【摘要】 通过对某鸡场三种不同的纵向通风与蒸发降温设施在夏季的使用效果的观察,证明纵向通风加湿帘系统在降低鸡舍环境温度、缓解热应激、降低鸡群生产性能下降幅度等方面效果最好。纵向通风与湿墙降温系统也具有一定的效果,从性价比来讲也不失为一种好的环境控制措施。更多还原

【Abstract】 This paper describes the effect of three different vertical ventilation and evaporative cooling system in summer. The results show that vertical ventilation and wet-curtain system is the best cooling methods, vertical ventilation wet-wall system has some effects on lowing layer-house temperature, remitting heat stress and improving performance of layer flock in summer. The vertical ventilation wet-wall system is a good method of controlling environment from the cost performance.更多还原
