摘要
试验旨在研究饲粮添加百合干花粉对北京油鸡生产性能、蛋品质以及鸡蛋营养成分的影响.试验选取180只体重相近且健康状况良好的35周龄北京油鸡母鸡,随机分成3组,每组3个重复,每个重复20只鸡.对照组饲喂基础日粮,试验组在基础日粮的基础上分别添加2%和4%百合干花粉.预试期1周,正试期6周.结果显示:①与对照组相比,4%百合干花粉组平均日采食量和料蛋比显著降低(P<0.05);②与对照组相比,饲粮添加百合干花粉显著提高蛋壳颜色、蛋白高度、蛋黄色泽和哈氏单位(P<0.05),其中4%百合干花粉组的提高幅度最大.③与对照组相比,饲粮添加百合干花粉显著提高蛋黄蛋白质和叶黄素含量(P<0.05),其中4%百合干花粉组的提高幅度最大;2%和4%百合干花粉组蛋黄胆固醇含量显著降低(P<0.05).综上所述,饲粮添加4%百合干花粉显著提高北京油鸡蛋壳颜色、蛋白高度、蛋黄色泽、哈氏单位、蛋黄蛋白质和叶黄素含量,显著降低平均日采食量、料蛋比和蛋黄胆固醇含量.
Abstract
This study was aimed to investigate the effects of dried lily petal meal(DLPE)on production performance,egg quality and nutrients of Beijing-You chicken.A total of 180 healthy 35-week-age female Beijing-You chickens with similar weight and performance were selected and randomly divided into 3 groups with 3 replicates per group and 20 chickens in each replicate.Chickens fed with basal diet were labeled as the control group,and the experiment groups were fed basal diet with 2%and 4%DLPE supplementation respectively.The pre-experiment period was 1 week,and the formal experiment lasted for 6 weeks.The results showed as follows:①Compared with the control group,the average daily feed intake and feed to egg ratio in 4%DLPE group was significantly decreased(P<0.05).②Dietary DLPE could significantly increase eggshell color,albumen height,yolk color and Haugh unit of Beijing-You chicken(P<0.05),and the increase in 4%DLPE group was the largest.③ Dietary DLPE significantly increased yolk protein and lutein content(P<0.05),and the increase in 4%DLPE group was the largest;yolk cholesterol content in 2%and 4%DLPE group was significantly decreased(P<0.05).Therefore,dietary 4%DLPE significantly increased eggshell color,albumen height,yolk color,Haugh unit,yolk protein and lutein content,significantly decreased average daily feed intake,feed to egg ratio and yolk cholesterol content.
