摘　　要：本试验以荧光灯作为对照,研究了不同光谱组合LED灯(A(21%蓝+30%绿+24%黄+25%红)、B(35%蓝+35%绿+18%黄+12%红)、C(27%蓝+30%绿+22%黄+21%红))对AA肉鸡的生长、屠宰性能和抗应激的影响。试验选取480只1日龄AA肉鸡,平均分配到4个光照处理组,每个处理4个重复,每个重复30只鸡(公母各半),自由采食和饮水。第1周光照强度为20 lx,从第2周开始至试验结束为5 lx,间歇光照节律(14L:4D:2L:4D)。结果表明,B光源组1~2周平均日增重分别比A、C和荧光灯组显著降低了15.05%、14.40%和20.47%(P<0.05);C光源组3~5周平均日增重分别比A光源和荧光灯组降低了8.62%和9.39%(P<0.05);且B光源组1~6周平均日增重与其他组相比有减小的趋势(P=0.06)。B光源组1~2周平均日采食量和料重比显著低于和高于其他3组(P<0.05)且1~6周的料重比与其他组相比有增大的趋势(P=0.09)。C光源组3~5周料重比显著高于B光源(P<0.05)。荧光灯组腹脂重和脂带宽显著低于B和C光源组(P<0.05);C光源组腿肌率显著高于A和B光源组(P<0.05);A光源组SOD值和荧光灯组T-AOC值显著提高(P<0.05)。C光源组H:L显著高于A和D光源组(P<0.05)。研究结果显示,A光源和荧光灯均有利于白羽肉鸡生产性能的发挥,同时提高抗氧化能力,缓解肉鸡的应激反应。从节能的角度考虑,肉鸡实际生产中可采用均衡型光谱组合LED灯更有利于生产效率的提高。The aim of the present study was to investigate the effect of the different combination spectra of LED, A （21% Blue＋30% Green＋24% Yellow＋25% Red）, B （35% Blue ＋35% Green ＋18% Yellow ＋12% Red） and C （27% Blue＋30% Green ＋22% Yellow ＋21% Red）, on the growth, carcass performance and anti-stress ability of AA broilers. The fluorescent lamp was used as a control light source. A total of 480 day-old AA broilers were randomly assigned to four lighting treatments. Each treatment included 4 replicate groups with 30 chicks per group. Feed and water were provided for ad libitum. Light program was 20 lx for the first week, and 5 lx （14L： 4D： 2L： 4D） till the end （6 weeks of age）. The results showed that broilers reared under B light source had significantly decreased aver- age daily gain by 15.05%, 14.40% and 20.47% of A, C and fluorescent lamp groups at 1 to 2 weeks, respectively （P〈0.05）. C light source had significantly decreased average daily gain by 8.62% and 9.39% in A and fluorescent lamp groups at 3 to 5 weeks, respectively （P〈0.05）. B light source had a tendency to decrease average daily gain of 1 to 6 weeks （P=0.06）. B light source significantly decreased the average daily feed intake and increased feed gain ra- tio compared to other light groups at 1 to 2 weeks （P〈0.05）, and B light source had a tendency to increase feed gain ratio of 1 to 6 weeks （P=0.09）. C light source significantly increased feed gain ratio compared to B groups at 3 to 5 weeks （P〈0.05）. Abdominal fat weight and fat strip width in fluorescent lamp group were significantly lower than those in B and C groups （P〈0.05）. C light source significantly increased thigh muscle percentage compared to A and B groups （P〈0.05）. Moreover, the antioxidant carcass SOD under A light source and T-AOC under fluorescent lamp were greater than those for the other light groups （P〈0.05）. A significantly increase of H：L was observed in birds reared under C light source group
