Each cow in each season was artificial insemination (AI) using sexed frozen semen and conventional semen. Frozen semen was evaluated for post-thawing motility (PTM), cell membrane integrity, and acrosome damage before synchronization using 5 ml PGF2\u03b1 plus vitamin E. Using a visual gun, we identified cows in estrus on days 4\u20137 post-synchronization. Pregnancy of cows was detected using N5Vet ultrasound on days 35 and 55. The interaction between season, semen type, and fertilization level was analyzed using standard error and two-way ANOVA, assisted by SPSS 21 software. \nResults: The wet season Temperature-Humidity Index (THI) level averaged 77.12 \u00b1 1.19, and the summer season THI level averaged 82.67 \u00b1 1.25. PTM quality averaged 60%\u201365%, viability 61%\u2013 71%, sperm membrane integrity 62%\u201365%, and acrosome integrity 88%\u201391%. Conception rates (CR) value of rainy season (p &lt; 0.05) with summer season. In addition, the services per conception (S\/C) value in the rainy season (p &gt; 0.05) is the same as in the summer. This study\u2019s S\/C and CR values were within normal limits, and the pregnancy rate reached 65%\u201386%. Pregnancy detection can be observed on day 35, and the fetal heartbeat is visible. \nConclusion: Post-AI fertilization using conventional semen was better in all seasons. The double dose of sexed semen can increase the fertilization rate in summer.<\/jats:p>","DOI":"10.5455\/javar.2024.k845","type":"journal-article","created":{"date-parts":[[2025,2,3]],"date-time":"2025-02-03T19:17:01Z","timestamp":1738610221000},"page":"1","source":"Crossref","is-referenced-by-count":0,"title":["Fertilization rate of crossbreeding cattle using sexing and conventional semen in different seasons in South Papua"],"prefix":"10.5455","author":[{"given":"Nurcholis","family":"Nurcholis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lilik","family":"Sumaryanti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Apri","family":"Irianto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Syetiel","family":"Salamony","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3407","container-title":["Journal of Advanced Veterinary and Animal Research"],"original-title":[],"link":[{"URL":"https:\/\/www.ejmanager.com\/mnstemps\/39\/39-1724546245_TYP.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T18:02:30Z","timestamp":1791482550000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ejmanager.com\/mnstemps\/39\/39-1724546245.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025]]},"references-count":0,"journal-issue":{"issue":"0","published-print":{"date-parts":[[2025]]}},"URL":"https:\/\/doi.org\/10.5455\/javar.2024.k845","relation":{},"ISSN":["2311-7710"],"issn-type":[{"value":"2311-7710","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025]]}}}
