Fish feed additive capable of clearing intestine and stopping diarrhea, and preparation method thereof

Abstract

The invention discloses a fish feed additive capable of clearing intestine and stopping diarrhea, 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, traditional Chinese medicine raw materials such as the root of Chinese pulsatilla, cortex fraxini, cortex phellodendri, rhizoma coptidis, and rhizoma atractylodis macrocephalae are added, so that shigella dysenteriae is inhibited; bacteria and parasites in fish are killed; and the fish feed additive is capable of clearing intestine and stopping diarrhea, and preventing enteritis.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a fish feed additive for clearing intestines and antidiarrheal and a preparation method thereof. Background technique [0002] On the one hand, in the fish breeding process, because the fish bait is not clean or the water quality is not clean, a large number of harmful bacteria invade the fish and multiply, causing the fish to suffer from enteritis. The main symptoms of sick fish are: excretion of mucus, and occasionally the feces will adhere to the anus and appear as dragging feces; the excrement is white thin strips, and sometimes there will be abdominal swelling; when the condition is severe, the appetite will be completely lost, and the anus will be red and swollen and then bleeding. [0003] On the other hand, 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....
