日粮酵母硒添加水平对北京油鸡生产性能、蛋品质、蛋硒含量和抗氧化能力的影响
Effects of dietary yeast selenium supplemental levels on production performance,egg quality,egg selenium content,and antioxidant capacity of Beijing You laying hens
摘要
Abstract
The experiment aimed to investigate the effects of different levels of dietary yeast selenium on the productive performance,egg quality,selenium deposition in eggs,and antioxidant capacity in the serum of Beijing You laying hens.A total of 504 healthy Beijing You laying hens from the same batch were randomly divided into seven groups,with six replicates per group and 12 chickens per replicate.Group A was fed a basal diet without additional selenium sources,while Group B to Group G were fed the basal diet supplemented with 0.1,0.2,0.3,0.4,0.5,0.6 mg/kg of yeast selenium(calculated as selenium),respectively.The experimental period was 63 days,including a seven days pre-experimental period and a 56 days formal experimental period.The results showed that the level of yeast selenium addition had no significant effect on the productive performance of Beijing You laying hens(P＞0.05).Group E to Group G had significantly higher yolk color than Group A(P＜0.05),but the level of yeast selenium addition had no significant effect on the Haugh units,albumen height,egg shape index,eggshell color,eggshell strength,and eggshell thickness(P＞0.05).The addition of dietary yeast selenium could increase the selenium content in the yolk,egg white,and whole egg,as the level of yeast selenium addition increased,the total antioxidant capacity(T-AOC)in the serum of the hens significantly increased(P＜0.05),the content of malondialdehyde(MDA)showed a decreasing trend(P＞0.05),and the activity of glutathione peroxidase(GSH-Px)in the serum of Group B to Group G was significantly higher than that of Group A(P＜0.05).The study indicates that the addition of different levels of yeast selenium has no significant effect on the productive performance of Beijing You laying hens,has a tendency to improve yolk color,can increase the selenium content in eggs and serum antioxidant capacity,and it is recommended that the dietary addition level of yeast selenium should reach 0.3 mg/kg.关键词
