A significant increase (P&lt;0.001) in the percentage of hypoosmotic positive spermatozoa was observed in CS samples. The percentage of total morphological changes in the separated samples before and after freezing was significantly lower (P&lt;0.001) compared with samples prepared using the standard procedure. A substantial decrease (P&lt;0.001) was found in the percentage of spermatozoa with damaged acrosomes. However, the percentage of spermatozoa with coiled tails was increased in the separated samples (P&lt;0.001).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Conclusions<\/jats:italic>\n                    : Column separation before freezing has a positive effect on the quality of thawed equine semen.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Potential relevance<\/jats:italic>\n                    : The quality of CS frozen\/thawed samples indicates their potential use for increasing insemination success in mares.\n                  <\/jats:p>","DOI":"10.2746\/0425164054406810","type":"journal-article","created":{"date-parts":[[2007,4,12]],"date-time":"2007-04-12T19:03:27Z","timestamp":1176404607000},"page":"43-47","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Freezability of equine semen after glass beads column separation"],"prefix":"10.1111","volume":"37","author":[{"given":"P.","family":"KLINC","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"KOSEC","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"MAJDIC","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,1,5]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"474","article-title":"Prediction of post\u2010thaw sperm motility and sperm cryosurvival rate using the pre\u2010freeze sperm parameters","volume":"78","author":"Airbarg A.","year":"1995","journal-title":"J. med.
