Abstract

This experiment was conducted to measure the effects of olive leaf powder on performance, egg yield, egg quality and yolk cholesterol level of laying hens. A total of 120 Lohmann Brown laying hens of 22 weeks old were used in this experiment. The birds were fed on standard layer diets containing 0, 1%, 2%, or 3% olive leaf powder for 8 weeks. Egg weight and yield were recorded daily; feed intake weekly; egg quality and cholesterol content at the end of the trial. Olive leaf powder had no effect on feed intake, egg weight, egg yield and feed conversion ratio (p>0.05) while olive leaf powder increased final body weight of hens (p<0.05). Dietary olive leaf powder increased yellowness in yolk color (p<0.01) without affecting other quality parameters. Yolk cholesterol content was tended to decrease about 10% (p>0.05). To conclude, olive leaf powder can be used for reducing egg yolk cholesterol content and egg yolk coloring agent in layer diets.

摘要

本实验旨在测定橄榄叶粉对蛋鸡生产性能、产蛋量、蛋品质及蛋黄胆固醇水平的影响。本实验共使用120只22周龄的罗曼褐蛋鸡。这些鸡被饲喂含0%、1%、2%或3%橄榄叶粉的标准蛋鸡日粮,为期8周。每天记录蛋重和产蛋量;每周记录采食量;试验结束时记录蛋品质和胆固醇含量。橄榄叶粉对采食量、蛋重、产蛋量和饲料转化率无影响(p>0.05),而橄榄叶粉增加了母鸡的终体重(p<0.05)。日粮中的橄榄叶粉增加了蛋黄颜色的黄度(p<0.01),而不影响其他品质参数。蛋黄胆固醇含量有降低约10%的趋势(p>0.05)。综上所述,橄榄叶粉可用于降低蛋鸡日粮中的蛋黄胆固醇含量和作为蛋黄着色剂。
