天然着色添加剂提高鹌鹑蛋黄品质的研究

将120只健康产蛋鹌鹑分为2组，每组60只．对照组饲喂基础日粮，试验组饲喂含天然着色添加剂0．7％的基础日粮．试验期15d，探讨天然着色添加剂对鹌鹑蛋黄品质的影响效果．结果表明，试验组蛋黄色泽度比对照组平均提高约5个级别（P〈0．01）；蛋黄指数也明显提高（P〈0．01）．鹌鹑蛋盐化后，同组蛋黄色泽度比盐化前鲜蛋明显提高（P〈0．05），蛋黄指数显著提高（P〈0．01）；试验组蛋黄色泽度和蛋黄指数极显著高于对照组（P〈0．01）．试验组产蛋率比对照组高3．78％（P〉0．05），料蛋比下降3．9％．说明该天然着色添加剂对提高鹌鹁蛋黄品质有明显作用，具有推广应用价值．

Effect of Natural Complex Additive on Yolk Qualities of Quails

120 quails were randomly allotted into 2 groups,the controlled group was fed basal diet,while the treated group was fed basal diet added 0.7% natural complex additive.15 days of experiment led to,the results that RCF of treated group was improved about 5 levels than that of the controlled group(P<0.01) and yolk index was also improved significantly(P<0.01).RCF(P<0.05) and yolk index(P<0.01) of salted eggs improved that of the fresh eggs.And in treated groupt,he two indexes were also significant higher than those in controlled group(P<0.01).Furthermorel,aying rate in treated group was improved by 3.78% and feed-egg ratio decreased 3.9% compared to the control group,which indicated that natural complex additive can significantly improve the yolk qualities of quails and is worthy of applying in practice.
