Embodiment 1

[0016] In the present embodiment, the content of premixed composite bacteria is 50 billion / gram Bacillus subtilis, 50 billion / gram Bacillus licheniformis and 50 billion / gram Bacillus cereus, and the weight percentage before compounding is Bacillus subtilis 40%, lichen Bacillus 40%, Bacillus cereus 20%. The pre-mixed composite bacteria were dissolved in a 2% sodium alginate concentration solution, the emulsification time was 20min, the stirring speed was 500r / min, the bacterial gel ratio was 1:10, and the coating was spray-dried. The total active spore content of the obtained microbial feed additive is 50 billion / g.

Embodiment 2

[0018] In this embodiment, the premixed composite bacteria are mixed with a content of 100 billion / gram Bacillus subtilis, 100 billion / gram Bacillus licheniformis and 100 billion / gram Bacillus cereus, and the weight percentage before compounding is 50% of Bacillus subtilis, Bacillus licheniformis 30%, Bacillus cereus 20%. The pre-mixed composite bacteria were dissolved in a 2.5% sodium alginate concentration solution, the emulsification time was 25 minutes, the stirring speed was 400r / min, the bacterial gel ratio was 1:12.5, and the coating was spray-dried. The total active spore content of the obtained microbial feed additive is 50 billion / g.

Abstract

The invention discloses a microbial feed additive capable of improving the meat quality of eriocheir sinensis and a preparation method thereof. The microbial feed additive comprises bacillus subtilis (Bacillus subtilis), bacillus licheniformis (Bacillus licheniformis) and bacillus cereus (Bacillus cereus). Beneficial microorganisms are utilized for degrading protein and fat an helping digestion, the conversion rate of a feed is improved, growth is promoted, the content of crude protein and crude fat of the eriocheir sinensis can be significantly improved and the content of total amino acids, essential amino acid and unsaturated fatty acid of the whole eriocheir sinensis is significantly improved.

Description

technical field [0001] The invention relates to the technical field of microbial feed additives, in particular to a microbial feed additive for improving the meat quality of Chinese mitten crabs and a preparation method thereof. Background technique [0002] In China, Chinese mitten crab is a very popular delicacy. In recent years, the artificial breeding output of hairy crab has grown rapidly year by year, becoming an important part of aquaculture economy. However, with the improvement of aquaculture intensification, the continuous abuse of antibiotics has led to environmental pollution and aggravated diseases. New antibacterial methods or substitutes need to be developed to reduce the use of antibiotics. The surface and body of humans and animals contain a large number of microorganisms with a very large number of species and complex structures, among which the number and types of intestinal bacteria are the largest. Current research has found that intestinal bacteria mai...
