摘　　要：为筛选四层层叠本交笼种鸡最佳生长曲线模型,运用Logistic模型、Gompertz模型和Von Bertalanffy模型分别对海兰褐父母代种鸡育雏育成期(1～12周龄)和产蛋期(18～57周龄)体重进行曲线拟合和分析。结果显示:1～12周龄雏鸡(公雏和母雏)的体重均呈逐渐上升趋势,并且公雏的体重生长速度快于母鸡。产蛋期母鸡体重总体呈上升趋势,但51周龄后出现波动。Logistic模型是最适合于拟合公雏体重的模型,Gompertz模型是最适合于拟合母雏体重的模型,而三种模型均可用于产蛋期母鸡体重的拟合。产蛋期母鸡的实际观测值以及拟合值均高于该时期母鸡标准体重上限,建议应在满足母鸡营养需要的前提下适当减料。To screen the best growth curve model of layer breeders in natural mating cages with four overlap tiers,body weight of Hy-Line Brown parent stock layers during the growing(1 to 12 weeks of age) and laying period(18 to 57 weeks of age) were fitted and analyzed using Logistic model, Gompertz model and Von Bertalanffy model. The results displayed a gradual upward trend in body weight in chicks(including cocks and pullets) and that cocks grew faster than pullets during the 1 to 12 weeks of age. Hens weight followed a generally upward trend during the laying period, but exhibited fluctuation after the 51 weeks of age. Logistic model was the best optimized model for fitting of cock weight,and Gompertz model for pullet weight, but all three kinds of models were available for hens. Moreover, measurements and fitting values of hen weight were higher than the upper limit of standard weight of hens in the corresponding period,suggesting an appropriate reduction of feed under the premise of meeting the nutritional requirements of hens.
