Embodiment

[0022] A nutritious and environmentally friendly fish feed additive. The weight parts (kg) of the raw materials are: crop straw 400, animal manure 50, sorghum flour 200, cicada pupa powder 150, grape seed powder 50, grass pulp 30, mango peel powder 20, Tea polyphenols 0.03, salt 2, Huoxiang 2, Atractylodes macrocephala 2, woody fragrance 1, tangerine peel 1, vegetable oil 40, sucrose ester 0.5, flavoring 0.02.

[0023] 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 extracte...

Abstract

The invention discloses a nutritional environmental-friendly fish feed additive, and a preparation method thereof. According to the preparation method, biogas anaerobic fermentation is adopted so as to change animal waste into biogas residue with utilization value; and the fish feed additive is obtained 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, traditional Chinese medicine raw materials such as agastache rugosus, rhizoma atractylodis macrocephalae, radix aucklandiae, and pericarpium citri reticulatae are added, so that the nutritional environmental-friendly fish feed additive is capable of strengthening stomach and promoting digestion, improving symptoms of fry such as less eating and anorexia, promoting growth of fry, and realizing rapid weight gain.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a nutritional and environment-friendly 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 pes...
