论文摘要
背景和客观：几项研究证实，母鸡的年龄对外部和内部鸡蛋质量特征产生了巨大影响。如果不认真考虑鸡蛋质量特征和母鸡的年龄，则鸡蛋产量可能会面临严重的风险。进行了这项研究是为了分析旧产母中某些内部和外卵质量特征之间的表型相关性。材料和方法：在3周内收集了总共288个85周龄的Hy-Line Brown Browing母鸡，并评估了其内部和外鸡蛋特征。结果：旧产鸡蛋中的卵质量特征之间的表型相关性表明对壳和蛋白质质量产生负面影响，但不影响蛋黄质量的特征。结论：这项研究有助于理解，将母鸡在80周以上饲养将对鸡蛋质量特征产生负面影响。
Background and Objective: Several studies confirm that the age of hens has a tremendous impact on external and internal egg quality characteristics. Egg production could be at serious risk if egg quality characteristics and age of hens are not seriously considered. This study was conducted to analyze the phenotypic correlations between some internal and external egg quality characteristics in old laying hens. Materials and Methods: A total of 288 eggs of 85-week-old Hy-Line Brown laying hens were collected during 3 weeks and their internal and external egg characteristics were evaluated. Results: Phenotypic correlations between egg quality characteristics in old laying hens indicate a negative impact on shell and albumen quality but not affected yolk quality characteristics. Conclusion: This study helps to understand that raising laying hens above 80 weeks would have a negative impact on egg quality characteristics.
