由於熱季時因高溫與高濕度對公豬造成熱緊迫影響，導致精液品質出現降低情形，及如 何確保公豬群每日生產精子之穩定性並解決全年供給品質穩定之公豬精液為豬隻育種 計畫的重要基石，本試驗目的乃藉由檢定公豬涼熱季之精液品質，評選涼熱季期間仍然 保有一定水平的精液質與量之公豬，作為氣候變遷熱逆境環境下產精性能耐熱適應力佳 種公豬檢定新方法之產業應用。精液初步檢測濃度及活力後，樣品上機分析該樣品之活 /死精子數、穿孔體及精子膜完整性、線粒體膜電位完整性與細胞凋亡比例、DNA 染色 質結構完整性及精子細胞內自由基等分析後，進行比較涼季與熱季各項精子品質參數。 將各種豬群涼季與熱季所得之平均值相減後，初步結果顯示在杜洛克品種活力下降 8.9 %、頭帽完整性下降 5%、氧化受損程度增加 1.1%﹔藍瑞斯品種為活力下降 15.4%、活 率下降 6.8%、頭帽完整性下降 6.3%、氧化受損程度增加 1.4% 及約克夏品種為活力下 降 2.7%、氧化受損程度增加 1.7%，說明熱季期間主要影響公豬精子品質參數為活力、 活率、頭帽完整性及氧化受損等項目，綜合上述結果顯示，若能將種公豬熱季期間產精 性能檢定新技術導入現代種畜禽選種之架構，引導種畜禽場培育動物以對氣候逆境（通 常是熱和乾早）的適應力及提高其耐逆境產能將其重要意義。

Hot season caused boar semen quality decrease. Therefore, ensuring the daily semen production and year-round, stable production of boar semen with superior quality become the basis for a successful reproduction scheme in pig breeding programs. The purpose of this study was to develop an evaluation and testing system of sperm quality traits for selection standards during hot season. The results showed that sperm membrane integrity, intact acrosome, oxidation degree in the Duroc, Landrance and Yorkshire pig of were decrease. Above all, the new technology of production performance verification during the breeding season can be introduced into the modern breeding system, it will be benefit to guide breeding animals to adapt to climate adversity (usually heat and drought) and improve their climate tolerance capacity.
Key Words: Boar, Heat-tolerance, Sperm quality, Testing
