摘要:

本试验采用定制的LED灯作为人工光源,研究4种不同光谱比例组合LED光源(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)和D(42%蓝+28%绿+18%黄+12%红))对AA肉鸡的生长、免疫力、屠宰性能和福利的影响,以确定适合白羽肉鸡养殖的最适光谱组合。试验选取600只1日龄AA肉鸡,平均分配到4个不同光谱组合处理中,每个处理5个重复,每个重复30只鸡(公母各半),自由采食和饮水。第一周光照强度为20 lx,从第二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,C光源4~6周平均日增重比A、B和D光源组分别显著降低14.45%、13.76%和12.91%(P<0.05),且1~6周平均日增重与其他组相比有减小的趋势(P=0.07)。与D光源组相比,C光源组显著降低4~6周和1~6周平均日采食量(P<0.05);A光源组4~6周料重比比D光源组显著降低9.14%(P<0.05);D光源新城疫(NDV)和禽流感(Re-6)抗体效价显著低于其他组(P<0.05),与B光源比较,A、C和D 光源组步态评分值均显著降低(分别为44.97%、26.32%和33.33%,P<0.05)。眼球发育和屠宰性能不受光谱组合的影响(P>0.05)。研究结果显示,A光源更有利于白羽肉鸡生产性能的发挥,同时提高肉鸡的免疫功能和福利水平。

Abstract:

This experiment was conducted to investigate the effects of 4 LED spectral combination (named: A (21% Blue+30% Green+24% Yellow+25% Red),B (35% Blue+35% Green+18% Yellow+12% Red),C (27% Blue+30% Green+22% Yellow+21% Red) and D (42% Blue+28% Green+18% Yellow+12% Red)) on growth,immune function,carcass performance and welfare of AA broilers,aiming to provide theoretical and practical guidance for poultry production.A total of 600 1-day-old AA broilers were used.Each lighting treatment included 5 replicate groups with 30 chicks(15 male,15 female) 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 C light source significantly decreased average daily gain than A,B and D groups at 4-6 weeks by 14.45%,13.76% and 12.91%,respectively (P<0.05).C light source had a tendency to decrease average daily gain of 1-6 weeks (P=0.07).C light source significantly decreased the average daily feed intake of 4-6 weeks and 1-6 weeks compared to D light source (P<0.05).A light source significantly decreased feed gain ratio compared to D group by 9.14% (P<0.05).Antibody titers versus Newcastle disease (NDV) and avian influenza (Re-6) in D light source was significantly lower than that in other light groups (P<0.05).A significantly decrease of the gait score was observed in birds reared under A,C and D light source groups (by 44.97%,26.32% and 33.33%,respectively) compared to B light source (P<0.05).Spectral combination had no significant effect on eyeball development or carcass traits (P>0.05).It was concluded that A light source not only good for growth performance of growing period,but also increase the immune function and welfare of AA broilers.
