Abstract

The invention provides corn gluten meal functional fermented feed and a preparation method and application thereof and belongs to the technical field of feed. The corn gluten meal functional fermented feed is a fermentation product of a culture medium containing corn gluten meal and bran under fermentation action of three bacteria. The three bacteria include bacillus subtilis and two of bacillus coagulans, thermophilic lactobacillus, bacillus natto and bear yeast. Soluble protein content in the fermented feed is increased from 3.74% to 270% at most; the novel microbial fermentation feed prepared by adding highly-symbiotic bacteria can bring about more economic benefit and has great social value. By applying the corn gluten meal functional fermented feed in animal raising, growing performance of raised animals is improved effectively while own immunity of the animals can be improved.

Description

technical field [0001] The invention belongs to the technical field of feed, in particular to corn gluten powder functional fermented feed and application thereof. Background technique [0002] With the development of my country's animal husbandry, the contradiction of protein feed shortage has become increasingly prominent. The main way to solve this contradiction is to develop new feed resources and rationally utilize existing feed resources. The production of high-protein feed by microbial fermentation is one of the effective ways to solve the shortage of feed protein resources. [0003] Corn is one of the three major food crops in the world today. In 2015, my country's corn planting area was 38,116.6 thousand hectares, with a unit yield of 5891.9Kg / ha, slightly higher than the world average. The main component of corn is starch, up to 75%, so corn plays an important role in starch production. At present, the main method of extracting corn starch in China is wet extrac...
