受精率對養豬產業競增能力影響甚鉅，精液性能檢定技術的發展有助提升母豬受精成功機率。本試驗目的旨在觀察台灣杜洛克級進公豬之精液性能表現。試驗利用精子計數器與流式細胞儀觀察R1代（杜洛克母豬 × 高畜黑公豬；N = 4）與R2代公豬（杜洛克母豬 × R1代公豬；N = 4）之精子體能，包括精液量、精子濃度、總精子數、粒線體膜去極化及精子活力，每頭平均檢測次數2 ~ 4次。試驗觀察R1與R2代公豬在平均檢測日齡分別為604.38 ± 53.12與578.93 ± 57.81（天）精液性能的表現。結果顯示，精液量分別為185.63 ± 71.19與244.36 ± 127.69（毫升）；精子濃度分別為3.17 ± 0.90與2.92 ± 1.00 （億/毫升）；總精子數分別為588.66±49.70與713.70±128.22（億）；粒線體膜去極化分別為13.77 ± 5.65與15.94± 10.33（%）；精子活力分別為75.92 ± 18.23與81.84 ± 9.64（%）。綜合結果得知，R2代公豬精液性能表現較R1代公豬為佳，顯示台灣杜洛克公豬經級進育種後，精液性能已明顯提升，後續仍有待評估。

Fertility can seriously affect the competitiveness of pig industry. Development of semen quality evaluation is helpful for sow’s fertility. The purpose of this study was to evaluate the semen quality of Taiwan Duroc boars followed by upgrading breeding. We used the sperm counter and flow cytometry to observe semen quality, including semen volume, sperm concentration, total sperm count, mitopotentia and sperm motility, of R1 (Duroc sow × KHAPS black boar, N = 4) and R2 boar (Duroc sow × R1 boar, N = 4). Semen quality evaluation was performed for 2 to 4 times per boar. The average evaluated-day-old of R1 and R2 boars were 604.38 ± 53.12 and 578.93 ± 57.81 day, respectively. The semen volume, sperm concentration, total sperm count, mitopotentia and sperm motility were 185.63 ± 71.19 (mL), 3.17 ± 0.90 (108 / mL) , 588.66 ± 49.70 (109), 13.77 ± 5.65 (%) and 75.92 ± 18.23 (%) in R1 boars; and 244.36 ± 127.69 (mL), 2.92 ± 1.00 (108 / mL), 713.70 ± 128.22 (109), 15.94 ± 10.33 (%) and 81.84 ± 9.64 (%) in R2 boars, respectively. The results showed that semen performance of the Taiwan Duroc boar were obviously increased after upgrading bleeding and were needed to evaluate in the future programs.
