Problems solved by technology

[0005] Due to the physical and chemical properties of crop straw, there are many weaknesses when used in feed production, the main problem is nutritional deficiencies, such as low digestibility, poor palatability, nutritional imbalance, etc.
As a result, the food intake of livestock and poultry is low, which cannot meet the needs of milk and meat production

Abstract

The invention discloses an efficient and safe crop straw feed fermentation inoculant, a solid additive and a preparation method thereof. The preparation method includes: selecting a group of three-class nine strains of fungi, actinomycetes and bacteria which are high in functionality and combining efficiency; subjecting the strains to strain purification and rejuvenation, single-strain enlarged cultivation, mixed liquid fermentation and secondary enlarged cultivation of a concentrated mother liquid inoculant. In the preparation method, the whole preparation process is completed under the conditions of drainage and ventilation of the concentrated mother liquid inoculant in a solid straw feed semi-open fermentor. The straw feed biological solid additive after feed fermentation of various plant straws has capability of efficiently decomposing and softening straw fibers, can improve palatability, animal digestion capability and straw utilization efficiency; a microbial inoculant can degrade pesticide residue in straw and reduce infection of chemically harmful substance and becomes a substitute product of antibiotics, safety and hygiene value of using the straw to produce feed are improved, and the efficient and safe crop straw feed fermentation inoculant becomes an agroecological feed additive.

Description

technical field [0001] The invention relates to an efficient and safe fermented crop straw feed fermentation agent, in particular to a microbial additive produced from straws, and in particular to a preparation method of the efficient and safe crop straw feed fermented bacterial agent and its solid additive. Background technique [0002] An important condition for the development of animal husbandry is feed, which is nutrient-rich feed. Only good feed can increase the ratio of meat to feed. Scientific feed formula and optimized feed quality are the basis for the development of animal husbandry. Therefore, the technical core of the present invention is to treat agricultural straw with less nutritional content through microbial additives to change its weaknesses of poor palatability and low nutritional content, and improve the utilization value of the straw. This solid additive is also produced using straw. [0003] Crop stalks are the by-products left after harvesting the ma...
