Embodiment 1

[0011] Dry in the shade until the water content is 13.2wt% of 2000g of the fragrant inflorescence raw material, remove impurities, crush to 3-5mm, add 12L of pure aqueous solution and extract in a water bath at 80°C for 1 hour, filter the extract for solid-liquid separation, and repeat the extraction for two The second time, the waste residue was discarded, and the extracts were combined. The extract is cooled and left to settle overnight, and the precipitate is discarded. The supernatant is concentrated in vacuum and freeze-dried to obtain the Huaxiang inflorescence extract, and the tannin content is greater than 76%.

Embodiment 2

[0013] According to the addition amount of 0.5wt.%, 1.0wt.% and 2.0wt.%, the Huaxiang fruit sequence extract obtained in Example 1 was added to the commercially available grouper powder feed respectively, and after mixing evenly, fish oil and water were added to carry out Modulation (the amount of water added to the feed is to add 900-100g water for every 2.5kg feed, and add fish oil according to the 5% ratio of the feed mass fraction), adopt a twin-screw feed pelletizer to make 1.5mm hard pellet feed, carry out breeding experiments, and investigate the feed Effects of additives on growth performance of blue grouper.

[0014] Two repetitions were set up for each experimental group, and the experimental fry were randomly assigned to 8 200L rectangular blue plastic water tanks with running water, and 60 fish were stocked in each water tank, and the experimental feed was fed twice a day at 8:00 and 16:00 , every time you are full, and remove the feces in time. During the breedin...

Embodiment 3

[0019] In order to study the pathogenicity of Vibrio parahaemolyticus to blue grouper, 17 grouper were randomly selected and divided into 4 concentration groups, and each group was injected with different concentrations of bacterial solution (5 μL / g ) to determine its half-lethal concentration. The results showed that grouper injected with OD600 value of 0.17 Vibrio parahaemolyticus would not be lethal, so the group injected with 35-fold dilution was used as the control group. After 72 hours, observe and determine the median lethal concentration, that is, OD600 is about 0.6-2.0.

[0020] Add the extract of Huaxiang fruit sequence to the feed at a ratio of 0.5% to raise the blue grouper, and set up a control group (no addition group) at the same time. After the feeding experiment was over, 20 healthy blue grouper with complete body surface were taken from the two experimental groups for the challenge injection experiment of Vibrio parahaemolyticus. Resuspend Vibrio parahaemol...

Abstract

An application of a platycarya strobilacea infructescence extract. In particular, the invention provides the application of the platycarya strobilacea infructescence extract in preparation of an additive for increasing the yield of aquatic products and preventing and treating diseases of aquatic products, wherein the aquatic products includes fish or shrimp, the fish is epinepheius awoara. The platycarya strobilacea infructescence extract is a water extract of platycarya strobilacea infructescence. In the invention, the extract is prepared with water as an extraction solvent so that an extraction process is simple, economic, green, environment-friendly and safe. With the plant extract feed additive for breeding the epinepheius awoara, a growth promoting effect is achieved. A toxicity challenge test proves that the feed additive has an antibacterial capability on vibrio parahaemolyticus.

Description

technical field [0001] The invention belongs to the field of green scientific aquaculture, and in particular relates to the application of the infructome extract of the fragrant tree. Background technique [0002] At present, with the rapid development of my country's aquaculture industry, in order to improve the feed conversion rate, reduce the cost of breeding, and produce high-efficiency and low-consumption aquatic feed, the role of additives in aquatic feed has been paid more and more attention. Growth promoters, food attractants, antioxidants, immune enhancers and other drugs are usually added to the feed to achieve the effects of promoting the growth of aquatic animals, preventing and curing diseases, enhancing the body's immunity, and saving nutritional needs. However, on the one hand, these chemicals, antibiotics, hormones and other drugs and their metabolites in animals will accumulate and remain in aquatic products, endangering the health of consumers; on the other...
