A total of six dogs were used in the study. The ejaculate was collected from dogs three times at different times by massage method. A total of 18 ejaculates were used and each ejaculate was divided in five experimental groups. The experimental groups were designed to tris extender containing no antioxidants control, 1\u2009\u03bcg\/mL SeNP1, 2\u2009\u03bcg\/mL SeNP2, and 1\u2009\u03bcg\/mL SS1 and 2\u2009\u03bcg\/mL SS2. Extended semen were equilibrated for 1\u2009h at 4\u00b0C, then frozen in liquid nitrogen vapour and stored in liquid nitrogen (~\u2212196\u00b0C). After thawing, semen samples were evaluated in terms of CASA motility and kinematic parameters, spermatozoa plasma membrane integrity and viability (HE Test), spermatozoa morphology (SpermBlue) and DNA fragmentation (GoldCyto). Antioxidant enzyme activity (glutathione peroxidase; GPX, superoxide dismutase; SOD, catalase; CAT) and lipid peroxidation (malondialdehyde; MDA) were evaluated in frozen\u2013thawed dog sperm. When the results were evaluated statistically, the progressive motility, VCL, and VAP kinematic parameters in the SeNP1 group were significantly higher than the control group after thawing (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). The highest ratio of plasma membrane integrity and viable spermatozoa was observed in the SeNP1 group, but there was no statistical difference found between the groups (<jats:italic>p<\/jats:italic>\u2009&gt;\u2009.05). Although the ratio of total morphological abnormality was observed to be lower in all groups to which different selenium forms were added, compared to the control group, no statistical difference was found. Spermatozoa tail abnormality was significantly lower in the SeNP1 group than in the control and SS2 group (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). The lowest ratio of fragmented DNA was observed in the SeNP1 group, but there was no statistical difference was found between the groups (<jats:italic>p<\/jats:italic>\u2009&gt;\u2009.05). Although there was no statistical difference between the groups in the evaluation of sperm antioxidant profile, the highest GPX, SOD and CAT values and the lowest lipid peroxidation values were obtained in the SeNP1 group. As a result, it was determined that 1\u2009\u03bcg\/mL dose of SeNP added to the tris\u2010based extender in dog semen was beneficial on spermatological parameters, especially sperm kinematic properties and sperm morphology, and therefore nanoparticle selenium, a nanotechnology product, made a significant contribution to the freezing of dog semen.<\/jats:p>","DOI":"10.1111\/rda.14652","type":"journal-article","created":{"date-parts":[[2024,6,24]],"date-time":"2024-06-24T07:24:34Z","timestamp":1719213874000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Investigation of the protective effects of different forms of selenium in freezing dog semen: Comparison of nanoparticle selenium and sodium selenite"],"prefix":"10.1111","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5728-1478","authenticated-orcid":false,"given":"Burcu","family":"Esin","sequence":"first","affiliation":[{"name":"Department of Animal Reproduction and Artificial Insemination University of Ondokuz Mayis  Samsun Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cumali","family":"Kaya","sequence":"additional","affiliation":[{"name":"Department of Animal Reproduction and Artificial Insemination University of Ondokuz Mayis  Samsun Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melih","family":"Akar","sequence":"additional","affiliation":[{"name":"Department of Production Animal Medicine, Faculty of Veterinary Medicine University of Helsinki  Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mesut","family":"\u00c7evik","sequence":"additional","affiliation":[{"name":"Department of Animal Reproduction and Artificial Insemination University of Ondokuz Mayis  Samsun Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,6,24]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.anireprosci.2014.01.009"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.nano.2013.10.011"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0093\u2010691X(01)00562\u20103"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1080\/10408398.2022.2101093"},{"issue":"4","key":"e_1_2_9_6_1","first-page":"263","article-title":"Effects of in\u00a0vitro selenium addition to the semen extender on the spermatozoa characteristics before and after freezing in water buffaloes (Bubalus bubalis)","volume":"3","author":"Dorostkar K.","year":"2012","journal-title":"Veterinary Research Forum"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1939\u20104640.2002.tb02599.x"},{"key":"e_1_2_9_8_1","unstructured":"Forsberg L.
