摘 要:文章旨在研究发酵饲料对海兰褐壳蛋鸡产蛋性能、蛋品质及血清生化指标的影响。试验选取健康且产蛋率相近的54周龄海兰褐壳蛋鸡480只,随机均分为4组,每组10个重复,每个重复12只。对照组饲喂基础日粮,试验组在基础日粮中分别添加2%、4%和6%发酵饲料。预饲期1周,试验期6周。结果显示,4%发酵饲料组和6%发酵饲料组蛋鸡料蛋比显著降低7.23%和5.96%(P<0.05)。6%发酵饲料组的蛋黄颜色显著提高(P<0.05)。4%发酵饲料组和6%发酵饲料组的哈氏单位显著高于对照组(P<0.05)。与对照组相比,添加发酵饲料组的血清胆固醇含量分别显著降低20.4%,25.87%和23.55%(P<0.05)。结论:在本试验条件下,饲喂发酵饲料能降低蛋鸡料蛋比,改善蛋黄颜色,提高哈氏单位,降低血清胆固醇,且以6%添加量最为适宜。The experiment aims to investigate the effects of adding different amounts of fermented feed to the feed of laying hens on their production performance,egg quality,and serum biochemical indicators.Select 480 Hailan brown shell laying hens at 54 weeks of age with similar body weight and egg laying performance,Randomly divided into 4 experimental groups,each with 10 replicates and 12 chickens per replicate.The control group received a conventional basal diet,while the experimental group received fermented feed supplemented with 2%,4%,and 6%lactobacilli and brewing yeast as fermentation strains in the basic diet.The pre trial period for the experiment is 1 week,and the trial period is 6 weeks.The results of the study showed that The feed to egg ratio of laying hens in the 4%fermented feed group and 6%fermented feed group significantly decreased by 7.23%and 5.96%(P<0.05).The egg yolk color of the 6%fermented feed group was significantly improved(P<0.05).Compared to the control group,the Hasselblad units of the 4%fermented feed group and the 6%fermented feed group were significantly increased.The serum cholesterol content of the group with added fermented feed was significantly lower than that of the control group by 20.4%,25.87%,and 23.55%,respectively(P<0.05).The experimental conclusion is that under the experimental conditions of this study,feeding Hailan brown shell laying hens fermented feed can reduce the feed to egg ratio,improve the color grade of egg yolks,and increase the Hasselblad unit,and lower serum cholesterol,with a 6%addition being the most suitable.
