中文摘要 | 本調查為比較藍瑞斯(L.),杜洛克(J.),大白豬(W.),比利華(P.),明尼蘇達二號(M.),漢布夏(H.)和雜種公豬(LJ)等品種公豬之精液量、品質及其生育力。受調查公豬之月齡在12~40之間。 首次調查時,每頭公豬逢機抽檢三次精液樣品,公豬之採精日距5~8日,第二次調查則每頭抽檢二次精液樣品,授精日距為5日;調查之項目包括:精液量(濾除膠體部),在37~38℃溫度之精蟲活力,精蟲濃度;一次射精之總精蟲數;畸型精蟲率,精液之pH值與在調查期間公豬授精之受胎率。經分析結果如次: (一)所調查之大部分項目,在同品種內公豬個體間有很大之變異範圍存在。 (二)據兩次調查受胎率資料分析結果,各品種間之差異均不顯著(p>0.05)。 (三)首次調查之精液量,品種間有顯著差異(p<0.01),其中以L.之精液量最多(225 ml.),J最少(136 ml.)。而第二次調查時,品種間之差異則不顯著(p>0.05)。 (四)畸型精蟲率在二次調查時,品種間有差異意義(p<0.05),各為W. 33%,L. 13.9%,H. 7.8%,J. 6.5%。 (五)H. 精液之pH值(7.08)分別顯著地低於L.(7.42) 或J.(7.32)。 (六)其他各項在品種間之差異均不顯著。 |
英文摘要 | A comparison has been made of the quantity, quanlity & fertility of semen from Landrace (L.), Duroc Jersey (J), Large White (W), Pietrain (P), Minnesota No. 2 (M), Hampshire (H), and crossbred (LJ) boars of 12 to 40 months of age. In the first part 3 samples of semen were collected at intervals of 5-8 days, and in the second, two samples 5 days apart. The measurements made included semen volume (excluding gelatinous portion), motility at 37-38℃, sperm concentration, total sperm per ejaculation, abnormal sperm percentage, pH, and the conception rate of sows artificially inseminated. 1. There were very great differences between boars within all breeds in most of the measurements made. 2. In the first part there were significant difference between breeds in semen volume, which was greatest (225 ml) in L and least (136 ml) in J boars. In the second part, breed differences were not significant. 3. In the second part, but not in the first, there were significant differences between breeds in the percentage of abnormal sperms, 33% in W, 13.9% in L. 7.8% in H and 6.5% in J boars. 4. The pH of H semen (7.08) was significantly lower than that of L (7.42) or J (7.32). 5. In other respects, differences between breeds were not significant. |
