Abstract
The fish and shrimp phagostimulant of fermented product and adsorbed protein is prepared through screening beneficial bacteria seed from cultivated animal body, culturing in composite culture medium to proliferate, concentrating and adding plant protein with phagostimulant effect. It is added into fish and shrimp feed to raise their feed intake and improve their digesting function. The production process has combined beneficial microbe fermenting technology and low temperature drying technology to ensure the fast growth of beneficial bacteria, the well preservation of metabolic product and the special cultivating function. The fish and shrimp phagostimulant is one kind of green product capable of replacing traditional phagostimulant and antioxidant.
Description
Technical field
The present invention relates to fish and shrimp phagostimulant and preparation method that a kind of tunning adhesion protein is produced, by in fish feed, adding, the peat-reek and the profitable strain that utilize microbial fermentation to produce improve aquatic livestock enteron aisle and digestive function, improve feed intake and the daily gain of animal, belong to the agro-ecology product technique field.
Background technology
Holding time for pursuing the fastest culture efficiency and improving feed in the aquaculture now, antioxidants such as a large amount of amino acid, betaine and ethoxyquinoline in feed, have been added, objectively reached the effect that improves cultured output and food calling, but make feed produce strong peculiar smell simultaneously, and betaine and antioxidant all are Chemical Manufacture at present, enrichment in culturing the fish body is for breeding production has been buried serious potential safety hazard.
At present, disclosed patent, publication number is CN92111616.0, be entitled as the mussel protein powder that Production by Microorganism Fermentation has the prawn luring function, it is as carrier with various plants albumen, animal mussel slurry is continuously fermented through two warm solids by multiple microorganism as the important protein source, produces a kind of animal protein feed.Be mainly used to do phagostimulant and the protein source of aquatic products (prawn, fish) and poultry, domestic animal (chicken, ox etc.).What it was selected for use is special high protein culture medium and fermentate, does not carry out high-temperature sterilization and microbiological indicator detection simultaneously in the sweat, and the animal safety of its production is difficult to guarantee.
Summary of the invention
The purpose of this invention is to provide fish and shrimp phagostimulant and preparation method that the tunning adhesion protein is produced, can substitute the use of betaine, antioxidant in the feed fully, the peat-reek that utilizes microbial fermentation to produce, reach the effect of food calling, adsorb special vegetable protein simultaneously, when the nutrition of breed fish body is provided, cover the peculiar smell in the feed, reach the culture efficiency of green safety.
For realizing above purpose, technical scheme of the present invention provides the fish and shrimp phagostimulant that a kind of tunning adhesion protein is produced, it is characterized in that, formulated by following percentage by weight: Lactobacillus casei 30-40%, Bifidobacterium 30-40%, false gastral cavity Candida 20-40%.
The preparation method of the fish and shrimp phagostimulant that a kind of tunning adhesion protein is produced is characterized in that, adopts fluid enlargement culture, adopts cryogenic separation and dry technology in concentration process, adds vegetable protein simultaneously in concentrating, and its preparation process is:
The first step: the separation of probiotics, purifying and preparation
A. separate: getting chyme in the crucian enteron aisle of health is the bacterium source, utilize the lactic acid bacteria culture medium to carry out strain separating, be separated to two kinds of lactic acid bacterias, the lactic acid bacteria that this product adopts has two kinds, for: Lactobacillus casei and licheniformis (13123), Bifidobacterium (Bifidobacterium ATCC7469), utilize yeast extract wort agar culture medium to separate a kind of saccharomycete in the prawn enteron aisle, the saccharomycete that the present invention adopts is maternity leave gastral cavity Candida (Candida utilis CBCC5638);
B. purifying: the Lactobacillus casei that separation is obtained adopts the lactic acid bacteria culture medium to rule, separate with licheniformis, Bifidobacterium (Bifidobacterium), and false gastral cavity Candida (Candida utilis) utilizes yeast extract wort agar culture medium to rule, separate;

The bacterial classification that the present invention adopts mainly is lactic acid bacteria and saccharomycete, normal flora has material impact to the health of its body in the cultivated animals body, microecological balance between they and host has guaranteed the eubolism of host animal, improved host's immune disease-resistance power, also abundant nutriments such as vitamin are provided simultaneously for growing of host, therefore can improve microbial population of animal intestinal tract, promote that the probiotics preparation of animal health growth is generally paid attention to, development is rapid, and it has mainly acted on:
(1) suppresses the harmful intestinal tract microorganism, after probio enters alimentary canal, a large amount of breedings, in alimentary canal, form dominant microflora, thereby suppress harmful microbe propagation, Olsson (1992) confirms can suppress Vibrio anguillarum from the isolated bacterium of turbot enteron aisle with experiment in vitro, and it has stronger adhesive capacity than Vibrio anguillarum in enteron aisle mucus;
(2) supplement the nutrients, improve organism metabolism, reduce feed coefficient, probiotics preparation itself as additive just contains a large number of nutrients, as multiple proteins, vitamin, trace element, ubiquinone etc., probio also can produce many digestive enzymeses simultaneously, assists feed digestion, improves feed efficiency;
(3) stimulating immune system improves immunity, is good immunoactivator as the probiotics preparation of feed addictive, excites immunologic function by producing the nospecific immunity regulatory factor, strengthens immunity of organisms and premunition;
(4) bacterial classification of the present invention in liquid fermentation, produce metabolism products such as the profitable strain of high concentration and enzyme, vitamin, polyphenoils enter culture the fish body after, can in fish body enteron aisle, breed rapidly, improve fish body microecological balance, improve the human body immunocompetence, realize the breed purpose of green safety.
The phagostimulant that this patent product can be used as aquiculture animal adds, its addition is 1: 800-1000, bacterial classification in this patent product all from the aquatic livestock enteron aisle seed selection cultivate and to form, for feedstuff industry 813 bulletins allow to add bacterial classification, pass through fluid enlargement culture, produce profitable strain and a large amount of metabolite of high concentration, in concentration process, adopt cryogenic separation and dry technology, profitable strain and enzyme have been guaranteed, amino acid, coenzyme, vitamin is fully preserved, in concentrating, add special vegetable protein simultaneously, nutrient protein in the palatability of raising product and the supplement feed.
The invention has the advantages that:
1. adopt beneficial microbe fermentation technique and low temperature drying technology to combine, both guaranteed the high-speed rapid growth of probiotics, guaranteed that again its metabolite keeps fully, guaranteed that to greatest extent product is to culturing the special efficacy of body;
2, used bacterial classification all screens from cultivated animals, guarantees its metabolism security.Lactic acid bacteria is cultured body enteron aisle propagation, keeps the animal body microecological balance, regulates body immunity, and saccharomycete decomposes feed, produces a large amount of single cell proteins, satisfies and cultures the bulk-growth needs;
3, the special fermenting aroma food calling that utilizes microbial fermentation and produced, fragrant odour is strong, lasting, does not need to add phagostimulant and antioxidant, has guaranteed the food security in the breeding process, has reduced aquaculture cost;
4, by adding special vegetable protein, increase the food calling effect of product, replenished the nutrient protein of feed simultaneously;
5, production process is few, and not high to equipment and technological requirement, use amount is few, is easy to promote in aquaculture.
