摘　　要：本研究通过分析暗斑蛋个体与产正常蛋个体在输卵管、腹脂率、皮脂厚等方面存在的差异,可为深入研究鸡蛋暗斑形成机制提供参考。本试验以35周龄寿光母鸡为研究对象,从群体中筛选出明显产暗斑蛋个体和明显不产暗斑蛋个体各30只,分别为正常组和暗斑组,比较屠体重、腹脂率、肌间脂宽、输卵管长度和输卵管重量在两组之间存在的差异。研究结果表明:产暗斑蛋个体与产正常蛋个体在屠体重、皮脂厚、肌间脂宽指标之间几乎没有差异,产暗斑蛋个体的腹脂率高于产正常蛋个体,输卵管长度短于正常组,输卵管重低于正常组,但均差异不显著(P>0.05)。结果表明暗斑蛋的形成与肌间脂肪、体内脂肪沉积关系不密切,输卵管特性值得关注。In this study,the differences of oviduct and abdominal fat rate between translucent egg and normal egg were analyzed in order to provide reference for the further study of the mechanism of egg dark spot formation.In this experiment,35-week-old Shouguang hens were selected from the population to produce 30 translucent eggs and 30 normal eggs,which were normal group and translucent group,respectively.The carcass weight,abdominal fat rate,intermuscular fat width,fallopian tube length and fallopian tube weight were compared between the two groups.The results showed that there was almost no difference in carcass weight,sebum thickness and intermuscular fat width between translucent egg laying and normal egg laying.The abdominal fat rate of translucent egg laying individual was higher than that of normal egg laying individual,and the length of oviduct was shorter than that of normal egg laying group.The weight of oviduct in the normal group was lower than that in the normal group,but the difference was not significant(P>0.05).The results showed that the formation of translucent eggs was not closely related to intermuscular fat and body fat deposition,and the characteristics of oviduct were worthy of attention.
