Semen collection management is affected on semen quality of bulls. The objective of this study was to compare time interval of semen collection on fresh and frozen-thawed semen quality. The semen was collected from six Holstein Friesian bulls and Charolais bulls by using artificial vagina. The whole semen was divided into 2 groups; group 1: 5-day collection interval and group 2: 2-day collection interval. The fresh and frozen-thawed semen were evaluated the semen quality under microscopic examination. The results of fresh semen had shown that 5-day collection interval group had significant higher semen volume and concentration than 2-day collection interval group (P<0.01). Furthermore, the semen qualities of frozen-thawed semen had shown that 5-day collection interval group had functional membrane integrity better than 2-day collection interval group (P<0.01). In conclusion, a long-time semen collection interval might be better with respect to semen volume, semen concentration and functional integrity of sperm membrane than that a short-time semen collection interval.
