摘要

本试验旨在研究饲粮中添加大豆黄酮对产蛋后期地方蛋鸡生产性能、蛋品质和血浆激素指标的影响。试验选用体重及产蛋率相近的55周龄如皋黄鸡蛋鸡192只,随机分为2组,每组6个重复,每个重复16只鸡。对照组饲喂基础饲粮,试验组饲喂在基础饲粮中添加60 mg/kg大豆黄酮的试验饲粮。预试期2周,正试期14周。结果表明:1)试验组产蛋率显著高于对照组(P<0.05),试验组死亡率、平均蛋重、平均日采食量和料蛋比与对照组相比较差异不显著(P>0.05)。2)试验组鸡蛋哈氏单位显著高于对照组(P<0.05),试验组其他蛋品质指标与对照组相比较差异不显著(P>0.05)。3)试验组血浆雌二醇(E2)含量显著高于对照组(P<0.05),试验组血浆卵泡刺激素(FSH)含量显著低于对照组(P<0.05),试验组其他血浆激素指标与对照组相比较差异不显著(P>0.05)。综上所述,饲粮添加60 mg/kg大豆黄酮能改善产蛋后期地方蛋鸡生产性能、蛋品质以及血浆激素指标。

Abstract

This experiment was conducted to investigate the effects of dietary daidzein on performance, egg quality and plasma hormone indices of local laying hens during late laying cycle. A total of 192 fifty-five-week-old Rugao yellow laying hens with similar body weight and laying rate were randomly assigned to 2 groups with 6 replicates in each group and 16 hens in each replicate. Hens in the control group were fed a basal diet, the others in the experimental group were fed the basal diet supplemented with 60 mg/kg daidzein. The pre-test period lasted for 2 weeks and the trial period lasted for 14 weeks. The results showed as follows:1) the laying rate of experimental group was significantly higher than that of control group (P<0.05), however, the mortality, average egg weight, average daily feed intake and ratio of feed to egg had no significant differences compared with the control group (P>0.05). 2) The egg Haugh unit of experimental group was significantly higher than that of control group (P<0.05), however, the other egg quality indices had no significant differences compared with the control group (P>0.05). 3) The plasma estradiol content of experimental group was significantly higher than that of control group (P<0.05), the plasma follicle stimulating hormone content of experimental group was significantly lower than that of control group (P<0.05), however, the other plasma hormone indices had no significant differences compared with the control group (P>0.05). In conclusion, dietary supplemented with 60 mg/kg daidzein can improve performance, egg quality and plasma hormone indices of local laying hens during late laying cycle.
