Problems solved by technology

Yeast zinc is a kind of biological zinc that has been successfully developed at present, called zinc protein, but zinc can inhibit the growth of yeast and reduce the absorption and transformation of yeast to zinc. Generally, the zinc tolerance of yeast is 1 liter of yeast fermentation The liquid contains 10 grams of zinc, and it is not suitable to be added to animal feed because of the high cost

Abstract

The invention discloses a biological zinc preparation and a method for preparing the same, specifically, a zinc-rich preparation which is produced by photosynthetic bacteria is utilized, the photosynthetic bacteria use sufficient zinc resources during the fermentation process to convert inorganic zinc into organic zinc as much as possible, so the content of the organic zinc in the photosynthetic bacteria is increased, and accordingly, the biological zinc preparation with higher zinc content is prepared. The biological zinc preparation has the advantages of simple production technology, less equipment investment and easily-obtained raw materials, the prepared biological zinc preparation can be widely applied in livestock and agricultural production, and has more market competitiveness compared with yeast zinc.

Description

technical field [0001] The invention relates to a biological zinc preparation and a preparation method thereof, in particular to a zinc-rich preparation produced by photosynthetic bacteria and a preparation method thereof. The biological zinc preparation can be widely used in animal husbandry and agricultural production. Background technique [0002] Zinc is one of the essential trace elements for animals. Zinc can participate in the synthesis and metabolism of various enzymes, nucleic acids and proteins in animals. important role. If the intake of zinc in animals is insufficient, it will directly cause the decline of animal immunity, slow bone growth, and the probability of being prone to diarrhea, respiratory tract and intestinal infection and other diseases will be greatly increased. Zinc cannot be synthesized by itself in the body of animals. Enough zinc must be taken in from the outside world every day to meet the needs of various physiological functions in the body. ...
