Early PA selection is difficult due to unreliable performance estimations. This study investigated the usefulness of genomic markers previously linked to morphological and functional traits as a tool for the early selection of PA. To this, we genotyped 520 PA and 30 TB horses using the Equine GGPArray (Illumina, n = 71,778 SNPs). Analyses included a genetic characterization of six genetic markers associated with behavioral (<em>DRD4</em>), muscular development (<em>MSTN</em>), and body size (<em>LCORL, HMGA6, ZFAT,</em> and <em>LASP1</em>) genes. Genetic differences in the <em>DRD4, MSTN,</em> and <em>LCORL</em> SNP were found between the two breeds, in the last two F<sub>ST</sub> index between breeds was 0.13 and 0.6, respectively (<em>p</em> &lt; 0.01). In DRD4, G allele was the more prevalent in PA (0.56 vs 0.45 in TB, <em>p</em> &lt; 0.05), but no differences were observed between the genotypes associated with phenotypes. In <em>MSTN,</em> heterozygous genotypes were the most common in PA (48 %), with a significant decrease in AA (Hardy-Weinberg <em>p</em> &lt; 0.05), suggesting a negative selection against it in polo horses. In body size, <em>HMGA2</em> was monomorphic in all horses, while <em>ZFAT</em> and <em>LASP1</em> SNP showed higher variability. Interestingly, 99 % of PA showed a TT genotype in <em>LCORL</em> (only 66 % in TB), demonstrating selection for smaller horses. Our results suggest that empirical selection in PA has generated an incipient genomic differentiation in discrete traits which could be used as a marker-assisted selection tool for early selection of polo horses.</p></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":"138 ","pages":"Article 105098"},"PeriodicalIF":1.3,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141065735","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}

While the benefits of equine interaction have been reported, the impact of short-term equine interaction on coping skills valuable for managing test anxiety have yet to be studied. Therefore, the purpose of this preliminary study was to evaluate the impact of short-term equine interaction during the college examination period on development of coping skills and anxiety levels associated with testing, both self-reported and those reflected in physiological measures. Full-time college students engaged in a one-hour equine interaction session held on campus at the onset of final exam week. Participants completed a survey targeting perception of anxiety levels and coping skills. Heart rate and salivary cortisol measurements were collected pre- and post-session. Paired t-tests were performed between pre- and post- session measures and correlations between survey answers and physiological measures determined. Significant reductions were found in all areas of anxiety (Overall Academics <em>P</em> = 0.0003, Final Exam Preparation <em>P</em> = 0.0003, Taking Final Exam <em>P</em> = 0.0003). The reduction in exam-related anxiety was positively correlated to cortisol concentrations (<em>r</em> = 0.69, <em>P</em> = 0.03) with lower concentrations (<em>P</em> = 0.05) and increased heart rate (<em>P</em> = 0.003) post-session. Regarding coping skills, improvements were observed post-session in assertiveness (<em>P</em> = 0.008). Skill development coupled with reduced anxiety supports the potential benefits short-term equine interaction can offer students during the high stress periods, but these findings should be confirmed with more in-depth study.</p></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":"137 ","pages":"Article 105091"},"PeriodicalIF":1.3,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140891917","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}
