Abstract

The invention relates to the technical field of biology, in particular to straw feed and preparation and application thereof. The straw feed comprises straw serving as a raw material, molasses servingas a starter initial energy source and grain feed and an enzymolysis agent serving as supplementary energy sources, a starter is capable of keeping sufficient activity, and straw cell wall polysaccharides and lignin are decomposed to generate cell wall polysaccharides which can be used by animals. Therefore, high utilizaiton degree of straw cell wall polysaccharides is realized, most of xylan canbe effectively decomposed into xylooligosaccharide in animal bodies, and an immune function is achieved; in addition, low addition quantity of molasses and grains is realized, and feed cost is reduced; further, a preparation method is simple and high in practicality.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to straw feed and its preparation and application. Background technique [0002] Corn stalks contain more than 30% carbohydrates, 2%-4% protein and 0.5%-1% fat. Sorghum stalks also contain a large amount of valuable nutrients, all of which contain a large amount of cellulose composed of linear polysaccharides. Because this type of straw pollutes the environment as fuel or solid waste, its new uses have also been widely developed. Under the influence of "circular agriculture", straw can also be used as organic fertilizer and feed. The xylan contained in straw , which can be fermented by rumen bacteria in animals to produce xylooligosaccharides that have immune effects and enhance animal disease resistance, and have broad application prospects in the field of animal feed. [0003] However, in the prior art, although straw cell wall polysaccharide content is high, its utilization rate is ...
