NOVELTY - Method for treating sick or dead poultry involves (a) performing fermentation using bacteria, mixing e.g. rice bran, and crushed straw into stack, covering with stack woven cloth, turning stack, and installing into packets, (b) collecting chicken manure, expanding culture fermented microbial inoculum, and performing biochemical fermentation turning process, (c) testing pulled out dead poultry, and directly stirring to ferment matrix, continuously fermenting, and (d) completing fermentation, aging fermented mixture, and packing qualified product as organic fertilizer.    USE - The method is useful for treating sick or dead poultry (claimed), and killing harmful bacteria and viruses.    ADVANTAGE - The method is cost-effective, harmless, and environmentally-friendly, rapidly breaks down organic matter, shortens the fermentation time, and reuses resources.    DETAILED DESCRIPTION - Method for treating sick or dead poultry involves (a) performing fermentation using bacteria, uniformly mixing rice bran, crushed straw, and chicken manure in a weight ratio of 1:250:750 into conical stack, covering the stack with rubber cloth or woven cloth, allowing to stand for 20-24 hours, turning the stack once when the temperature reaches 30 degrees C, and installing the turned stack into packets, (b) collecting chicken manure in step (a), expanding culture fermented microbial inoculum based on mixing ratio of 5 kg/m3, and performing biochemical fermentation turning process for fermenting dead poultry in fermentation matrix, (c) pulling out the dead poultry, dissecting and testing the pulled out dead poultry, directly stirring to ferment matrix during fermentation process, where after testing the dead poultry the dead poultry is crushed using crushing device at high speed, continuously fermenting, preventing anaerobic conditions, and maintaining fermentation temperature at 60 degrees C for more than 22-26 days, and (d) completing fermentation process, aging the fermented mixture for 14-16 days after index detection, and packing qualified product as organic fertilizer.
