為了解豐輝牧場紅羽土雞選育族群之產蛋性能，分析該族群 G8 世代候選種母雞之產第 1 個蛋的日齡、達 280 日齡之產蛋紀錄，A 品系、B 品系及 C 品系分別有 68 隻、50 隻及 168 隻母雞，共 266 隻。母雞產第 1 枚蛋的日齡從 150 日齡到 210 日齡，母雞產第 1 枚蛋的 平均日齡為 185±13 天；母雞達 280 日齡產蛋數最少為 22 枚，最多可達 125 枚，母雞達 280 日齡平均產蛋數與平均產蛋率為 70.2±18.0 枚與 73.6±15.4%。不同品系母雞產第 1 枚 蛋的日齡與達 280 日齡產蛋數在品系間存在極顯著差異（P < 0.001)。在 A 品系、B 品系 及 C 品系母雞產第 1 枚蛋的日齡分別為 190±11 天、174±14 天及 186±10 天，達 280 日 齡產蛋數分別為 58.4±16.5 枚、76.2±21.9 枚及 73.5±14.5 枚。結果顯示，豐輝牧場紅羽土雞 選育族群母雞有良好的產蛋性能。

To understand the egg production performance of red feather chickens in Feng Hui breeding farm. Totally, 266 hens from 3 lines of current selection breeding flock including 68 hens of A line, 168 hens of C line and 50 hens of E line were carried out the age at first egg (AFE) and egg number up to 280 days of age (EN280) test. The AFE of hens was ranged from 150 to 210 days, and the average AFE of hens was 185±13 days. The EN280 of hens was ranged from 22 to 125 eggs, and the average EN280 and egg production rate of hens were 70.2±18.0 eggs and 73.6±15.4%, respectively. There were significant differences in the age at first egg(AFE) and egg number up to 40 weeks of age (EN40) were detected among the three lines (P <0.001). The average of AFE of hens in A line, C line and E line were 190±11 days, 186±10 days and 174±14 days, respectively. And the mean of EN280 of hens in A line, C line and E line were 58.4±16.5 eggs, 73.5±14.5 eggs and 76.2±21.9 eggs, respectively. Our result shows the hens of red feather native chicken selection flock in Feng Hui breeding farm could be provided with good egg production performance.
