Zusammenfassung:This study was designed to evaluate the effect of adding the detergent Equex-STM to the extender used to dilute semen for cryopreservation on several indicators of sperm preservation. Two consecutive ejaculates per day were obtained from 5 Assaf sheep on two days out of every week over three alternate months. The freezing protocol involved diluting the semen in Fiser's extender, to which 0.7 % Equex-STM was added or omitted before cryopreserving the semen in straws by exposure to nitrogen vapor. Equex-STM supplementation gave rise to significantly (p
