2、发提供科学依据。【方法】以怀乡鸡A(小体型)、B(大体型)和C(颈部有圈浅黄色羽毛)3个品系的18周龄种鸡为研究对象,评估从开产到62周龄的产蛋性能,并分析其产蛋性状间的相关性。【结果】怀乡鸡C品系开产日龄显著晚于怀乡鸡A、B品系(P<0.05,下同);A、B和C品系的43周龄累计产蛋量分别为84.8、91.1和90.4枚,62周龄累计产蛋量分别为146.2、152.1和153.5枚。怀乡鸡A、B和C3个品系前期产蛋趋势基本一致,均在开产后第12或13周达产蛋高峰;A品系最高产蛋率出现在34周龄,达70.50%;B品系出现在33周龄,达77.00%;C品系出现在34周
3、龄,达79.14%。产蛋性状间的相关性分析结果表明,开产日龄与43周龄累计产蛋量呈显著负相关,与开产第2、3个月产蛋量呈极显著负相关(P4、1(2014)11-2071—05Egg-layingperformanceevaluationofnewHuaixiangchickenlinesandtheircorrelationanalysisofrelatedtraitsYEWei-qing1,DUBing-wang卜,CHENJian2,CHENYun-don92,LIUYi-lin2,LIDong—hual(1DepartmentofAnimalScience,GuangdongOceanUniversity,Zhanjiang,Guangdong524088,China;2GuangdongYingf5、uA画cultureLimitedCompany,Xinyi,Guangdong525300,China)Abstract:【Objective]Theegg-layingperformanceofnewHuaixiangchickenlinesandthecorrelationofitslayingtraitswereevaluatedandanalyzedinordertoprovidescientificbasisforimprovingvarietyresourcesconservationandutilizationandindustrydevelopmen6、tofHuaixiangchicken.【Method】ThreeHuaixiangchickenlinesasA,BandCat18-weekageweretakenasexperimentalmaterialstoevaluatetheiregg—layingperformancesfromatfirsteggto62-weekageandanalyzethecorrelationofegg-layingtraits.【Result]TheageatfirstgeeofHuaixiangchickenlineCwassignificantlaterthanthat7、oflineAandB(P<0.05,thesamebelow).TotaleggnumberoflineA,BandCat43-weekagewere84.8,91.1and90.4,re—spectively,and146.2,152.1and153.5at62一weekage,respectively.Theegg-layingproductionofthreelinesintheearlystagedisplayedbasicallyconsistentuend.andtotaleggnumberreachedpeakinthe12‘or13
