Problems solved by technology

Its advantage is that the product quality is high, but due to the use of a single strain, its conversion rate is not high, repeated separation and purification are required, and the production cost is naturally too high, so it is not suitable for the use of feed additives
CN94106402.6 discloses a method of using photosynthetic bacteria to produce selenium-enriched feed additives. Its advantage is that the production cost is low, but because the product has a single component and the application effect is not good, it is difficult to popularize and apply it in the feed industry

Embodiment Construction

[0049] The preparation method of the selenium-containing microbial feed additive of the present invention has been described in the form of an embodiment.

[0050] 1. Liquid products (take the preparation of 1000ml selenium-containing microbial liquid feed additive as an example)

[0051] A. Accurately weigh 50-60g of defatted soybean powder, soak in 500ml of water for 8-10 hours, and the soaking temperature is preferably 25-30°C. Then grind, filter, and remove slag, then add clear water to a total volume of 1000ml, sterilize by boiling (100°C), and set aside.

[0052] B. Accurately weigh 0.1gV E and V C (respectively accounting for 50%) and 0.3g ferrous sulfate, potassium iodide (respectively accounting for 80% and 20%) trace element inorganic salts and 5g sodium acetate are poured into 900ml sterilized soybean juice, and adjust the material solution with sodium selenite The selenium concentration reaches 1000ppm, and the pH value of the material is adjusted to 7-8 with Na...

Abstract

A Se-contained additive for microbial feed contains 3 kinds of living bacterial cells, active enzyme and biological Se protein, and is prepared from inorganoselenium compound, rhodopseudo-monads and nattobacillus though adding them to culture medium, liquid fermenting, adding bran, inoculating yeast, and solid fermenting.

Description

(1) Technical field [0001] The invention relates to the field of microbial feed additives for livestock and poultry, in particular to a selenium-containing microbial feed additive and a preparation method thereof. (2) Background technology [0002] Selenium is an essential trace element for humans and animals, and an important component of glutathione peroxidase in organisms. Its main function is to remove excessive free radicals produced in organisms and improve the immunity of organisms. [0003] Since American zoologists Sclzwarz and Folrz verified in 1957 that selenium is an indispensable life element for humans and animals, there have been a variety of inorganic selenium feed additives, which have played a certain role in the prevention and treatment of selenium deficiency diseases in livestock and poultry. The development of the livestock and poultry breeding industry has contributed, but with the development of modern science, its deficiencies are becoming increasingl...
