Compound preparation for protecting liver and strengthening intestines in Microptenus salmoides culturing and preparation method thereof

Abstract

The invention relates to a compound preparation for protecting the liver and strengthening intestines in the Microptenus salmoides culturing and a preparation method thereof, and belongs to the technical field of aquaculture. The preparation method comprises the following steps: utilizing clostridium butyricum and lactobacillus rhamnosus to form mixed strains; fermenting the mixed strains in a solid material based on eucommia leaves, silybum marianum fruits, bran, wheat middling, rice bran, inorganic salts and the like to generate a mixed fermentation product with higher viable count; drying and crushing the fermentation product at low temperature; mixing the crushed material with glycerol monolaurate and bile acid according to a certain proportion; and performing packaging to form the compound preparation which can protect the liver of the Microptenus salmoides, improve the activity of intestinal tracts, promote digestion, inhibit pathogenic organisms and improve immunity. The preparation has the advantages of high activity, long storage life and convenient use, is directly added into a feed for feeding, protects liver and strengthens intestines through Microptenus salmoides-intestinal wall repair-intestinal microecological balance-bile acid metabolism axis, effectively removes lipid accumulation in the liver of Microptenus salmoides, repairs intestinal wall, ensures the number of beneficial bacteria in intestines, antagonizes infestation of viruses and bacteria, promotes digestion, reduces disease occurrence, and improves breeding yield and quality.

Description

technical field [0001] The invention relates to a compound preparation for protecting the liver and strengthening the intestines in California sea bass culture and a preparation method thereof, belonging to the technical field of aquaculture. Background technique [0002] California Bass ( Micropterus salmoides ), also known as largemouth bass, belongs to the order Perciformes, the family Sunfish, and the genus Perch, native to the Mississippi River system in California, USA. Because of its delicious meat, fast growth and high economic value, artificial breeding is carried out in many countries and regions. In the late 1970s, Taiwan, China was introduced from abroad, and artificial breeding was successful in 1983. In the same year, California perch was introduced to Guangdong from Taiwan, China. At present, domestic breeding areas are mainly concentrated in Huzhou, Zhejiang, Wujiang, Jiangsu, Nanhai, Shunde, Guangdong and other places. In 2017, the total output of perch f...

Although these treatment methods have certain effects, there are many hidden dangers and disadvantages

The use of antibiotics to eliminate pathogenic bacteria in the intestinal tract is a temporary solution but not a permanent cure, which will lead to problems such as antibiotic residues in tissues and drug resistance. After 2020, my country will ban the addition of antibiotics in feed

Similarly, single addition of silymarin, gl
