Abstract

The invention belongs to the technical field of aquaculture, and specifically discloses a feed additive for shrimps and a preparation method thereof. The feed additive for the shrimps is obtained by mixed fermentation of the following components by the mass percentage: 10-15% of photosynthetic bacteria, 20-30% of bacillus, 20-25% of yeast, 25-35% of lactic acid bacteria, 1-5% of brown sugar, 1-5%of rice bran, 0.5-1.0% of sea salt, and the balance auxiliary materials. The feed additive for the shrimps can play a role in protecting intestinal tracts of animals through microorganisms, improve the immunity of the shrimps, reduce the occurrence of diseases and improve the survival rate; the feed additive for the shrimps can improve the intestinal environment of the animals through microorganisms, increase the number of beneficial bacteria in the intestinal tracts, promote the digestion and absorption of a feed by the animals, reduce the food coefficient, promote the growth of the shrimps,improve the production performance, improves the density of shrimp seedlings, allows the shrimp meat to be fresh and sweet, have no fishy flavor and have complete shape, and can be widely used in thefield of aquaculture.

Description

technical field

[0001] The invention relates to the technical field of aquaculture, in particular to a feed additive for shrimp and a preparation method thereof. Background technique

[0002] In recent years, the aquaculture industry has paid more and more attention to the important role of microorganisms in the animal breeding process. It is well known that various microorganisms are densely arranged on the intestinal wall of healthy animals, among which more than 90% are beneficial bacteria. Due to the close arrangement of beneficial bacteria, a protective layer with a barrier effect is formed on the intestinal wall, forming a relatively stable microbial environment, so that pathogenic bacteria in the intestinal tract have no room to grow, and naturally there is no chance to infect intestinal cells. Thereby ensuring the health of the animal intestines. Therefore, maintaining the balance of intestinal microbes can make animals effectively resist the attack of harmful micr...

Examples

Embodiment 1～5

[0033] A feed additive for shrimp is obtained by mixing and fermenting the following components in a certain proportion: photosynthetic bacteria, bacillus, yeast, lactic acid bacteria, brown sugar, rice bran, sea salt and auxiliary materials. The ratio of each component is as shown in table 1:

[0034] Table 1 embodiment 1~5 the formula of feed additive for shrimp

[0035]

[0036]

[0037] The preparation method of the shrimp feed additive described in Examples 1 to 5 comprises the following steps: respectively configuring photosynthetic bacteria, bacillus, yeast and lactic acid bacteria into a bacterial suspension, and the number of effective viable bacteria in each bacterial suspension is 10 7 ~10 8cfu / mL, and then mixed in proportion to obtain a composite bacterial solution; brown sugar, rice bran, sea salt and the rest of the auxiliary materials were added to the composite bacterial solution, and fermented at 28°C, pH 6.5, and 160rpm for 25 days to obtain a feed ad...
