Abstract

The invention provides a preparation method of a fermentation state copper feed additive. The preparation method comprises the following steps: firstly preparing a fermentation substrate by taking alcohol industry yellow water, bran, powder dregs, corn flour and other industrial and agricultural side products as raw materials, then performing microbiological screening and acclimatization and culture to obtain copper-rich microorganism, inoculating to the prepared fermentation substrate and fermenting, and drying, grinding and packaging the fermented materials to obtain the fermentation state copper feed additive. Compared with the chemically synthesized copper feed additive, the fermentation state copper feed additive adopts the powder dregs, bran, alcohol industry yellow water and other side products as culture raw materials and substrates, so that the resource utilization is increased, the production cost of the copper feed additive is lowered, and the prepared fermentation state copper feed additive is more stable in bioavailability and higher in absorption rate, and the copper absorption rate is 19.2% or higher which is three times that of anhydrous copper sulfate.

Description

technical field [0001] The invention relates to the field of biological feed processing, in particular to a method for preparing a fermented copper feed additive by using microorganisms. Background technique [0002] Copper is one of the essential trace mineral elements in animals, and its content in animals is about 2~3mg / kg. Copper is mainly directly involved in the metabolism in the body as a component of metalloenzymes. In addition, copper is also involved in the absorption of iron and the formation and development of bones. Copper deficiency can cause stunted bone development, anemia, poor fur development and neurological disorders in animals. Copper deficiency in animals can lead to decreased feed intake, slowed growth, decreased feed utilization, bone abnormalities, ataxia and abnormal reproductive function. Compared with trace elements such as zinc and iron, animals have a small demand for copper, but it is still necessary to add copper preparations to meet the ne...
