The heat stress indices were calculated by the equation: THI= [0.8 x (EnTemp + RH/100)] x [(EnTemp – 14.4) + 46.4]. In contrast, systolic/diastolic testicular blood flow velocities, motility, and vigor were greater in winter (33.3 ± 9.3 cm/s; 5.9 ± 2.2 cm/s; 81.2 ± 8.5 %; 3.2 ± 0.4) than in summer (24.4 ± 6.7 cm/s; 4.0 ± 1.0 cm/s; 64.2 ± 21 %; 2.7 ± 0.6). Significant correlations were found between thermal comfort indices and seminal traits in summer, and between Doppler/thermographic data and semen quality in winter.</div></div><div><h3>Conclusion</h3><div>The analyzed indices characterized thermal, circulatory, and seminal parameters in stallions, highlighting seasonal differences and correlations, and supporting the use of Doppler ultrasonography and infrared thermography in fertility assessment, thermal comfort, and optimal breeding season selection.</div></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":"151 ","pages":"Article 105615"},"PeriodicalIF":1.3,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144180013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
