為了解豐輝牧場紅羽土雞選育族群之種蛋受精率與孵化率，以該族群 G8 世代 3 個品系 152 隻 7 月齡種雞進行配種試驗。選用 54 隻 A 品系母雞、57 隻 C 品系母雞及 41 隻 E 品系母雞與其同一品系 1 隻公雞以人工授精進行純品系配種，每 5 天進行人工授精一次， 種蛋於配種後第 3 天開始收集，種蛋每天收集一次，置於 16-17 ℃ 貯蛋室。每收集 10 天 的 種蛋回溫後進行入孵一批，連續3 批。入孵後第 8 天進行驗蛋，第 18 天移入發生機，第 21 天出雛。孵化機與發生機溫度分別為 100℉ 與 99℉。A、C 及 E 品系之平均種蛋受精率與 受精蛋孵化率分別為 92.8% （956/1,036)與 86.6%（828/956)、91.0%（1,238/1,360)與 79.1% （979/ 1,238)及 90.2%（753/835)與 76.4%（575/753)。選育族群 3 個批次所有種蛋之平均 種蛋受精率與受精蛋孵化率分別為 91.2% （2,947/3,231)與 80.8%（2,382/2,947)。比較種蛋 受精率與受精蛋孵化率在批次間皆無顯著差異（P > 0.05)，種蛋受精率在品系間亦無顯著差 異（P = 0.088)，然而受精蛋孵化率則在品系間存在顯著差異（P < 0.05)，A 品系母雞之受精 蛋孵化率顯著較E 品系者佳。結果顯示，該場紅羽土雞選育族群平均種蛋受精率可達 90% 以 上，受精蛋孵化率可達 80% 以上。
關鍵語：受精率、孵化率、紅羽土雞

To understand the fertility and hatchability of red feathered chickens selection flock in Feng Hui breeding farm. One hundred and fifty two hens including 54 hens of A line, 57 hens of C line and 41 hens of E line were used for fertility and hatchability test. All hens of each line were mated with 1 roaster of each line by pure line artificial insemination every 5-day. The hatching eggs were collected daily and stored at 16 ℃ for 10 days per batch before setting in incubator. Three continued batches of hatching eggs were carried out for this trial. The average fertility and hatchability of fertilized eggs were 92.8% (956/1,036) and 86.6% (828/956) in A line, 91.0% (1,238/1,360) and 79.1% (979/ 1,238) in C line, and 90.2% (753/835) and 76.4% (575/753) in E line, respectively. The average fertility and hatchability of fertilized eggs of all hatching eggs in this trial were 91.2% (2,947/3,231) and 80.8% (2,382/2,947). There were none significant differences in fertility and hatchability of fertilized eggs detected among the three batches and fertility detected among the three lines(P > 0.05). However, There was significant difference in the hatchability of fertilized eggs detected among the three lines (P > 0.05). The hatchability of fertilized eggs of A line was better than that of E line. Result shows the average fertility of the selection flock reached more than 90%, and the hatchability of fertilized eggs of the selection flock could reach more than 80% in Feng Hui breeding farm.
