Preparation method of seaweed fermented feed

Abstract

The invention provides a preparation method of a seaweed fermented feed. The method comprises the following steps of: primarily washing and desalting seaweeds, and grinding to form low-salt slurry; adding brewer grain, citric acid grain, sugar residue, monopotassium phosphate, urea and viable bacteria fluid for primary fermenting salt-reduction to form primary fermentation broth; introducing rhodotorula, rhodopseudomonas palustris and sugar residue for secondary fermentation; and squeezing by a sheet frame, and quickly drying to form the seaweed fermented feed. According to the preparation method of the seaweed fermented feed, beneficial bacteria can be quickly breed after primary desalting to form a dominant bacterial community, so that the safety and absorbable nutritional value of edible seaweed can be improved, the digestion level and absorbing utilization of the feed can be improved, absorption and utilization of animals to vitamin D, copper, iron and other trace elements can be promoted, microbial community balance of water body and farmed animal intestinal tracts can be maintained, the body immunity can be enhanced, disease occurrence can be reduced, immunity of animal bodies can be enhanced, and the survival rate can be increased.

Description

technical field [0001] The invention relates to a preparation method of fermented feed, in particular to a preparation method of seaweed fermented feed. Background technique [0002] As a large agricultural and aquatic country, my country has become an important animal protein consumption product for people, and it is growing geometrically every year. With the continuous increase of people's consumption level of aquatic products, it has greatly stimulated the rapid development of my country's aquaculture industry, especially the aquaculture with seaweed as food source, such as abalone and sea cucumber. Seaweed plants are rich in nutrients and have medicinal and health functions. At the same time, seaweed plants, as important consumables, are gradually entering people's production and life, and are widely used in industries, agriculture, and medicine. [0003] Seaweed contains a variety of anti-nutritional components, such as cellulose, sugar gum, agar, xylan and other non-s...

AI Technical Summary

Problems solved by technology

[0003] Seaweed contains a variety of anti-nutritional components, such as cellulose, sugar gum, agar, xylan and other non-starch polysaccharides and their toxins; in addition, most aquatic animals that eat seaweed are lower animals with short intestines and poor digestive function These factors have greatly affected the digestion and utilization rate of seaweed, resulting in waste of resources, and also easily causing various discomforts of aquatic animals, such as enteritis, swollen mouth, etc.

In addition, due to the late start of aquaculture in our country, the system research lags behind, and the breeding technology is not perfect, it is currently in an extensive farming mode. Therefore, the feed is mostly operated by feeling or experience, resulting in serious waste of feed and loss of nutrition. Cause water environment, pool bottom corruption and other phenomena
