Embodiment 1

[0032] Example 1: Acquisition of marine Rhodotorula yeast WYN1 and domestication of copper tolerance

[0033] (1) Fresh sea shrimp, starfish, seaweed and other biological samples collected from the Yellow Sea are placed in sterile YEPD medium, and red or pink round colonies are picked for further purification and culture. According to the accumulation of carotenoids in each strain, the strains with high carotenoid production were screened. Among them, the marine rhodotorula WYN1 with higher carotenoid production has oval cells without pseudohyphae; it forms red colonies on the YEPD medium prepared in seawater, with smooth surface and neat edges; it does not produce eggs on the sporulation medium Cystic spores, multilateral budding, no sporulation; no fermentation of sugar, no formation of starch-like compounds, and no inositol synthesis. Based on the above characteristics, it was preliminarily determined to belong to the genus Rhodotorula. Keep ramps in the refrigerator.

Embodiment 2

[0050] Example 2: (Comparison Test) Research on Fermentation Conditions of High-yielding Carotenoids of Rhodotorula marina WYN1

[0051] Fermentation medium composition: glucose 2.5%, peptone 2.5%, magnesium sulfate 0.02%, potassium dihydrogen phosphate 0.15%, copper content 300mg / L (copper sulfate configuration), sodium chloride 20%, the rest is water; the initial pH is 8 , the inoculum amount was 10%, the shaker speed was 180r / min, and after culturing at 28°C for 24 hours, the temperature was adjusted to 30°C, the pH was adjusted to 5, and the nitrogen source was added once, that is, peptone was added according to the addition amount of 2.5%, and continued Ferment for 24h. The marine Rhodotorula WYN1 was fermented and cultured by the above method, and its biomass, carotenoid production and intracellular copper content were 27.52 g / L, 25.12 mg / L and 6240 μg / g dry bacteria, respectively.

Embodiment 3

[0052] Embodiment 3: feed additive and its preparation

[0053] The parts by weight of the feed additive are composed as follows:

[0054] Compound polysaccharide extract 10, marine red yeast fermentation culture 15, wolfberry enzymatic hydrolysis powder 6, licorice 5, hawthorn 5, houttuynia cordata 2, dandelion 3; the complex polysaccharide extract comes from astragalus and alfalfa; the marine red yeast The deposit number is CCTCCNo: M2014592.

[0055] The preparation method of described complex polysaccharide extract is as follows:

[0056] Dry and pulverize the raw materials astragalus and alfalfa with a mass ratio of 2:1, pass through a 60-mesh sieve, add boiling water 8 times the total weight of the pulverized material, extract twice for 30 minutes each time, filter and mix the extracts, cool naturally to room temperature, and add to the extract Add absolute ethanol to the mixture to make the ethanol concentration in the mixture reach 70%, seal and refrigerate at 10°C f...

Abstract

The invention provides an efficient feed additive. The efficient feed additive is prepared from, by weight, 8-15 parts of composite polysaccharide extract, 8-20 parts of oceanic red yeast fermental culture, 5-10 parts of fructus lycii enzymolysis powder, 3-8 parts of liquorice, 3-8 parts of hawthorn, 1-5 parts of herba houttuyniae and 1-5 parts of dandelions. The composite polysaccharide extract comes from milkvetch roots and alfalfa. The conservation number of oceanic red yeast is CCTCC No:M 2014592. The oceanic red yeast can produce carotenoid with high yield and can enrich copper, the yield of carotenoid in the yeast and the content of copper in the yeast are effectively improved through a static culture method, the feed additive is used in feed, carotenoid, vitamin B and copper ions can be provided, inorganic copper ions adopted in conventional feed are well replaced through efficient copper enriching capacity, good stability is achieved, the additive and multiple kinds of Chinese herbal medicine are in compatibility, the feed additive can be adopted in feed by replacing antibiotic, the safety of animal meat products is improved, the immunity of the organisms of animals is enhanced, intestinal health is improved, the skin and hair color of the animals are improved, and the utilization rate of the feed and feeding benefits are improved.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to a high-efficiency feed additive product capable of increasing feed utilization and improving animal intestinal health and a preparation method thereof. Background technique [0002] At present, the aquaculture industry generally has problems such as low feed utilization rate, incomplete digestion of nutrients, and poor storage that lead to moisture absorption, mildew or insects in the feed. The existence of these problems not only greatly increases the cost of feeding, but also leads to waste of resources. [0003] Solving the above problems, controlling the cost of breeding, and reducing the risk of breeding are a major bottleneck for the rapid development of the breeding industry. The use of chemically synthesized additives will cause problems such as animal durability and residues, endangering human health, and there will be a large amount of excrement, such as ammoni...
