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.
