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7d,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.
Abstract
The experiment aimed to investigate the effects of Buddleja officinalis powder 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％Buddleja officinalis powder 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 officinalis powder to the feed can improve yolk color,enhance production performance,improve egg quality,and improve serum biochemical indices,and adding 10％of Buddleja officinalis powder can be more effective.
