A total of 18 ejaculates were collected, once per week, from six fertile stallions for three consecutive weeks in October and November, to compare motility over time between extenders using four semen processing treatments. Four total aliquots of semen were used. Two aliquots of each semen collection were extended in either INRA96 or an experimental proprietary milk-based extender Walworth (WW) extender, and each was designed for multi-day storage of fresh chilled semen. Each aliquot was divided again, and either centrifuged at 600 μg for 10 min without cushion, or not centrifuged and extended to a final concentration of 25 × 10^6 spermatozoa/mL. The treatments evaluated were INRA96 without centrifugation (INRA-NC) or with centrifugation (INRA-C), and Walworth extender without centrifugation (WW-NC) or with centrifugation (WW-C). Total and progressive motility were measured using Sperm Vision~ CASA at 0, 24, 48 and 72 h post-collection. Samples were stored at 4 ℃. No differences were found between extenders in progressive (P = 0.13) or total motility (P = 0.14) over the four different time points without centrifugation. However, ejaculates processed in INRA-C group had the greater total and progressive motility (P 〈 0.05) over the four time points than ejaculates in the WW-C group. It was found that centrifugation and re-suspension of stallion semen in INRA96 improved the longevity of fresh chilled semen. However, when not using centrifugation, the Walworth extender proved to be as effective for maintaining spermatozoa motility across all time points as 1NRA96 , and may be an alternative for use in the equine breeding industry.
