Comparisons of some extenders have been made but there is need for further research in this area. Extenders tested included EZ Mixin (Animal Reproduction Systems, Chino, CA), Kenney's, Universal (NASCO, Fort Atkinson, WI), EquiPro, EquiPro CellGuard (Minitube of America, Verona, WI), and INRA 96 (IMV, Maple Grove, MN). Semen was collected and each ejaculate was divided and extended in each of the aforementioned extenders and stored at 4°C. Motility measures were determined using computer-assisted sperm analysis at 0, 24, 48, and 72 hours after collection. Samples were evaluated for total motility, progressive motility (PM), straight-line velocity, curvilinear velocity, straight-line distance, and curvilinear distance. Total motility and PM decreased over time in storage (P}, number={4}, journal={JOURNAL OF EQUINE VETERINARY SCIENCE}, author={LeFrapper, L. and Walston, L. and Whisnant, C.
