Low density lipoproteins added to an extender frozen or lyophilized are evenly efficient in cryoprotecting ovine sperm cells than when 16% whole egg yolk was added

Low density lipoproteins added to an extender frozen or lyophilized are evenly efficient in cryoprotecting ovine sperm cells than when 16% whole egg yolk was added

The aim of this study was to test different concentrations of low density lipoprotein (LDL) in replacement of whole egg yolk in extenders preserved in the aqueous or lyophilized form, for ram sperm cryopreservation using two cooling curves (-40°C/min from 5 to –140°C and nitrogen vapor). One ejacul...
