摘　　要：试验旨在研究密蒙花干粉对鹌鹑蛋黄颜色、蛋中脂肪含量、生产性能、蛋品质及血清生化指标的影响。选择90日龄健康鹌鹑600只,按体重相近原则随机分为3组,每组5个重复,每个重复40只鹌鹑。对照组饲喂基础饲粮,CK1组和CK2组在基础饲粮中添加5%、10%密蒙花干粉。预试期7 d,正式试验期30 d。结果显示:与对照组相比,CK2组蛋黄颜色极显著加深(P<0.01),CK1组和CK2组平均蛋重显著升高(P<0.05),平均日采食量、料蛋比显著降低(P<0.05)。与对照组相比,试验组蛋黄占比均显著升高(P<0.05),甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白(HDL)含量显著降低(P<0.05),谷草转氨酶(AST)、谷丙转氨酶(ALT)、碱性磷酸酶(ALP)活性及血糖(GLU)含量显著降低(P<0.05)。研究表明,饲粮中添加5%和10%密蒙花干粉能够改善蛋黄颜色,提高生产性能和蛋品质,改善血清生化指标,且添加10%的密蒙花干粉效果较好。The experiment aimed to investigate the effects of Buddlejaofficinalispowder on the yolk color,fat content in eggs,production performance,egg quality,and serum biochemical indices in quails.A total of 600 healthy 90-day-old quails were selected and randomly divided into three groups based on similar body weight,with five replicates per group and 40 quails per replicate.The control group was fed a basic diet,while the CK1 and CK2 groups were supplemented with 5%and 10%Buddlejaofficinalispowder of the basic diet,respectively.The preliminary period lasted for seven days,followed by a formal experimental period of 30 days.The results showed that compared to the control group,the yolk color of the CK2 groups deepened extremely(P<0.01),the average egg weight in the CK1 and CK2 increased significantly(P<0.05),and the daily feed intake and feed-to-egg ratio decreased significantly(P<0.05).Compared to the control group,the yolk proportion in the experimental groups increased significantly(P<0.05),and the contentrations of triglycerides(TG),total cholesterol(TC),and high-density lipoprotein(HDL)decreased significantly(P<0.05),the activities of aspartate aminotransferase(AST),alanine aminotransferase(ALT),and alkaline phosphatase(ALP),as well as the content of glucose(GLU)decreased significantly(P<0.05).The study indicates that the addition of 5%and 10%Buddleja officinalispowder to the feed can improve yolk color,enhance production performance,improve egg quality,and improve serum biochemical indices,and adding 10%of Buddlejaofficinalispowder can be more effective.
