Abstract

The invention discloses a biological active padding material of a fermentation bed for poultry. The biological active padding material is prepared by the following materials in percent by weight: 15%-30% of air-permeable material, 20%-50% of water-absorbing material, 2%-20% of auxiliary nutrient material, 5%-20% of other auxiliary materials, 1%-10% of biological deodorant, 10%-30% of poultry manure and 1%-10% of fermenting bacterium agent. The biological active cushioning material disclosed by the invention has the advantages that the biological active padding material can be applied to raising of various poultry, is more reasonable in strain combination, not only has aerobic bacteria, but also has thermophilic actinomycete; simultaneously, by combination of native strains in the soil, the fermentation efficiency is improved by 30%, the bioavailability is increased by not less than 20%. The biological active cushioning material also has the advantages of wider padding material source and relative reduction of cost and the like.

Description

technical field [0001] The invention belongs to the technical field of microbes for poultry, relates to a composite microbial active litter, and also relates to a preparation method and application of the composite microbial active litter. Background technique [0002] With the intensive and large-scale development of my country's poultry industry, the incidence of poultry diseases has increased year by year, and the excretion of poultry manure has increased year by year, which have become two important problems that plague my country's aquaculture industry. In actual production, the treatment of poultry manure is limited to simple treatment methods such as drying in the sun and being used as agricultural organic fertilizer. Therefore, the treatment efficiency of poultry excrement is very low, resulting in a large amount of excrement being piled up under natural conditions. Because it contains a lot of protein and other nutrients, it will be fermented in large quantities u...
