Preparation method for selenium-enriched feedstuff

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...

Problems solved by technology

Although the content of inorganic selenium is high and the cost is low, the difference between the required amount and the amount of poisoning is very small, and it is very easy to be poisoned, and the application safety in production is poor.

Although organic preparations are safer and better absorbed than inorganic salts, the production process is complicated and the cost is high
