Problems solved by technology

About 600 million tons of straw (mainly rice straw, corn straw and wheat straw) are produced in my country every year, of which about 70% are consumed as living energy, less than 8% are fed to livestock after treatment, and the other part is The form of fertilizer is returned to the field, causing environmental pollution and energy loss
[0003] The digestibility of crop stalks is low, generally only 35% to 50%, and only 60% of the energy can be used by animals. The straw itself is composed of cell walls and cell contents, and the cell wall components account for about 70 to 80%. The composition is mainly composed of cellulose, hemicellulose and lignin, and the three substances are embedded together with their strong ester bonds, which hinders the degradation and utilization of cellulose and hemicellulose by rumen microorganisms

Embodiment Construction

[0008] The present invention uses bran as a carrier, and is suitable for the treatment of straw in the production of various ruminants. When using it, it should be mixed evenly with the concentrate before feeding. When storing, it should be protected from moisture and light. The suitable addition ratio is as follows:

[0009] Before treating the straw, pour the bacterial agent into 200ml water to fully dissolve it (1-2g sugar can be added if possible), and then place it at room temperature for 1-2h to revive the bacterial strain. The revived bacterial agent must be used up on the same day and cannot be used overnight. Add 3-5kg of fine cornmeal and 2kg of salt per ton of straw, stir and dissolve in water, then add straw starter, according to straw: water = 1:2, mix well and put it in a homemade plastic bag for compaction, anaerobic fermentation 3 to 4 weeks, open the bag and feed.

Abstract

The disclosed stalk processing method mainly utilizes lactic acid bacteria and saccharomycete, which has the beneficial effects of improved fodder utilization coefficient, and reduced cultivation cost.

Description

technical field [0001] The invention belongs to a combination of microbial treatment straw in the field of ruminant production. It is mainly based on lactic acid bacteria and yeast, which can quickly improve the fermentation level of straw, improve the fermentation quality and feed utilization rate, and increase the economic benefits of breeding production. Background technique [0002] Crop straw is one of the main sources of roughage for ruminants and a key unit of energy flow cycle in agro-ecosystems. About 600 million tons of straw (mainly rice straw, corn straw and wheat straw) are produced in my country every year, of which about 70% are consumed as living energy, less than 8% are fed to livestock after treatment, and the other part is The form of fertilizer is returned to the field, causing environmental pollution and energy loss. In recent years, with the continuous development of my country's animal husbandry industry, the contradiction between humans and animals c...
