Water-containing microorganism-fermented pellet feed and application thereof

Abstract

The invention discloses a water-containing microorganism-fermented pellet feed. The water-containing microorganism-fermented pellet feed is elastic pellets of which the particle size is 1-5 millimeters; and water content of the pellets is 30-50%. The water-containing microorganism-fermented pellet feed contains lactic acid bacterium, so that mold breeding can be effectively inhibited by active substances produced by fermentation of the lactic acid bacterium; and thus, shelf life of the water-containing microorganism-fermented pellet feed can be prolonged. Moreover, the lactic acid bacterium iscapable of decomposing organic matters produced by bait residues in the water, as well as degrading ammonia nitrogen and nitrites, so as to form environment beneficial for probiotic reproduction andgrowth as well as promote propagation of beneficial algae; and thus, outbreak of cyanobacteria is prevented with stability of water maintained.

Description

technical field [0001] The invention relates to the field of microbial fermented feed, in particular to a water-containing granular microbial fermented feed for aquatic animals and its application. Background technique [0002] At present, the fermented feed used in aquaculture is usually fermented by simple compounding of powdered raw materials to become aquaculture powdered fermented feed, whether it is directly fed or mixed with powdered fermented feed and conventional pellet feed into the water body to allow Aquatic animals feed, so it is difficult for aquaculture animals to feed powdery fermented feed into the intestinal tract, and it cannot play the role of fermented feed that can really improve the intestinal tract and improve the digestion and absorption rate of feed; instead, it causes more damage to the breeding water. A large burden, thus causing problems of high ammonia nitrogen and nitrite content in the aquaculture water. [0003] At present, most farmers have...

AI Technical Summary

Problems solved by technology

[0002] At present, the fermented feed used in aquaculture is usually fermented by simple compounding of powdered raw materials to become aquaculture powdered fermented feed, whether it is directly fed or mixed with powdered fermented feed and conventional pellet feed into the water body to allow Aquatic animals feed, so it is difficult for aquaculture animals to feed powdery fermented feed into the intestinal tract, and it cannot play the role of fermented feed that can really improve the intestinal tract and improve the digestion and absorption rate of feed; instead, it causes more damage to the breeding water. Large burden, thus causing problems of high ammonia nitrogen and nitrite content in aquaculture water

[0003] At present, most farmers have realized the disadvantages of powdery fermented feed and started to use granular fermented feed. However, the pelleted feed contains water and is prone to mold, resulting in a short shelf life. During transportation and storage, mold will grow and cannot be fed to aquatic products. animal food

[0004] In addition, after the current fermented feed is fed, the uneaten part of the aquatic animals remains in the aquaculture water body, resulting in eutrophication of the aquaculture water body, high nitrogen and phosphorus emissions, and serious water pollution. Aquaculture animals are susceptible to germs and the survival rate decreases

The part digested and absorbed by aquatic animals is excreted into the water body for long-term deposition, which will also cause water pollution and require frequent water changes
