The study was conducted to determine the effect of 7-dehydrocholesterol loaded cyclodextrin (7-DHCLC) and cholesterol-loaded cyclodextrin (CLC) on changes of bull sperm motility during short term storage (+4 degrees C). Collected ejaculates were pooled and divided into 7 groups, as following one control (C); three 7-DHCLC and the other three CLC concentrations. Diluted semen samples were transferred and stored at +4 degrees C and sperm motility was analysed in determined intervals during three days storage period with computer aided sperm analyse (CASA) system. Motility decreased in all groups; however, 7-DHCLC and CLC groups motility decreased in the next two days gradually. But, CLC 1.5 mg/120x10(6) group were identified as the best groups for protecting motility in short time preservation. In conclusion, adding different rates of 7-DHCLC and CLC to semen extender preserved motility for three days in bull semen stored at +4 degrees C.
