E-Z Freezin®-"LE" extender is recommended for equine frozen semen breeding programs.The original "LE" version is a Lactose EDTA formula that contains the cryoprotectant glycerol and Ticarcillin as a preservative.
E-Z Freezin®-"LE" can be processed at room temperature or cooled to 5° C prior to freezing. Recent studies have shown that both methods can be used with these extenders. In general, pre-cooling to 5° C prior to freezing is beneficial for most stallions but is not required.
E-Z Freezin® extenders are packaged in 15 ml hermetically sealed packets and sold in 5-packs containing a total volume of 75 ml. All ARS extenders are evaluated by the Colorado State University Animal Reproduction and Biotechnology Laboratory to ensure a superior quality product.
E-Z Freezin® Semen Extenders may be stored frozen for two to three years in a non-frost free freezer before use.
Now shipped on a combination of dry-ice and ice packs allowing two day shipping year round. During the cooler months, three day or ground shipping is possible at the customers discretion. Contact ARS for details.
