The influences of loading cholesterol into stallion spermatozoa membranes prior to cold storage or cryopreservation were determined using cholesterol loaded cyclodextrin (CLC) before preservation, followed by the unloading of cholesterol after preservation using methyl beta cyclodextrin (MBCD). Experiment I: dose response trials determining optimal amounts of CLC and MBCD based on percentages of progressively motile spermatozoa (PMS) following preservation. Experiment II: influences of CLC and MBCD on PMS, the percentages of live intact (LI) and live non-intact (LNI) spermatozoa following cold storage. Experiment III: influences of CLC before cryopreservation and MBCD on PMS, LI, and LNI post-thaw. Addition of CLC improved (P<0.05) PMS and LI following preservation when compared to the control. Unloading cholesterol using MBCD does not alter PMS, LI nor LNI. Addition of CLC is beneficial to survival of spermatozoa following preservation and addition of MBCD in small amounts does not negatively influence PMS, LI or LNI.
