Embodiment 1

[0014] A method for preparing beef cattle feed additives from distiller's grains, comprising the following steps:

[0015] (1) Drying: Dry the fresh corn distiller's grains to reduce the water content to 10%;

[0016] (2) Solid-state fermentation: Mix the dried corn distiller's grains with bran and corn flour at a ratio of 17:2:1, add 65% water, insert compound bacteria, and keep the temperature at 28°C-32°C and seal fermentation;

[0017] (3) Storage: Store in a sealed cellar, spread a layer of hay on the bottom and wall of the cellar, put the fermented corn distiller's grains into the cellar, and compact it while loading until the cellar is full, and cover it with non-toxic plastic film, and then compact it with soil, and wrap the cellar with non-toxic plastic film around it, and compact it with soil to ensure that it does not seep water.

[0018] In order to ensure product quality, the composite strains include rhizopus, bacillus subtilis, yeast, bifidobacterium and lacti...

Abstract

The invention discloses a method for preparing a beef cattle feed additive from distiller's grains of corn. The method comprises the following steps: drying: carrying out drying treatment on fresh distiller's grains of corn to reduce the water content to be 10 to 20 percent; carrying out solid-state fermentation: mixing the drie distiller's grains of corn, wheat bran and corn flour according to the ratio of 17 to 2 to 1; adding 60 to 65 percent of water and inoculating a compound strain; keeping the temperature at 28 to 32 DEG C and sealing and fermenting; storing: storing by adopting a sealing cellar; paving one layer of hay on a cellar bottom and a cellar wall; filling the cellar with the fermented distiller's grains of corn; filling and compacting until the cellar is fully filled with the fermented distiller's grains of corn; covering a toxin-free plastic thin film and compacting by utilizing soil; covering four sides of the cellar by utilizing the toxin-free plastic thin film; compacting and tightly pressing by utilizing the soil to ensure that water is not leaked. According to the method disclosed by the invention, the growth of mildew and spoilage bacteria can be effectivelyinhibited; the fermented distiller's grains of corn have sufficient nutrients and less alcohol content; lying-down and rumination of beef cattle are facilitated, fattening is convenient to realize andthe slaughtering time is shortened.

Description

technical field [0001] The invention belongs to the technical field of feed preparation, and in particular relates to a method for preparing beef cattle feed additives from corn distiller's grains. Background technique [0002] Compared with the developed countries in the world, my country's animal husbandry industry is far behind, and the feed industry is even more different. Due to the backwardness of the feed industry, it will inevitably restrict the development of animal husbandry. According to statistics, the world's annual output of compound feed is about 700 million tons, and fermented feed is about 25 million tons. Our country needs more than 60 million tons of feed every year, but only tens of thousands of tons of fermented feed. Although it is fermented feed, its technical level and product quality are relatively low. Therefore, it has become an inevitable trend for the development of my country's feed industry to develop new feed resources, adjust feed producti...
