公豬精液品質定期的鏡檢評估，可提前預測公豬精液的品質，以提高母豬受孕的機率。傳統 精液品質評估的項目有精液濃度、精子活力、可生育精蟲百分比，以及異常精子型態等，但 這些評估項目對於預測公豬生育力仍顯貧乏不足，並無法精準預測精蟲的表現。本試驗選擇 3 頭平均2 歲齡R6 代畜試紅豬針對臺灣夏季 7~9 月精子體能性狀進行檢測，試驗分析項目 與結果分別為精液量 240.00 ± 66.55、182.50 ± 38.41 與 177.58 ± 61.71 毫升、平均精液濃度 3.93 ± 9.2、3.24 ± 8.89 與 3.43 ± 1.45 億/毫升、平均總精子數 897 ± 164、571 ± 133 與 608 ± 216 億、活精子 89.67± 4.30、85.52 ± 10.08、75.51 ± 22.00 %、活精子且頭帽完整性 76.85 ± 6.14、 69.86 ± 14.37 與 60.64 ± 20.82 %、活精子中粒線體破損率 17.33 ± 2.79、21.81 ± 19.68 與 19.29 ± 13.86 % 與活精子中染色體完整 93.48 ± 2.05、96.23 ± 1.58 與 87.28 ± 27.37 %。畜試 紅豬未飼養於水簾式豬舍，總體而言，精子體能表現優異，並未受夏季熱緊迫影響。

An early prediction of semen quality by regular microscopic examination would help predicting donor sperm fertility ability thereby elevating the pregnancy rate of sows. It is not enough to accurately predict fertility ability of boar via the traditional semen assessment includes sperm concentration, vitality and morphology, and etc. Three R6 LRI Duroc boars at age of 2 years old (on average) were used in this study for assessment of semen quality in summer season (July, August, and September). All boars were not raised in wet pad and forced ventilation house. The results showed that respectively, in July, August and September, the semen volume was 240.00 ± 66.55, 182.50 ± 38.41 and 177.58 ± 61.71 mL; average semen density was 3.93 ± 9.2, 3.24 ± 8.89, 3.43 ± 1.45×108/mL; average sperm count was 897 ± 164, 571 ± 133 and 608 ± 216 ×108; percentage of live sperm was 89.67 ± 4.30, 85.52 ± 10.08 and 75.51 ± 22.00 %; percentage of live sperm with acrosome intact was 76.85 ± 6.14, 69.86 ± 14.37 and 60.64 ± 20.82 %; percentage of mitochondrial status was 17.33 ± 2.79, 21.81 ± 19.68 and 19.29 ± 13.86 %; and percentage of live sperm with normal structural chromosome was 93.48 ± 2.05, 96.23 ± 1.58 and 87.28 ± 27.37 %. These finding demonstrated that sperm quality of LRI Duroc boar not only did not influenced by summer heat stress, but even at high quality.
