为了掌握海兰褐蛋鸡产蛋前期生产性能的特点及规律，对19~24周龄的有关性状进行了测定，计算了产蛋量和产蛋率等指标，进一步分析了性状间的相关性并建立了相应的回归方程。研究结果表明：产蛋前期的性能表现良好，与品种标准基本吻合；周龄、只日耗料量与产蛋各性状间有强的正相关（p＜0.01）；以周龄（X1）和只日耗料量（X3）为自变量，以X4、X5、X6、X7、X8为依变量分别建立回归方程，均极显著（p＜0.01）。此回归方程可用于产蛋性能的推测及生产管理与控制。
為瞭掌握海蘭褐蛋鷄產蛋前期生產性能的特點及規律，對19~24週齡的有關性狀進行瞭測定，計算瞭產蛋量和產蛋率等指標，進一步分析瞭性狀間的相關性併建立瞭相應的迴歸方程。研究結果錶明：產蛋前期的性能錶現良好，與品種標準基本吻閤；週齡、隻日耗料量與產蛋各性狀間有彊的正相關（p＜0.01）；以週齡（X1）和隻日耗料量（X3）為自變量，以X4、X5、X6、X7、X8為依變量分彆建立迴歸方程，均極顯著（p＜0.01）。此迴歸方程可用于產蛋性能的推測及生產管理與控製。

The characteristics and rules of early production performance of Hyline Brown Layers was studied in this paper. The traits such as egg production and laying rate were calculated, the correlation among the traits was analyzed and the corresponding regression equation was established in Hyline Brown Layers form 19 to 24 weeks old. The results showed that the early laying period performance of Hyline Brown Layers was good and was consis-tent with the breed standard. The weeks old, feed consumption of each layer per day had strong positive correlation with the traits of laying (P<0.01). The regression equations were established employing weeks old (X1) and feed consumption of each layer per day (X3) as independent variables, with X4, X5, X6, X7, X8 as the dependent variables, respectively. The equations were very significant (P<0.01). The equations can be used for speculation of laying performance and production management and control.
