[0012] Embodiment 1: a kind of preparation method of selenium-enriched feed

[0013] (1) Cultivation of selenium-enriched alfalfa: In 2009, in the alfalfa production area of ​​Henan Huanghetan Hebo Grass Industry Co., Ltd. according to the aforementioned linear equation, the selenium fertilizer obtained according to the feed selenium level of 0.58mg / kg required by meat ducks Application concentration is 30mg / kg preparation anhydrous sodium selenite aqueous solution, then with 45kg / 667m 2 Spraying amount, start spraying when the alfalfa grows to a plant height of 18cm, spray once every 6 days, and spray three times in a row; spray after 4 pm, if it rains after spraying, it needs to be sprayed again; other cultivation management The measures are the same as usual;

[0014] (2) Preparation of selenium-enriched additives: harvest the alfalfa at the initial flowering stage to obtain selenium-enriched alfalfa; then dry the produced selenium-enriched alfalfa to make grass powder;

Abstract

The present invention relates to a preparation method for a selenium-enriched feedstuff, which adopts alfalfa as a carrier and is rich in organic selenium. The method comprises that: a selenium content in the selenium-enriched feedstuff is firstly determined; the concentration of applied selenium fertilizer is directly calculated according to a linear equation; then the selenium-enriched alfalfa is cultured according to the concentration of the applied selenium fertilizer; in an initial bloom stage of the alfalfa, the alfalfa is harvested and dried; then the selenium-enriched alfalfa is prepared into grass powder; the grass powder is added to a normal feedstuff according to a certain ratio, wherein the weight of the grass powder is 15% of the weight of the normal feedstuff; the treatment of mixing or pelletizing is performed to prepare a pellet feedstuff with a particle size of 2-4 mm, wherein the pellet feedstuff is the selenium-enriched feedstuff. With the selenium-enriched feedstuff, the selenium nutrition requirements of health growths of livestock and poultries are met, the immunities of livestock and poultries can be enhanced, and the livestock productivity is improved. In addition, the preparation process is simple, the cost is low and the method is easy to popularize.

Description

Technical field: [0001] The invention relates to the field of livestock and poultry feed, in particular to a method for preparing selenium-enriched feed rich in organic selenium using alfalfa as a carrier. Background technique: [0002] Selenium (Se) has triple biological functions of nutrition, toxicity and detoxification, and is called "life protection agent". Insufficient selenium content in feed not only affects the appetite of livestock and poultry, but also reduces the immunity and product quality of livestock and poultry, which can seriously cause Various diseases; while 72% of my country’s land is deficient in selenium, resulting in insufficient selenium content in animal feed; in order to meet the selenium nutritional needs of the healthy growth of livestock and poultry, while adapting to the current production needs of high efficiency, high yield, and high added value in the livestock and poultry breeding industry, We have developed selenium-enriched feed for livesto...
