Abstract

The aim of the present study was to evaluate the effects of administration of PGF2α on semen characteristics in crossbred rams in the non-breeding season. Twenty crossbred rams (Arkhar-Merino × Moghani and Arkhar-Merino × Ghezel) were randomly allocated into two equal groups. The experimental group received 7.5 mg IM of Estroplan (PGF2α analogue) and the control group received 1 ml of water soluble. A total number of eighteen ejaculates per ram were collected by artificial vagina twice a week 30 min following IM administration. Semen ejaculates were evaluated for volume, sperm concentration, total sperm output, mass and individual motility, methylene blue reduction time-test (MBRT), percentage of live sperm and sperm abnormality rates. The results of the current study shows that PGF2α treatment on crossbreed rams improved most semen characteristics including volume, sperm concentration, total sperm output and MBRT in comparison to control group (P < 0.01). However, other semen characteristics show similar values. We concluded that PGF2α actually improved semen output without any negative effect on sperm qualities.

前列腺素f2 α处理对非繁殖期杂交公羊精液特性的影响

本研究旨在评价非繁殖期给药PGF2α对杂交公羊精液特性的影响。选用20只杂交公羊(阿卡-美利奴×莫加尼和阿卡-美利奴×格泽尔)，随机分为两组。实验组给予雌二醇(PGF2α类似物)7.5 mg IM，对照组给予水溶性雌二醇1 ml。每公羊共18次射精，每星期两次，在注射后30分钟通过人工阴道收集。评估精液的体积、精子浓度、精子总量、质量和个体活力、亚甲基蓝还原时间测试(MBRT)、活精子百分比和精子异常率。本研究结果表明，与对照组相比，PGF2α处理提高了杂交公羊精液体积、精子浓度、总精子量和MBRT的大部分性状(P < 0.01)。然而，精液的其他特征也显示出类似的价值。我们得出结论，PGF2α实际上提高了精液输出，而对精子质量没有任何负面影响。
