Problems solved by technology

[0002] In recent years, with the improvement of living standards, people pay more attention to the quality of life. Although feed additives have greatly improved the production level of livestock and poultry, the unreasonable use of some additives has brought very bad consequences to our breeding industry. influences
The abuse of antibiotics has led to the emergence of antibiotic resistance and drug residues, which has also caused a certain degree of harm to the environment; the excessive addition of trace elements such as copper and phosphorus has caused great impact and damage to the ecological environment; organic arsenic Residues and poisoning of preparations, clenbuterol hydrochloride poisoning, etc., have seriously threatened the health of livestock, poultry and human beings; these series of problems have brought huge challenges to the healthy development of the feed industry and breeding industry

Abstract

The invention provides a germanium-rich yeast additive adopting rice bran as a medium. The additive is prepared from, by mass, 84-94% of rice bran, 0.01-0.04% of germanium dioxide and 6-16% of a yeast fermentation liquor with the inoculation amount of 8-12%. The invention also provides a preparation method of the germanium-rich yeast additive. The rice bran is used as the medium to propagate germanium-rich yeast in order to prepare the germanium-rich yeast additive. The above feed additive substantially improves the germanium absorptivity of animals and the germanium sedimentation rate in animal products, changes the quality of pork, chicken meat and eggs, improves the immunity and the anti-oxidation ability of animals, and is a novel, efficient and safe biological feed additive.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a germanium-rich yeast additive with rice bran as a medium and a preparation method thereof. Background technique [0002] In recent years, with the improvement of living standards, people pay more attention to the quality of life. Although feed additives have greatly improved the production level of livestock and poultry, the unreasonable use of some additives has brought very bad consequences to our breeding industry. influences. The abuse of antibiotics has led to the emergence of antibiotic resistance and drug residues, which has also caused a certain degree of harm to the environment; the excessive addition of trace elements such as copper and phosphorus has caused great impact and damage to the ecological environment; organic arsenic Preparation residues and poisoning, clenbuterol hydrochloride poisoning, etc., have seriously threatened the health of livestock, poultry and hu...
