本試驗選定 R4 與 R5 代畜試紅公豬(R)與配高畜黑母豬(K)與雜交黑母豬(B)， 評估其雜交後裔(KR 與 BR)之繁殖性能。試驗共收集 15 胎繁殖性能資料。結 果顯示，KR 與BR 雜交豬的平均出生窩仔數為 11.00 ±4.69 與 10.30 ±3.83 頭;出 生活頭 數為 9.75 ± 5.19 與 9.40 ± 2.99 頭 ;出生 育成 率 88.64% 與 91.26%;出生重 1.66 ±0.29 與 1.83 ±0.21 公斤;3 周齡體重 8.04 ±1.04 與 8.92 ±1.47 公斤;3 周齡育成率 92.30 與 94.68%。綜合得知，KR 雜交豬有較 高的出生窩仔數與出生活頭數，但出生體重與三周體重則略低於 BR 雜交豬。

In this study, the R4 and R5 generations of LRI Duroc boar (R) were mated with sows of KHAPS black pig (K) and hybrid black pig (B), and the reproductive traits of their crossbred offspring (5 KR and 10 BR sows) were recorded. These reproductive traits includes litter size at birth, piglet born alive, survival rate at birth, body weight (BW) at birth, BW at 21 days of age, and survival rate at 21 days of age. The results showed that litter size at birth, piglet born alive, and survival rate at birth were, respectively, 11.00 ± 4.69, 9.75 ± 5.19 and 88.64% in KR sows; 10.30 ±3.83, 9.40 ±2.99, and 91.26% in BR sows. The body weight (BW) at birth, BW at 21 days of age, and survival rate at 21 days of age were, respectively, 1.66 ± 0.29, 8.04 ± 1.04, and 92.03% in KR sows; and 1.83 ± 0.21 kg, 8.92 +1.47 kg, and 94.68% in BR sows. From above results, it demonstrated that the litter size at birth, piglet born alive of KR sows were more than those of BR sows, but body weight (BW) at birth, BW at 21 days of age of KR sows were lower than the BR sows.
