Problems solved by technology

[0003] In view of the shortcomings of traditional antibacterial drugs and antibiotics, which cause pathogenic bacteria resistance, high residue, and large dosage, more and more researchers are turning their attention to the research of antibacterial drug substitutes.
[0004] At present, there are some reports about the use of fructooligosaccharides, lactic acid bacteria, bacillus and yeast as additives in aquatic feed, but there is no report about the compatible use of these

Embodiment 1

[0021] Get 70 parts by weight of fructooligosaccharides, 13 parts by weight of lactic acid bacteria, 10 parts by weight of bacillus, and 7 parts by weight of saccharomyces; pulverize the above-mentioned components through an ultrafine pulverizer, pass through a 120-mesh sieve, and first lactic acid bacteria, bacillus, After the yeast is fully mixed in the mixer, the fructooligosaccharide is mixed with the above mixture to make an anti-stress immune enhancer.

Embodiment 2

[0023] Growth test: Eriocheir sinensis was provided by the Pukou Base of Jiangsu Freshwater Fisheries Research Institute. The healthy young crabs with basically the same size and weight were selected for the test (initial average body weight: 9.91±0.05g). Randomly divided into groups, there are control group A (feeding basal ration), control group B (adding 1.0% fructooligosaccharide in basal ration), and control group C (adding 0.2% yeast+0.2% Bacillus + 0.1% yeast) and the test group (add 0.7% of the anti-stress immune enhancer prepared in Example 1 to the basal diet), and each group set up 3 parallel experiments, with 75 test crabs in each parallel group. A total of 12 cement pools (4m×4m×2m). After 7 days of domestication, the crabs were fed with the feed of each group for 70 days, and their growth and immune indicators were measured.

[0024] Basic diet: river crab feed (crude protein 38%, crude fat 5.2%, crude fiber 6.9%, crude ash 17.8%, total phosphorus 1.2%, lysine ...

Embodiment 3

[0035]Get 65 parts by weight of fructooligosaccharides, 20 parts by weight of lactic acid bacteria, 10 parts by weight of bacillus, and 5 parts by weight of yeast; pulverize the above-mentioned components through an ultrafine pulverizer, pass through a 120-mesh sieve, and first lactic acid bacteria, bacillus, After the yeast is fully mixed in the mixer, the fructooligosaccharide is mixed with the above mixture to make an anti-stress immune enhancer.

Abstract

The invention discloses an anti-stress immunopotentiator for a Chinese mitten crab juvenile crab and a preparation method and application thereof. The method is as follows: taking fructooligosaccharides, lactic acid bacteria, Bacillus subtilis and yeast; respectively crushing the fructooligosaccharides, the lactic acid bacteria, the Bacillus subtilis and the yeast with a superfine crusher, and then sieving with a 120 mesh screen; evenly fully mixing the lactic acid bacteria, the Bacillus subtilis and the yeast in a mixer according to the proportion, and mixing the fructooligosaccharides with the lactic acid bacteria, Bacillus subtilis and yeast mixture evenly to obtain the powdery anti-stress immunopotentiator. The anti-stress immunopotentiator has the advantages of stable sources of raw materials, wide range of raw materials, simple preparation and high cost performance; the anti-stress immunopotentiator is based on the immune mechanism of crustaceans, and is helpful to improve the antioxidant capacity of crab hepatopancreas, remove free radicals in body, improve immunity and anti stress ability of the body, and promote the healthy growth of the juvenile crab when in use.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to an anti-stress immune enhancer for juvenile Chinese mitten crabs and a preparation method and application thereof. Background technique [0002] Chinese mitten crab (Eriocheir sinensis), commonly known as river crab, belongs to the phylum Arthropoda, the class Cmstacea, the order Decapoda, the family Varunidae, and the genus Eriocheir. Delicious special aquatic products have important economic value and play a pivotal role in Jiangsu's aquaculture industry. In 2015, the Jiangsu river crab breeding area reached 263.99 thousand hectares, and the output reached 364,534 tons, accounting for 45% of the national output. %. However, with the rapid development of modern aquaculture, in the process of intensive aquaculture of river crabs, first, the aquaculture water environment is deteriorating day by day; Whitening, graying, erosion, atrophy, necrosis, resulting in shriveled river crabs, wate...
