Fermented straw, aquaculture feed composition, and preparation method and application of aquaculture feed composition

Abstract

The present invention provides fermented straw. The fermented straw is prepared by fermenting a fermenting agent for activating growth of microorganisms and crop straw powder. The fermenting agent comprises the following components in terms of the total weight of the fermenting agent and the crop straw powder: 0.02%-0.03% of cyromazine, 0.2%-0.4% of copper sulfate, 0.6%-0.8% of zinc sulfate, 0.3%-0.6% of ferrous sulfate, 0.6%-0.7% of cobalt chloride, 0.1%-0.2% of edible salt, 0.3%-0.4% of baking soda and 0.5%-1.5% of glucose powder. The present invention further provides an aquaculture feed composition. The aquaculture feed composition comprises an aquaculture feed base material and the fermented straw. The fermented straw contains a large amount of beneficial microorganisms of lactic acidbacteria, etc., and can be used as a culture water body purifying agent. The aquaculture feed composition is used as a feed, is an ecological and environment-friendly feed, and is also low in manufacturing cost.

Description

technical field [0001] The present invention relates to the technical field of microbes and aquaculture technology, in particular to a fermented straw, an aquaculture feed composition containing fermented straw, a preparation method of the aquaculture feed composition and the use of the aquaculture feed composition in aquaculture Applications. Background technique [0002] With the growth of population and the improvement of people's living standards, in order to continuously meet people's needs for food diversification and nutritional quality, the aquaculture industry has developed by leaps and bounds, and my country has become a big aquaculture country. Aquaculture needs to consume a huge amount of feed. Traditional aquaculture feed is mostly produced with grain, and there is a problem of competing with the people for food. Moreover, there are still many problems in the traditional aquaculture feed. For example, the feed nutrients are mainly starch, cellulose, and protein...

Problems solved by technology

Aquaculture needs to consume a huge amount of feed. Traditional aquaculture feed is mostly produced with grain, and there is a problem of competing with the people for food.

Moreover, there are still many problems in the traditional aquaculture feed. For example, the feed nutrients are mainly starch, cellulose, and protein, and the digestibility and nutritional value are relatively low. Farmers will add hormones, growth hormones, and fattening additives in order to increase production. etc.; the feed only provides nutrition, and cannot play the role of resisting diseases and plagues, and antibiotics need to be added in aquaculture; the feed is not fully digested, and there are more residual nutrients in aquatic feces, resulting in eutrophication of the water body

On the one hand, these problems lead to high cost of breeding and pollute the water body, on the other hand, there will be antibiotics, hormones and other additive residues in the farmed aquatic products, which will endanger the health of aquatic consumers.

These fermented straws are fermented by adding straw starters to crop straws, and the current straw starters are usually prepared from various beneficial bacteria such as actinomycetes, lactic acid bacteria, bacillus, photosynthetic bacteria, yeasts, etc., and the cost is relatively high
