【摘要】 为了研究猪精子在17℃保存时不同渗透压对精子质量、畸形率的影响,试验添加不同剂量的葡萄糖控制稀释液的渗透压,用迈朗全自动精子质量检测仪检测猪精子质量指标及畸形率。结果表明:在多数项目上,无论是保存时间还是质量参数(精子活率、精子活力、路径速度等),渗透压268,368 m Osmol/kg的2,3组都明显优于渗透压183,400 m Osmol/kg的1,4组。说明猪精子在等渗和适当高渗情况下有利于保存。更多还原

【Abstract】 To study the effect of different osmotic pressures on sperm quality and deformity rate at 17 ℃,in this experiment different proportions of glucose were added to controll diluents’ osmotic pressure,and boar sperm quality and deformity rate were determined by using Mailang automatic sperm quality detector. The experimental data showed that,both the preservation time and the quality parameters( sperm motility rate,sperm motility,path velocity,etc) in group 2 and 3( with osmotic pressure of 268 and 368 m Osmol/kg respectively) were obviously better than those in group 1 and 4( with osmotic pressure of 183 and 400 m Osmol/kg each). Those results demonstrated that iso-osmotic pressure or slightly high-osmotic pressure were beneficial to the preservation of pig sperm.更多还原
