为研究慢性湿度应激对肉仔鸡生产性能和血液生理生化指标的影响，选择生长均匀的21日龄健康A A 雄性肉仔鸡144只，随机分成3个处理，即对照（相对湿度60％）、处理1（相对湿度35％）、处理2（相对湿度85％）。试验在智能人工气候舱内进行，试验期为3周。42日龄时，测定肉仔鸡生产性能及血液生化指标。试验结果显示：与对照组相比，高湿度（85％）条件下，试验末鸡体质量、日采食量和日增体质量显著降低，料重比降低，肉仔鸡血清乳酸脱氢酶活性和谷草转氨酶活性显著升高；低湿度（35％）下，肉仔鸡生产性能降低，肉仔鸡血清谷草转氨酶活性显著升高；处理1和处理2中，肉仔鸡血清钾离子含量降低，磷、氯离子含量升高。

To study the effects of chronic humidity stress on the growth performance and blood biochemical parameters of broilers ,a total of 144 21-day-old AA male broiler chickens were allot-ted into three groups ,including the control group of 60% relative humidity (60% RH ) ,treat-ment group Ⅰ of 35% relative humidity (35% RH) and group Ⅱ of 85% relative humidity (85%RH) ,with 6 replicates per treatment and 8 birds per replicate .The experiment was conducted in the artificial climate chamber ,and the time period was 3 weeks ,from 22 to 42 days of age .By 42 days of age ,the growth performance and blood biochemical parameters were determined .The re-sults showed that compared to 60% RH ,85% RH significantly declined the finical weight ,ave-rage daily feed intake and average daily gain of broilers while the feed efficiency was only slightly declined .Birds in 35% RH had a similar trend compared with the birds in 60% RH .Compared to 60% RH ,both the 35% and 85% decreased the serum potassium contents and increased serum phosphorus and serum chlorine contents .The serum lactate dehydrogenase and aspartate ami-notransferase activities of broilers in 85% RH were higher than those in 60% RH .The serum as-partate aminotransferase activities of broilers in 35% RH were higher than those in 60% RH .
