摘　　要： 通过对试验性热应激肉仔鸡呼吸器官、消化器官和内分泌器官的显微组织学和超微组织学观察表明:热应激时肉仔鸡的肺脏呈现充血、肺泡破裂等器质性病变;气管粘膜随热应激时间的延长完整性遭到破坏;肝脏水泡变性明显,腺胃、十二指肠、空肠和回肠的粘膜损伤、水肿。甲状腺的滤泡大小不一,滤泡细胞类型改变,肾上腺的肾间组织和嗜铬组织呈现明显的细胞变性。 The tissue samples of respiratory,digestive and endocrine organs of broilers in heat stress were continuously observed microscopic and electronmicroscopichistologically,and scanned with electron microscope.The result showed that the lung was hyperemia,congestion and hemorrhage and laryngitis tunica Nicosia was gradually destructed,and with the days going,it become severe;The liver become edema,and with the days going,the liver cells become severe hydatiddegenetation.The whole intestine tenue's tunica mucosa were destructive with the days going.Thyroid gland's follicles were not coherence in dimension and follicles cells genus changed.The adrenocortical cortex and medulla cells become severe degeneration.
