Compound micro-storage agent and method for preparing micro-storage straw

Abstract

The present invention relates to the technical field of forage grass material preparation and processing and biological additive applications and particularly relates to a compound micro-storage agentand a method for preparing micro-storage straw. The compound micro-storage agent comprises the following components in parts by weight: 0.15 part-0.46 part of bacillus subtilis, 0.15 part-0.35 part of enterococcus faecalis, 0.46-2.00 parts of cellulase, 1.50 parts-5.00 parts of xylanase, 70.00 parts-81.00 parts of brown sugar, 14.00 parts-16.00 parts of edible salt and 0.80 part-1.00 part of an acidifier. A formula is used to conduct the micro-storage processing of the straw. The compound micro-storage agent can improve the palatability of the straw, increases the straw intake of ruminants, can also efficiently degrade fibrous materials in the straw, thus improves the digestion and utilization efficiencies of carbohydrates, proteins and minerals in the micro-storage straw, and enables more nutrients to be used for the growth of the ruminants.

Description

technical field [0001] The invention relates to the technical field of forage preparation and processing and application of biological additives, in particular to a composite micro-storage agent and a method for preparing micro-storage straw. Background technique [0002] During the harvesting of early rice and late rice, a large amount of straw will be produced, and unprocessed straw has low nutritional value and poor palatability, which greatly limits the use of straw as a feed material for feeding ruminants such as cattle, resulting in a large amount of straw It is burned directly in the rice field, causing serious environmental pollution. The country has issued relevant laws and regulations to severely punish rice straw burning. In order to improve the feed utilization rate of rice straw and reduce the environmental pollution caused by rice straw burning, it is urgent to develop efficient and practical rice straw processing technology to improve the feeding value of rice...

Problems solved by technology

The existing technology of ammoniating rice straw with ammonia water has the following disadvantages: it is inconvenient to purchase ammonia water; ammonia water is strongly irritating and corrosive, inconvenient to use and easy to cause harm to users; residual ammonia in ammoniated rice straw can also damage ruminants eyes; the damage to the fiber structure in rice straw is very limited, and it cannot effectively improve the digestion and utilization efficiency of rice straw in the rumen

The existing urea ammonification of rice straw technology has the following disadvantages: the ammoniation effect is greatly affected by the ambient temperature, and the effect is poor when the temperature is low in winter; Digestive utilization efficiency

The existing single or compound microorganism micro-storage technology has the following disadvantages: the microorganisms cannot effectively degrade the fiber in the straw, which affects the digestion and utilization efficiency of the rice straw in the rumen; the excessive growth of spoilage bacteria is prone to occur during the micro-storage process, resulting in Unsatisfactory micro-storage effect or failure
