Is Tris-Egg Yolk Extender Better Than LDL Extender in Chilled Semen Preservation?
Semen preservation is the most technology used in artificial insemination and animal breeding. There are two critical types of preservation, including preservation in freezing and chilled temperature, which cause reducing in sperm quality and finally lead to a decrease in the fertilization rate. Different extenders from international commercial sources are used to dilute and preserve the sperm during comparatively expensive chilling and cryoprotection operations. Several researchers will suggest applying the lab extenders prepared for semen storage, especially in chilled technic. In general, that are two famous laboratory prepared extenders, tris egg yolk and LDL extenders; thus, they are necessary to determine which of these are better used in semen preservation at chilling temperature.
