Chicken manure processing methods are diverse, including physical, chemical, microbial fermentation, and a combination of various techniques. Both traditional and modern methods coexist, each with its own advantages and disadvantages, and should be tailored to local conditions. The traditional method of fermenting chicken manure for fertilizer is to let it naturally pile up and ferment for 5 to 6 months, and for feed, it takes about 20 days or a month. This causes odor emissions, environmental pollution, and significant nutrient loss. In contrast, processing chicken manure with microbial fermentation not only accelerates the fermentation process, shortens the time, prevents waste, and enhances the nutritional value of chicken manure, but also dries the fermented manure through heat generated during fermentation, saving energy and reducing costs. The process is simple, easy to promote, and thus is very popular.
