| 摘 要： | 【目的】筛选适合四层层叠本交笼鸡舍种鸡的最佳产蛋曲线数学模型。【方法】所有试验鸡均饲喂于全封闭式鸡舍四层层叠式本交笼,采集19~61周龄的海兰褐父母代种鸡的产蛋记录,运用伍德模型、McMillan模型和杨宁模型拟合种鸡产蛋率,并比对分析3种模型的拟合效果。【结果】3种模型均可用于产蛋率拟合,杨宁模型、McMillan模型和伍德模型R值分别为0.997 87、0.964 63和0.764 57,说明杨宁模型的拟合效果最好,McMillan模型次之,伍德模型最差。杨宁模型更适合实际观测数据,适合程度约为McMillan模型的1.160 37×1026倍,为伍德模型的1.599 31×1042倍。不同生产阶段的产蛋率呈不同特征,与海兰褐标准产蛋率相比,种鸡在产蛋率上升阶段的实际观测值低于相同周龄的标准值。【结论】杨宁模型最适合四层层叠本交笼鸡舍种鸡产蛋率拟合,生产过程中要根据模型和产蛋曲线特征科学合理地饲养管理,以达到生产效益最优化。
