LED组合光谱对白羽肉鸡生长、屠宰性能及抗应激的影响
Effects of different combinations of LED spectra on growth, carcass traits and anti-stress ability of AA broilers
摘要
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.关键词
