| 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%(P0.05);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%(P0.05);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(P0.05)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(P0.05)。荧光灯组腹脂重和脂带宽显著低于B和C光源组(P0.05);C光源组腿肌率显著高于A和B光源组(P0.05);A光源组SOD值和荧光灯组T-AOC值显著提高(P0.05)。C光源组H:L显著高于A和D光源组(P0.05)。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。

Effects of different combinations of LED spectra on growth,carcass traits and anti-stress ability of AA broilers |

| Abstract: | 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 average 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 ratio 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 compared to A and fluorescent lamp groups (P＜0.05).In conclusion,it was concluded that A light source and fluorescent lamp were not only good for the growth performance,but also increased the antioxidant function and remit stress of AA broilers.A light source not only saved energy,but also improved the production efficiency. |
