Abstract

The invention relates to organic biological feed additives containing nano selenium and zinc oxide, a preparation method and a use method. The product of the organic biological feed additives is russety dry powder with a granularity between 80 and 140 nanometers, and can form suspension with water; the selenium content is between 0.00 and 36.00 percent and the zinc content is between 0.00 and 45.00 percent; the selenium content and the zinc content can not be 0 simultaneously; the organic biological feed additives are prepared by nano selenium organic biological intermediates and nano zinc oxide organic biological intermediates which are respectively prepared by fermentation of selenium dioxide and nano zinc oxide through microorganisms in the presence of various nutrient components; and 2.3 to 11.5 mass times of water is uniformly mixed with the organic biological feed additives containing the nano selenium and the zinc oxide and then sprinkled in feed which is then used for feeding laying hens, milk cows or nanny goats for 5 to 10 days. Compared with contrast feed, the selenium content and the zinc content of produced eggs are respectively 2 to 5 times and 2 to 2.5 times; the selenium content and the zinc content of produced milk are respectively 3 to 6 times and 2 to 4 times; and the selenium content and the zinc content of produced goat milk are respectively 3 to 7 times and 3 to 6.5 times.

Example Embodiment

[0051] Example 1
[0052] Preparation of nano-selenium and zinc oxide organic biological feed additives containing 0.31% and 39.5% of selenium and zinc respectively. The ratio and quality of raw materials used in the nano-selenium organic biological intermediates and nano-zinc oxide organic biological intermediates are as follows:
[0053]
[0054] (To be continued)
[0055] (Continued from the table on the previous page)
[0056]
[0057] The preparation process is:
[0058] (1) Preparation of nano-selenium organic biological intermediates: selenium dioxide, glucose, l-lysine, methionine, cysteine, chitosan and ascorbic acid with the required raw material quality as shown in the table above are mixed in a grinder Grind for 30min, leave for 24h, then mix with sodium bicarbonate, potassium dihydrogen phosphate, manganese sulfate monohydrate, magnesium sulfate heptahydrate, calcium chloride anhydrous, ferrous sulfate heptahydrate, add water, honey, EM raw dew and mix well After sealing, reacting for 10 days under the conditions of light and 29-31°C to prepare a sweet and sour red organic biological intermediate liquid containing nano-selenium. After vacuum drying and pulverization at 65-70°C, 90 g of red dry powder was obtained, with a selenium content of 31.4%.
[0059] (2) Preparation of nano-zinc oxide organic biological intermediates: all the raw materials are stirred and mixed uniformly, then sealed, and reacted for 13 days under the conditions of light and 29-31°C to prepare a sour yellow-brown organic biological containing nano-zinc oxide Intermediate water agent. After vacuum drying and pulverization at 65-70°C, 1000 g of dry powder is obtained, with a zinc content of 39.5%.
[0060] (3) Preparation of organic biological feed additives containing nano-selenium and nano-zinc oxide: according to the mass ratio of nano-selenium organic biological intermediate dry powder and nano-zinc oxide organic biological intermediates at 1:100, take 10g of nano-selenium organic biological intermediate dry powder The dry powder of organic biological feed additive containing nano-selenium and zinc oxide is prepared by grinding with 1000g of dry powder of nano-zinc oxide organic biological intermediate for 30 minutes. The selenium content and the zinc content are 0.31% and 39.4%, respectively.
[0061] (4) Specific use and effects:
[0062] (1) Take 500g of the above additives, add 3.0Kg of water and stir it to form a liquid, spray it into 625Kg of daily feed for 5000 laying hens and mix it evenly. The selenium content and zinc content of the feed are 2.40mg/Kg and 325mg/Kg respectively. Repeat the above operation continuously for 7-12 days, the selenium content and zinc content of the laying hens were 0.415mg/Kg and 18.2mg/Kg, respectively. Respectively, laying hens fed with control feed (common feed with selenium content of 0.010~0.015mg/Kg and zinc content of 5.8~8.0mg/Kg) contained 4 times and 2 times the content of selenium and zinc in eggs.
[0063] (2) The same dosage of feed additive water as the above was sprayed into the daily concentrate feed for 40 cows and 100 goats at 600Kg and 150Kg. Repeat the above operation continuously for 5 days, the selenium content of the milk and goat milk produced are 0.021mg/Kg and 0.023mg/Kg, which are 4 times and 5 times that of the control sample; the zinc content is 3.30mg/Kg and 3.52 respectively mg/Kg is 3 times and 4.5 times of the control sample. And all comply with GB13105-91 and GB13106-91 standards.
