Problems solved by technology

Feeding practice has proved that feeding sows with fresh grains containing rice husks will reduce the quality of sow milk and cause diarrhea in piglets; Symptoms such as rapid heartbeat and vasoconstriction affect the normal development of pigs; in addition, distiller's grains are hot and not suitable for feeding in summer
It can be seen that although fresh distiller's grains are rich in nutrients, they are not suitable for feeding animals directly

Abstract

The invention discloses a method for producing fermented white distilled grains by using bacillus subtilis, a feed additive and application. The method includes the steps that firstly, the white distilled grains are pretreated to remove rice husks and alcohol components, and then mixed with expanded corn flour to form a fermentation medium base material; and after metal ions are added, a pH valueis adjusted by using calcium hydroxide, the medium base material is fermented by using the bacillus subtilis, and thus the feed additive is obtained. The feed additive is matched with animal diet to feed animals so that the growth rate of the animals can be improved, the immunity is enhanced, and the diarrhea rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of animal feed preparation, and in particular relates to a method for producing fermented distiller's grains by using Bacillus subtilis, a feed additive and its application. Background technique [0002] Fresh distiller's grains are the by-products of liquor produced by using grain as the main raw material and using the unique solid-state fermentation and solid-state distillation traditional winemaking process. Since the biological fermentation in the brewing process is mainly to convert the starch in the grain into alcohol, although the nutritional components and the content of the same component in distiller's grains are also different due to the different raw materials and processes used, the components are basically similar. The nutrients in distiller's grains mainly come from bacteria and their metabolic products and bacteria autolysates, except for some raw material residues left by saccharification an...
