摘  要:
为了研究二郎山山地鸡的产蛋规律,试验以二郎山山地鸡SD02与SD03品系一世代300日龄产蛋量建立产蛋曲线,并采用伍德模型、分室模型与杨宁模型对两品系进行产蛋率曲线拟合,然后对实际产蛋率曲线进行分析。结果表明:品系SD03的产蛋性能优于SD02。经过拟合分析,SD02品系的伍德模型、分室模型、杨宁模型的拟合度(R2值)分别是0.811 7,0.906 2,0.967 7,SD03品系拟合度分别是0.796 9,0.910 2,0.954 8;杨宁模型拟合效果最佳。

摘  要:
To study the laying laws of Erlang mountaineous chicken,the egg curves of the first generation of Lines SD02 and SD03 in Erlang mountainous chicken were established via adopting their 300-day old egg production.Meanwhile,the Wood model,McMillian model and Yang Ning model were used to create the fitting curves.The actual egg production curves were analyzed.The results showed that the egg production performance of SD03 was better than that of SD02.The Fitting analysis showed that the R2 values for line SD02 in three models were 0.811 7,0.906 2,0.967 7 respectedly,and the R2 values for line SD03 were 0.796 9,0.910 2,0.954 8 respectedly.It is conclded that the fitting effect of Yang Ning model is the best one compared with the other models.
