Monitoring and comparison of malodor level in henhouses

In this paper, a monitoring method for calculating the malodor level by measuring the concentration of ammonia gas and hydrogen sulfide gas in the barn is established. This method is used to monitoring the level of malodor in the traditional henhouse and that with automatic ventilation and cleaning equipment. The monitoring results showed that in the livestock and poultry production process, timely ventilation and clean up stool can effectively reduce the concentration of malodor inside the barn, and improve the livestock production environment.
