas produced by manure treated by biogas anaerobic fermentation technology can be used as energy for production and life after desulfurization treatment, and the biogas slurry...

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
