【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。
[Abstract]:Using fluorescent lamp as control, the growth of AA broiler was studied by using different spectral combinations of LED lamp (21% blue, 30% green, 24% yellow, 25% red yellow, 35% blue, 35% green, 18% green, 18% yellow, 12% red light), and 27% blue 30% green 22%, 21% red. Effects of slaughter performance and stress resistance. 480 1-day-old AA broilers were assigned to 4 light treatment groups with 4 repeats in each treatment. There were 30 chickens (male and female) (male and female) fed and drank freely. The light intensity was 20 lx. from the second week to the end of the experiment, the intermittent light rhythm was 14L: 4D: 2L: 4DX. The results showed that the average daily gain ratio of 1 week to 2 weeks in the B light source group was higher than that of the control group. The average daily gain of group A, C and fluorescent lamp decreased by 15.05%, 14.40% and 20.47% respectively, and the average daily gain of group B decreased by 8.62% and 9.39P0.05 respectively compared with group A and fluorescent lamp, and the average daily gain of group B showed a trend of decreasing compared with other groups. The average daily feed intake and feed weight ratio were significantly lower than and higher than those of the other three groups (P0.05), and the ratio of feed to weight at 1 ~ 6 weeks showed a tendency to increase compared with other groups. The ratio of feed to weight in group P0. 09 路C light source was significantly higher than that in group B light source (P0. 05), and the abdominal fat weight and fat bandwidth in fluorescent lamp group were significantly higher than those in group B light source. The rate of leg muscle in group B and C was significantly higher than that in group A and group B, and the value of T-AOC in group A was significantly higher than that in group A and group B, and the value of T-AOC in group C was significantly higher than that in group A and D. The results showed that the ratio of T / L in group A and group C was significantly higher than that in group A and D. Fluorescent lamps are beneficial to the performance of white broilers. From the point of view of energy saving, the balanced spectrum combination LED lamp can be used to improve the production efficiency of broilers.
