Abstract

The invention relates to the field of biological feeds, and particularly provides a tableted g corn fermented feed for crabs as well as a preparation method and application of the tableted corn fermented feed. The tableted corn fermented feed for crabs comprises a fermentation base material and a composite beneficial bacterium solution, wherein the fermentation base material comprises 100 parts byweight of tableted corn; the composite beneficial bacterium solution is formed by expanding propagation of a composite fermentation strain comprising bacillus subtilis, bacillus coagulans, streptococcus thermophilus, lactobacillus acidophilus, bifidobacterium, pediococcus pentosaceus, candida utilis and saccharomyces cerevisiae; the weight ratio of the composite fermentation strain to the fermentation base material is (0.25-1.0): 1000. The finished product of the tableted corn fermented feed is flaky and is more convenient for the crabs to eat. The crab feed conversion rate can be obviously improved, and the feed coefficient is further reduced; microbial structures of body surfaces and intestinal tracts of the crabs can be improved, food residues are reduced, breeding of harmful microorganisms is reduced, and the survival rate of the crabs is further increased; and the water quality can be improved, water eutrophication is prevented, and a water environment suitable for river crabs iscreated.

Description

technical field [0001] The invention relates to the field of biological feed, and specifically provides a compressed corn fermented feed for crabs and a preparation method and application thereof. Background technique [0002] The steam flaking technology mainly uses the principle of combining moist heat treatment and physical shearing to compress corn kernels into thin slices of specific thickness, so as to realize the change of protein spatial structure and the exposure of starch granules and proteins. [0003] Many reports have confirmed that flaked corn is more effective than common corn kernels in feeding ruminants. Now steam flaked corn is usually used in ruminant diet formulations, but there is no report on the application of aquaculture. [0004] With the rapid development of intensive aquaculture today, the quality and safety of freshwater aquaculture seriously restricts the development of the industry, and the destruction of the ecological environment also destroys...
