Selenium-rich feed for Xiang-east black goat and application method thereof

Abstract

The invention provides a selenium-rich feed for a Xiang-east black goat. The feed comprises selenium-rich sweet potato stems and leaves, corn flour, wheat bran, sodium chloride, fish meal, bone meal, vitamin and calcium phosphate. A production method for the selenium-rich sweet potato stems and leaves comprises the following steps: sweet potato plantation: selecting a sweet potato variety, selecting a field, carrying out soil preparation and then carrying out cutting and plantation; primary folium spraying of selenium; secondary folium spraying of selenium; ternary folium spraying of selenium; and harvesting of sweet potato vines during a vigorous growing stage of sweet potato tubers, cutting of the sweet potato vines to sizes of 2 to 4 cm, drying of the cut sweet potato vines at 85 to 95 DEG C and sterilization so as to obtain the selenium-rich sweet potato stems and leaves with a selenium concentration of 800 to 1200 ppm. The invention has the beneficial effects that the selenium-rich feed can strengthen capacity of the Xiang-east black goat in resisting a variety of diseases and the immunity and antioxidation function of the Xiang-east black goat; the selenium-rich feed does not contain any hormone, is free of toxic and side effect, contains abundant dietary fiber and can remove toxin on the intestinal tracts of the Xiang-east black goat.

Description

technical field [0001] The invention relates to the field of livestock feed, and more specifically relates to a feed suitable for producing selenium-enriched Xiangdong black goats in Hunan, that is, a selenium-enriched feed for Xiangdong black goats and a use method thereof. Background technique [0002] In 1817, the Swedish chemist Berzelius discovered selenium in sulfuric acid residues, but it was not until more than 140 years later that Schwarz and Foltz discovered that selenium could prevent bait-induced liver necrosis in rats. People's understanding of selenium has undergone profound changes. Selenium and animal health relationship has received widespread attention. Botruck et al. confirmed that selenium is an essential component of glutathione peroxidase (GPx), and Yang Guangqi et al. found that selenium can prevent and treat Keshan disease, which makes people believe that "selenium is an essential micronutrient element for humans and animals." [0003] The main fun...

Problems solved by technology

[0007] There are mainly two methods for selenium-enriched animal products at home and abroad. One is subcutaneous injection of a certain concentration of inorganic selenium. Different animals have differences, and the selenium-enrichment effect is unstable, and the concentration of exogenous selenium injected is not easy to control. , the concentration is too high, causing animal hair loss or even death; the other is to directly mix high-concentration selenium in the feed with sodium selenite. Sodium selenite belongs to inorganic selenium, which is highly toxic and has great toxicity to animals. side effect
