本研究旨在調查杜洛克母豬與配第6 代（K6）、第7 代（K7）高畜黑公豬（梅山 豬 × 杜洛克），其雜交後裔杜洛克級進一代之性能表現。母豬分娩後調查出生窩 仔數、出生活仔數、出生體重、21 日齡重、70 日齡重、左乳頭數、右乳頭數，以 及總乳頭數。本試驗一共收集83 胎母豬繁殖資料，合計758 頭雜交後裔性能資料。 試驗結果顯示，杜洛克母豬與配高畜黑公豬之出生窩仔數為8.73±2.2 頭、出生活 仔數為7.28±2.39 頭、出生體重為1.87±0.41 公斤、21 日齡體重為6.68±1.38 公斤、 70 日齡體重為28.62±4.54 公斤、左乳頭數為6.60±0.63 個、右乳頭數為6.64±0.67 個，總乳頭數為13.22±1.24 個。綜合上述，杜洛克母豬與配高畜黑公豬，雖沒明 顯增加窩仔數，卻能改善後裔仔豬生長性狀。

The purpose of this study was to investigate the performance of the F1 hybrid of Duroc sows sired with KHAPS black boars. The data of total number of piglets born (TNB), total number of piglets born alive (NBA), body weight at birth (BWB), body weight at 21 days (BW21), body weight at 70 days (BW70), teat number on the left side (TNL), teat number on the right side (TNR), total teat number (TTN) were recorded after piglets were born. Sow reproductive data (n = 83 parities) and records of progeny performance (n = 758) were collected. The results showed that the TNB, NBA, BWB, BW21, BW70, TNL, TNR and TTN were 8.73 ± 2.22, 7.28 ± 2.39, 1.87 ± 0.41 kg, 6.68 ± 1.38 kg, 28.62 ± 4.54 kg, 6.60 ± 0.63, 6.64 ± 0.67 and 13.22 ± 1.24, respectively. In summary, though the litter size of Duroc sows sired with KHAPS black boars did not increase remarkably, the growth performance of F1 progeny piglets was improved.
