摘要: 为了解笼养淮南麻黄鸡的产蛋规律, 选取Wood模型、McMillan模型、Yang模型和Ali-Schaeffer模型对淮南麻黄鸡2260周龄的产蛋曲线进行拟合分析。结果表明, 4种数学模型拟合效果存在差异, 拟合度 (R2) 范围为0.3910.975, Wood模型 (R2=0.391) 不适合用于笼养淮南麻黄鸡产蛋曲线的拟合。McMillan模型、Yang模型和Ali-Schaeffer模型均能较好地拟合笼养淮南麻黄鸡产蛋曲线, 其中Yang模型拟合效果最好 (R2=0.975) 。因此, 4种模型中, Yang模型用于笼养淮南麻黄鸡产蛋曲线拟合最为合适。Abstract: In order to understand the egg production rule of Huainan partridge chicken, the egg production curve of Huainan partridge chicken from 22to 60weeks old was analyzed and fitted with four mathematical models of Wood, McMillan, Yang and Ali-Schaeffer.The results showed that, the goodness of fit (R2) of four models were different and ranged from 0.391to 0.975.Wood model was not appropriate to predict the variation for egg production curve of caged Huainan partridge chicken (R2=0.391) .The egg production curves could be fitted well with three models of McMillan, Yang and Ali-Schaeffer, the fitness of Yang model was the highest of all (R2=0.975) .The result indicated that Yang model was the optimum model of egg production for caged Huainan partridge chicken.
