密蒙花干粉对产蛋鹌鹑蛋黄颜色、 脂肪含量、生产性能、蛋品质及血清生化指标的影响

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.
