Embodiment 1

[0018] This embodiment provides a selenium-enriched feed additive and a preparation method thereof. The selenium-enriched feed additive is a pot-bottle of dried rice chestnut powder with a selenium concentration of 1700-2500 ppm.

[0019] The method for making the above-mentioned selenium-enriched feed additive comprises: using peat soil as a substrate to transplant and cultivate potted rice chestnut plants, and after transplanting and cultivating for 2 months, irrigate the roots with sodium selenite at a concentration of 300ppm, and 20 days before bolting. One day, mix the sodium selenite of 500ppm and the gibberellin of 50ppm and then spray the crushed rice chestnut plants in pots and bottles, and dry and sterilize the mature pots and bottles of broken rice chestnut plants at 100°C, and then crush them to obtain a selenium concentration of 2000ppm Selenium-enriched pot bottle of crushed rice chestnut dry powder. It can be directly used as a feed additive.

Embodiment 2

[0021] This embodiment provides a selenium-enriched feed additive and a production method thereof. The selenium-enriched feed additive is a jug bottle of dried rice chestnut powder with a selenium concentration of 1700-2500.

[0022] The method for making the above-mentioned selenium-enriched feed additive includes: using peat soil as a substrate to transplant and cultivate potted rice chestnut plants, and after transplanting and cultivating for 2 months, irrigate the roots with sodium selenite at a concentration of 250ppm, and 20 days before bolting. After mixing 300ppm of sodium selenite and 50ppm of gibberellin, spray the broken rice chestnut plants in pots and bottles, dry and sterilize the mature pot and bottle broken rice chestnut plants at 100°C, and then pulverize them to obtain a selenium concentration of 1700 ~2500ppm selenium-enriched pot bottle crushed rice chestnut dry powder. It can be directly used as a feed additive.

Embodiment 3

[0024] This embodiment provides a selenium-enriched feed additive and a preparation method thereof. The selenium-enriched feed additive is a pot-bottle of dried rice chestnut powder with a selenium concentration of 1700-2500 ppm.

[0025] The method for making the above-mentioned selenium-enriched feed additive includes: using peat soil as a substrate to transplant and cultivate potted rice chestnut plants, and after transplanting and cultivating for 2 months, irrigating the roots with sodium selenite at a concentration of 500ppm, and 20 days before bolting. One day, after mixing the sodium selenite of 700ppm and the gibberellin of 90ppm, spray the broken rice chestnut plants in pots and bottles, dry and sterilize the mature potted rice chestnut plants at 95°C, and then pulverize them to obtain a selenium concentration of 1700 ~2500ppm selenium-enriched pot bottle crushed rice chestnut dry powder. It can be directly used as a feed additive.

Abstract

The invention relates to the field of a feed additive, particularly relates to a selenium-rich feed additive and a preparation method of the feed additive. The selenium-rich feed additive is cardamine hupingshanensis dry powder with the selenium concentration being 1700-2500ppm. The preparation method of the selenium-rich feed additive comprises the following steps of: transplanting and cultivating cardamine hupingshanensis plant with turfy soil as matrix; carrying out root-irrigation with sodium selenite with the concentration being 250-500ppm after transplanting and cultivating for two months; 20 days before bolting, mixing sodium selenite with the concentration being 300-700ppm and gibberellins with the concentration being 50-90ppm and spraying the mixture to cardamine hupingshanensis plant; and drying and sterilizing the pure cardamine hupingshanensis plant at 80-110 DEG C, then crushing to obtain selenium-rich cardamine hupingshanensis dry powder with the selenium concentration being 1700-2500ppm. The selenium-rich feed additive can enhance the ability of livestock and poultry, thereby preventing disease, improving immune ability and oxidation resistance of livestock and poultry, improving the egg yield and milk yield of animals, and prolonging the period of egg laying and milk producing products; moreover, the feed additive is safe and non-toxic.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a selenium-enriched feed additive and a preparation method thereof. Background technique [0002] Because selenium has some functions such as anti-oxidation, the use of selenium-enriched feed is becoming more and more extensive, but generally the selenium element is carried by sodium selenite and directly mixed in the feed, which belongs to inorganic selenium, but because of its large Toxins are on the verge of technology elimination. Therefore, looking for an alternative selenium-containing organic feed has become a major issue. Contents of the invention [0003] The technical problem to be solved by the present invention is the defect that the existing selenium-enriched feed has high toxicity, and a selenium-enriched feed additive is provided, which is nutritious and non-toxic. [0004] Another object of the present invention is to provide a method for preparing a selenium-enri...
