Semen characteristics of Chinese Fengjing, CHinese Meishan and American Yorkshire boars were examined. Samples were collected from 24 boars: 6 Fengjing, 12 Meishan and 6 Yorkshire. Three semen characteristics and 6 biochemical evaluations of semen or seminal plasma were analyzed. The whole semen parameters measured were gelatinous (gel) and gel-free volume and progressive motility. Fengjing boars were higher in gel volume than Meishan (P < 0.05) but not Yorkshire boars (P > 0.25), while Yorkshire boars were higher than Meishan boars in gel volume (P < 0.10). The gel-free volume was higher in Yorkshire and Fengjing boars than Meishan boars (P < 0.10), but Fengjing gel-free volumes did not differ from Yorkshire gel-free volumes (P > 0.80). However, the only difference detected for progressive motility was between Fengjing and Meishan boars (78.5 vs 74.5%; P < 0.10). Sperm concentration was higher in Meishan than Yorkshire boars (P < 0.01) although these breeds did not differ from Fengjing boars (P > 0.18). The biochemical messurements made were fructose, galactose, inositol, total carbohydrate and total protein in seminal plasma and pH in gel-free semen. Fengjing boars had higher concentrations of galactose in seminal plasma than Meishan or Yorkshire boars (P < 0.05), while Meishan seminal plasma had higher galactose concentrations than Yorkshire seminal plasma (P < 0.10). Fructose, inositol and total carbohydrate concentrations were all higher in Fengjing and Meishan seminal plasma than Yorkshire seminal plasma (P < 0.05). Fengjing seminal plasma had higher levels of inositol than Meishan seminal plasma (769 vs 566 mg/100 ml; P < 0.10). Furthermore, Fengjing and Meishan semen had similar fructose and total carbohydrate concentrations (P > 0.80). The pH level and total protein concentration did not differ among the 3 breeds (P > 0.30). This study indicated that breed differences were detected for several seminal parameters, although no single breed had consistantly higher values for all the parameters measured.
对中国枫泾猪、中国梅山猪和美国约克夏猪的精液特性进行了检测。从24头公猪采集样本：6头枫泾猪、12头梅山猪和6头约克夏猪。分析了三项精液特性以及精液或精浆的六项生化指标。所测量的全精液参数有胶冻状（凝胶）体积、无胶冻体积和直线运动率。枫泾公猪的凝胶体积高于梅山公猪（P < 0.05），但与约克夏公猪相比无差异（P > 0.25），而约克夏公猪的凝胶体积高于梅山公猪（P < 0.10）。约克夏公猪和枫泾公猪的无胶冻体积高于梅山公猪（P < 0.10），但枫泾公猪的无胶冻体积与约克夏公猪的无胶冻体积无差异（P > 0.80）。然而，在直线运动率方面检测到的唯一差异存在于枫泾公猪和梅山公猪之间（78.5%对74.5%；P < 0.10）。梅山公猪的精子浓度高于约克夏公猪（P < 0.01），不过这两个品种与枫泾公猪相比无差异（P > 0.18）。所进行的生化检测指标包括精浆中的果糖、半乳糖、肌醇、总碳水化合物、总蛋白以及无胶冻精液的pH值。枫泾公猪精浆中的半乳糖浓度高于梅山公猪或约克夏公猪（P < 0.05），而梅山精浆中的半乳糖浓度高于约克夏精浆（P < 0.10）。枫泾和梅山精浆中的果糖、肌醇和总碳水化合物浓度均高于约克夏精浆（P < 0.05）。枫泾精浆中的肌醇水平高于梅山精浆（769对566毫克/100毫升；P < 0.10）。此外，枫泾和梅山精液中的果糖和总碳水化合物浓度相似（P > 0.80）。三个品种之间的pH值水平和总蛋白浓度无差异（P > 0.30）。本研究表明，在几个精液参数方面检测到了品种差异，尽管没有一个品种在所有测量参数上的值始终更高。
