Problems solved by technology

[0002] With the rapid development of the feed industry and the high intensification of production, a large number of chemical substances are widely used as feed additives to prevent and control diseases, promote animal growth and improve the quality of animal products. The result is two problems: one is external sources The problem of residues of toxic chemicals in animal food is becoming more and more serious, which poses a great threat to human health and public health; Feces and urine enter the environment, seriously polluting the ecological environment
The disadvantages of these two methods are: the feedstuff of the first method contains inorganic selenium, which produces larger side effects on food animals.
The second method plant selenium enrichment efficiency is low and the cycle is long

Embodiment 1

[0026] The ingredients of the feed additive in this embodiment are organic selenium polysaccharides, seaweed polysaccharides, and cornstarch. The ingredients are: 0.05% organic selenium polysaccharides, 0.3% seaweed polysaccharides, and 99.65% fillers.

[0027] see figure 1 Shown, its preparation method: join 50 grams of selenium powders into 345.6 milliliters of concentrated nitric acid (concentration 65%, commercially available product), obtain selenous acid solution after dissolving completely, add 3456 milliliters of water, make solution I. The prepared solution I was added to the 30kg sodium chloride solution (0.2mol / L) that was dissolved with 1000 grams of red seaweed polysaccharide, mixed, reacted at 30°C for 20 hours, and detected the content of organic selenium polysaccharide and remaining seaweed polysaccharide, The reaction solution is mixed with cornstarch according to the weight ratio of organic selenium polysaccharide, remaining seaweed polysaccharide and cornsta...

Embodiment 2

[0035] In terms of weight percentage, the ingredients are: 0.1% organic selenium polysaccharide, 0.06% seaweed polysaccharide, and 99.84% filler.

[0036] Add 10 grams of selenium powder into 30 milliliters of concentrated nitric acid (concentration 70%, commercially available product), add 600 milliliters of water after dissolving completely to obtain selenous acid solution, and make solution I. Solution I is added in the sodium chloride solution (0.6mol / L) of 400g that is dissolved with 40 grams of fucoidan, mixes, reacts at 60 ℃ for 18 hours, detects the content of organic selenium polysaccharide and unreacted seaweed polysaccharide, will Organic selenium polysaccharides, remaining seaweed polysaccharides and corn starch are mixed according to the ratio of 1:0.6:998.4 by weight, dried, and pulverized to obtain organic selenium polysaccharide feed additives, which are packaged to produce finished products (see Figure 2-2 ).

Embodiment 3

[0043] In weight percentage, the composition is: 0.5% organic selenium polysaccharide, 1.6% seaweed polysaccharide, 97.9% filler.

[0044] 30 grams of selenium powder was added to 70 milliliters of concentrated nitric acid, and after complete dissolution, 2.1 liters of water was added to obtain a selenous acid solution, and solution I was obtained. Solution I is added in the sodium chloride solution (1.0mol / L) of 8kg that is dissolved with 360 grams of green algae polysaccharides, mixes, reacts at 80 ℃ for 12 hours, detects the content of organic selenium polysaccharides and remaining seaweed polysaccharides, organic selenium polysaccharides Polysaccharides, remaining seaweed polysaccharides and cornstarch are mixed according to the ratio of 1:3.2:195.8 by weight, dried, and pulverized to obtain organic selenium polysaccharide feed additives, which are packaged to produce finished products (see Figure 2-3 ).

Abstract

The invention relates to a non-hormone type feed additive containing organic selenium polysaccharide and preparation method thereof, belonging to the feed industry field. The preparation method comprises: adding selenium powder into concentrated nitric acid, diluting by water to obtain selenious acid solution which is called as solution I; adding the prepared solution I into sodium chloride solution dissolved with algal polysaccharides; reacting under 30-80 degrees centigrade for 12-20 hours; mixing the reaction residue- organic selenium polysaccharide and algal polysaccharides with filling material according to the weight percentages of 0.05%-0.5% of organic selenium polysaccharide, 0.06%-1.6% of algal polysaccharides and balanced amount of filling material; drying, grinding and obtaining the feed additive containing organic selenium polysaccharide. The feed additive of the invention is green, has no residue or pollution, can substitute antibiotics; also has high production efficiency, short cycle, and high selenium utilization rate, is safe and reliable for animal body without side effect.

Description

technical field [0001] The invention relates to the field of feed industry, in particular to a non-hormonal feed additive containing organic selenium polysaccharide and a preparation method thereof. Background technique [0002] With the rapid development of the feed industry and the high intensification of production, a large number of chemical substances are widely used as feed additives to prevent and control diseases, promote animal growth and improve the quality of animal products. The result is two problems: one is external sources The problem of residues of toxic chemicals in animal food is becoming more and more serious, which poses a great threat to human health and public health; Feces and urine enter the environment, seriously polluting the ecological environment. Research and development of feed additives with high-tech content is an inevitable trend of modern feed development, and it also promotes the development of feed industry and animal husbandry to a highe...
