Evaluation on Air Environment of a Large Tower Type Cowshed for Dairy Cattle in Northern China
摘要
Abstract
In this study, the air environment quality indicators of a large tower type cowshed for dairy cattle in North China were monitored and evaluated at all seasons of one year, including the indicators of thermal environment, the content of ammonia (NH3), carbon dioxide (CO2), microbe and the dust in the air.The objective was to study the change rules of the mentioned indicators, to evaluate whether this type of cowshed could meet the production requirements, and to provide theoretical basis for the design and daily management of the cowshed in the Northern region of China.The results showed that all the indicators mentioned above varied with seasons and time to some extent.The wind speed inside was below the standard of dairy cattle cowshed in summer, and the temperature in 14∶00 of summer was above 27 ℃, and THI was beyond 69, so the dairy cattle suffered slight heat stress in summer.The other air environment quality indicators monitored in any time and any space all met the standard.In conclusion, the tower type cowshed monitored was suitable for dairy cattle in North China, but some facilities should be added to decrease the temperature and the heat stress in summer.关键词
