E-Z Freezin®-"LE" and E-Z Freezin® -"MFR5" extenders are  recommended for equine frozen semen breeding programs.The "LE" version is a Lactose EDTA formula and the "MFR5" is a Modified French formula.  Both of these extenders contain the antibiotic Ticarcillin.

While the conventional methods for freezing stallion semen suggested that E-Z Freezin®-"LE" should be processed at room temperature and E-Z Freezin®-"MFR5" should be cooled to 5
º C prior to packaging, recent studies have shown that both methods can be used with these extenders.  In general, pre-cooling to 5º C is beneficial for most stallions but is not required. 

All E-Z Freezin® extenders are sold in packs of five 15 ml hermetically sealed, foil-lined packets.  All E-Z Freezin® extender lots are evaluated prior to sale by the Colorado State University Animal Reproduction and Biotechnology Laboratory to ensure a superior quality product.

E-Z Freezin® -"LE" is now available in 5-packs with no additional dry ice / blue-ice packaging fee.
