Problems solved by technology

At present, biogas residues produced in my country have not been popularized and effectively used in breeding feed, so the research and development of the feed value of biogas residues will not only help to realize the rational use of resources, but also help to achieve a beautiful and harmonious environment

Embodiment

[0020] An ecological fish feed additive, the weight parts (kg) of its raw materials are: crop straw 400, animal manure 50, corn flour 200, earthworm powder 150, cucumber seed powder 50, straw pulp 30, grape seed powder 20, tea poly Phenol 0.03, salt 2, cooked oil 40, food spice 0.02.

[0021] The preparation method of the tea polyphenols is as follows: Weigh a certain weight portion of fresh tea leaves, extract in a boiling water bath for 30 minutes, filter and remove the slag, add 5% salt to the obtained extract, and let it settle for 1.5 Centrifuge after 1 hour, discard the precipitate, retain the supernatant, adjust the supernatant to pH 10 with saturated lime water, let it stand for 1.5 hours, and then centrifuge, discard the supernatant, retain the precipitate, and dissolve the precipitate with 5% The citric acid was dissolved, and then extracted with ethyl acetate for 3 times, the extracts were combined, and the ethyl acetate was recovered by distillation under reduced p...

Abstract

The invention discloses an ecological fish feed additive and a preparation method thereof. According to the preparation method, animal waste is changed into biogas residue with utility value via biogas anaerobic fermentation; and the fish feed additive is prepared via further processing so as to bring benefits to cultivation and protect the environment. According to the preparation method, the biogas residue obtained via biogas fermentation is subjected to mixing granulation and particle spraying, so that nutritional ingredients are enriched, unpleasant odor is changed, palatability is improved, and feeding attraction is improved. According to the preparation method, particles obtained via granulation are subjected to grease spraying, so that floatability of the particles in water is increased, it is convenient for ingestion of fish, dissolving of the particles in water is slowed, and utilization ratio is increased. According to the preparation method, a fresh tea extract, tea polyphenol, is taken as a raw material, so that health and immunity of fish are improved, and eating of the fish cultured with the ecological fish feed additive is beneficial for appearance beautifying and skin protection, cancer prevention, sterilization, aging prevention, and radiation prevention.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an ecological fish feed additive and a preparation method thereof. Background technique [0002] With the rapid development of the animal breeding industry and the expansion of the breeding scale, the pollution of animal manure has become increasingly serious. If it is not treated harmlessly, it will further pollute the soil, water and the atmosphere, and even spread pathogenic bacteria. It poses a huge threat to the health and life safety of 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 produced can be used as energy. As a high-quality fertilizer and green pesticide used in agricultur...
