摘要: 本试验目的是研究稀释液中添加不同浓度的棉子糖对冻融后绵羊精液品质的影响。选用10只健康乌珠穆沁种公羊,采集精液经检验合格在37 ℃下混匀,精液样品平均分成5份,用含有0、5、10、15、20 mmol/L的不同浓度棉子糖稀释液稀释。采用0.25 mL细管法冷冻,将冷冻后的细管精液置于37 ℃水浴锅中解冻15 s后进行相关指标评价及酶(SOD、GSH、MDA、GSH-Px和CAT)的测定。结果表明,当棉子糖的添加量为15 mmol/L时精子活率显著高于对照组(P<0.05),畸形率显著低于对照组(P<0.05),弯尾率显著高于对照组(P<0.05),SOD活力显著提高(P<0.05),MDA也显著低于对照组(P<0.05)。

Abstract: The aim of the present study was to determine the effects of different doses of raffinose on post-thawed sheep spermatozoa quality. Ejaculates collected from 10 healthy Ujumqin sheeps were evaluated and pooled at 37 ℃. Semen samples were divided equally into 5 groups, then diluted with 0, 5, 10, 15, 20 mmol/L of different concentrations of raffinose and frozen in 0.25 mL French straws. Frozen straws were thawed individually at 37 ℃ for 15 s in a water bath for microscopic evaluation and then detected the activity of SOD, GSH, MDA, GSH-Px and CAT. The results showed that, compared to the control groups, when the addition of raffinose was 15 mmol/L, sperm motilities were increased significantly (P<0.05), abnormal sperm rate was decreased significantly (P<0.05), host rate was increased significantly (P<0.05), the enzyme activity of SOD significantly improved (P<0.05), MDA was decreased significantly (P<0.05).
