Fermentation bed pig-keeping litter and preparation method thereof

The invention discloses a fermentation bed pig-keeping litter. The pig-keeping litter is characterized in comprising the following biological litters, by weight: 40% of vinegar residue, 10% of sawdust, 10% of rice husk, 10% of tree bark chips, 10% of pulverized straw, 10% of bran, and 10% of clean soil. The fermentation bed pig-keeping litter has cost-reducing and process-reducing advantages. Vinegar residue and soil comprise rich microbes, such that additional inoculation is not needed. The carbon-nitrogen ratio is moderate, and is suitable for microbe growth, such that livestock and poultry manure can be converted rapidly. With the litter, no odor can be found in pigsty or chicken coop environment, and germ spreading is difficult. Livestock and poultry can be robust, and antibiotics are seldom used. Therefore, food safety is promoted. 本发明公开了种发酵床养猪垫料，其特征在于，按重量百分比计各生物垫料如下所示：醋糟40%,锯末10%、稻壳10%、树皮木屑10%、粉碎秸秆10%,麸皮10%，剩下的10%是净土。本发明的发酵床养猪垫料具有减少成本、减少工序的优点，由于醋糟、土壤中有丰富微生物，不需额外接种，碳氮比适中利于微生物生长，促进畜禽粪便迅速转化，猪舍、鸡舍环境无臭味，病菌难以
