Novel vinasse biological feed and production process thereof

Abstract

The invention discloses a novel vinasse biological feed and a production process thereof. The novel vinasse biological feed comprises a vinasse culture medium and strains, and is characterized in that a formula of the vinasse culture medium comprises the following components of: 50%-70% of fresh white spirit vinasse, 5%-15% of corn starch, 5%-15% of rapeseed dregs and 15-25% of water, wherein the percentages refer to the percentages of all the components accounting for the total weight of the vinasse culture medium, 12-18mg of ferrous sulfate, 10-15mg of zinc sulfate, 8-12mg of manganese sulfate, 12-18mg of copper sulfate and 1-3g of calcium hydrogen phosphate are added into every 80-120g of the vinasse culture medium, and the strains comprise bacillus subtilis, trichoderma viride, lactobacillus acidophilus and brettanomyces custersianus. The technological process comprises the following steps of: antagonism experiment, expanded cultivation for the strains, purity and activity inspection, preparation and sterilization for the vinasse culture medium, vinasse microbial solid fermentation and treatment for vinasse biological feed after 9-11 days. The invention has the advantages of short cycle and high protein content.

Description

technical field [0001] The invention relates to a production process for processing distiller's grains to produce novel biological feedstuffs from distiller's grains. Background technique [0002] The annual output of distiller's grains in my country is as high as more than 21 million tons. Based on the fact that distiller's grains contain certain protein, rich in amino acids, vitamins and various trace elements, etc., the traditional method is to feed fresh distiller's grains directly to livestock as feed raw materials. There are two methods for this method: There are two disadvantages: first, the crude fiber content in fresh distiller's grains is high, the palatability of livestock is poor, the digestibility is low, and moldy distiller's grains are prone to pests and diseases; second, fresh distiller's grains have high moisture content, are difficult to transport, have high acidity, and are easy to spoil. For this reason, people have carried out various studies on its resou...
