Abstract
The invention relates to selenium-rich astragalus smicus feed and a production method thereof. The selenium-rich astragalus smicus feed comprises the following materials in parts by weight: 90-99 parts of selenium-rich astragalus smicus dried powder, 1-2 parts of a feed binder and 10-13 parts of water. The production method comprises the following steps: dewatering the harvested selenium-rich astragalus smicus, and making the selenium-rich astragalus smicus hay into the selenium-rich astragalus smicus dried powder with a grain diameter of 120-180 mesh through super-fine grinding; adding 1-2% of the feed binder which is formed by one of modified starch, sodium carboxymethyl celluloses and lignin or two or three of the modified starch, sodium carboxymethyl celluloses and lignin mixed at any ratio to the selenium-rich astragalus smicus dried powder, uniformly agitating by an agitator, spraying 10-13% of water while agitating, and uniformly agitating into a mixture; palletizing the mixture by an extrusion type pelletizer in an extrusion mode. The preparing method for the organic-selenium-rich feed, which is provided by the invention, has the advantages of low cost and simple technology. The feed has the advantages of high selenium content, high organic selenium ratio and the like, and the production requirement of selenium-rich products for livestock and poultry can be met.
Description
Technical field
The present invention relates to field of fodder, particularly a kind ofly take the feed producing method that is rich in Organic Selenium that Chinese milk vetch is raw material.
Background technology
Selenium is a kind of to animals and plants very important a kind of trace element all, its biological function is more and more taken seriously, approximately there is 72% area in Dan China in lacking selenium or low selenium area, at the extremely limited selenium of these region plant enrichments from soil, cannot meet animal and the people demand to selenium, thereby cause some because the disease that lacks selenium and cause is as Keshan disease, lack selenium simultaneously and also can bring out hepatonecrosis and angiocardiopathy.It is 50～250 micrograms that daily intaking amount is per capita recommended by China NI, and best channel carrys out Selenium Supplement by diet exactly.Rich selenium agricultural in China has had certain development, and such development has simultaneously driven relevant rich selenium industry, as livestock-raising, and poultry farming etc.For poultry, domestic animal provide certain Se-enriched feedstuff, not only can improve the Se content of the simultaneously all right animal products of resistance against diseases of livestock and poultry, these daily animal products are important sources that people mend selenium.
Chinese milk vetch, has another name called Chinese milk vetch, pulse family Astragalus, and Chinese milk vetch, at south China mainly as green manure and herbage use, was once brought into play this important effect in China's agricultural for a long time.Along with the use of chemical fertilizer in modern age, its cultivated area reduces in a large number.Chinese milk vetch herb can be used as medicine, and has dispelling pathogenic wind for improving eyesight, strengthening the spleen and replenishing qi, the effect of removing toxic substances pain relieving.Modern science studies confirm that Chinese milk vetch can enrichment Selenium in Soils, and then Chinese milk vetch is transported to each organ of aerial part from root absorption selenium, through the biochemical reactions of some, the inorganic selenium of absorption is converted into the high and low Organic Selenium of toxicity of bioavilability.Chinese milk vetch has again higher nutritive value, is a kind of Forage Germplasm Resources of high-quality.
The development of the rich selenium industry of China is rapid, in paddy fields in south china producing region, there is a large amount of selenium-rich rice planting areas, after rice harves, winter, most of farmland was idle, and the economic benefit in farmland fails to maximize, there is the selenium fertilizer of part to fail completely by rice in utilization simultaneously, if these selenium are fertile, be not fully utilized, will permeate the ground water or flow into other rainwash of the selenium in fertilizer, the environment of soil can severe exacerbation.
At present, the preparation method of Se-enriched feedstuff is mainly by adding some inorganic seleniums, as sodium selenite, sodium selenate and nanometer selenium, another adds some Organic Seleniums exactly, as Se-enriched yeast and natural high selenium grain dust etc., and some patents are disclosed, as CN1074343A, CN1088745A CN 103005207 A and CN 103340305 A.As CN 102318733 A, disclosed employing sprays alfalfa and produces Se-enriched feedstuff, in the time of plantation alfalfa, need to repeatedly spray, time-consuming, and Organic Selenium conversion ratio is not high, causes the waste of a large amount of selenium fertilizer, and Spraying Se-fertilizer is subject to the impact of weather.Inorganic selenium adds and in feed, to have the advantages such as the low interpolation of cost is convenient, but the toxicity of inorganic selenium is large, and livestock and poultry are had to certain potential safety hazard, but that Organic Selenium has is safe, good absorbing, but cost is higher, and technique is comparatively complicated.Therefore it is very important, developing a kind of efficient, safe Organic Selenium feed cheaply.
summary of the invention:
For addressing the above problem, the invention provides a kind of low cost, technique is simple, is rich in the feed producing method of Organic Selenium, and it is high that feed has Se content, and Organic Selenium proportion advantages of higher can meet the rich selenium product of Production of Livestock and Poultry.
The present invention is achieved by the following technical solutions:
