摘要

本试验旨在研究饲粮添加大豆黄酮对产蛋后期蛋鸡产蛋性能、蛋品质和血浆激素指标的影响。选择产蛋率相近的60周龄海兰褐蛋鸡180只,随机分为对照组和大豆黄酮组,每组6个重复,每个重复15只鸡。对照组饲喂基础饲粮,大豆黄酮组在基础饲粮中添加30 g/t的大豆黄酮。试验期8周。结果表明:与对照组相比,饲粮中添加30 g/t的大豆黄酮显著降低了试验第1~4周、第5~8周和第1~8周蛋鸡的料蛋比(P<0.05),显著提高了试验第5~8周和第1~8周蛋鸡的产蛋率(P<0.05),显著提高了试验第4和8周鸡蛋的哈氏单位(P<0.05),显著提高了试验第8周的血浆三碘甲状腺原氨酸、卵泡刺激素、黄体生成素、孕酮和雌二醇浓度(P<0.05)。综上所述,饲粮中添加30 g/t的大豆黄酮能够提高产蛋后期蛋鸡的产蛋性能、蛋品质和血浆激素浓度。

Abstract

This experiment was to study the effects of dietary daidzein on laying performance, egg quality and plasma hormone indices of laying hens during late laying cycle. One hundred and eighty 60-week-old Hyland brown hens with similar egg laying rate were selected and randomly divided into a control group and a daidzein group, with six replicates in each group and 15 chickens in each replicate. The control group was fed a basic diet, while the daidzein group was fed the basal diet supplemented with 30 g/t daidzein. The experiment lasted for 8 weeks. The results showed that compared with the control group, diets supplemented with 30 g/t daidzein significantly reduced the feed/egg of laying hens during weeks 1 to 4, weeks 5 to 8 and weeks 1 to 8 (P<0.05), significantly increased the egg laying rate of laying hens during weeks 5 to 8 and weeks 1 to 8 (P<0.05), besides, it significantly increased the Haugh units of egg at weeks 4 and 8 (P<0.05), and it also significantly increased the concentrations of triiodothyronine, follicle stimulating hormone, luteinizing hormone, progesterone, and estradiol in plasma of laying hens at week 8 (P<0.05). In summary, diets supplemented with 30 g/t daidzein can improve the laying performance, egg quality and plasma hormone concentrations.
