摘　　要：通过分析怀乡鸡第四世代A、B品系的产蛋性能,为怀乡鸡种质资源的评价、保护和利用提供依据。结果表明:怀乡鸡第四世代A、B两品系均在22周开产,A品系产蛋率在31周龄达到最高值82.33%,B品系产蛋率在30周龄达到最高值83.53%。A、B两品系产蛋率总体良好,但A品系在21~52周龄的平均产蛋率高于B品系2.95%。43周龄A、B两品系只均累计产蛋数分别为92.41枚和91.47枚;52周龄A、B系只均累计产蛋数分别为129.78枚,122.88枚,A品系略多于B品系。A、B两品系的蛋重均随周龄的增加而增加,且在35周龄达到最大值,分别为49.20 g和48.78 g,A品系总体平均蛋重要略低于B品系。综合各项指标的比较,怀乡鸡第四世代A、B两品系作为地方优质鸡种产蛋性能良好,A品系的产蛋率、只均累计产蛋数均比B品系高。The purpose of this paper is to provide the basis for the evaluation,protection and utilization of Huaixiang chicken germplasm resources by analyzing the egg production performance of Huaixiang chicken strains A and B of the fourth generation.The results showed that the laying rate of strain A and strain B reached the highest value of 82.33%at the age of 31 weeks and 83.53%at the age of 30 weeks.A.The laying rate of strain B was generally good,but the average laying rate of strain a was 2.95%higher than that of strain B at 21-52 weeks old.The cumulative egg production of 43 week old strain A and B were 92.41 and 91.47,respectively;The cumulative egg production of strain A and strain B at 52 weeks of age were 129.78 and 122.88,respectively.A.The average egg weight of strain a was slightly lower than that of strain B.The results showed that the laying performance of Huaixiang chicken strain A and B was better than that of strain B.the laying rate of strain a was higher than that of strain B.
