Blood was collected from eight horses (mean age ± SD = 16 ± 2.7 years; range = 13 - 21 years) at 10 and 5 min prior to treatment or control administration, just prior to the subsequent SRT, directly after the SRT, and at 60- and 90-min post SRT.

Data were analyzed by two-way repeated-measures ANOVA. For plasma pH, Na<sup>+</sup>, K<sup>+</sup>, Cl<sup>-</sup>, Lac<sup>-</sup>, SID, insulin and glucose, no effects of treatment or treatment by sampling-timepoint interaction were found (p>0.05). Plasma tCO<sub>2</sub>, Ca<sup>++</sup>, pH, Na<sup>+</sup>, SID, and glucose concentrations were significantly lower, and Lac<sup>-</sup> was significantly higher, directly after the SRT compared to all other timepoints (p<0.05).

For turf racecourses in Britain, the ground is descriptively classified and numerically quantified on the morning of a race meeting by the clerk of the course and subsequently published to assist decision making. Importantly, this includes deciding whether a horse should or should not run. The going is also assessed and classified during the meeting by racing analysts using the normalized winning times from each race result. Differences between going assessments are regularly reported, therefore this study aimed to evaluate whether an alternative method of measuring going could better predict going measured from performances. Measurement and performance data from 25 flat and 25 jump meetings were compared using linear and nonlinear regression models. A continuous two-phase polynomial model for cushioning was found to be the best predictor of performance going for all 50 meetings (adjusted <em>r<sup>2</sup></em>=0.819, <em>P</em><0.001). As cushioning can provide a going related indicator of the forces that the horse will experience at gallop, this measurement may be useful when evaluating racecourse going. This initial model suggests that there is little performance advantage at maximal galloping speeds above a cushioning value of approximately10 kN, possibly due to changes in limb contact timings to manage limb forces limits as the ground becomes firmer. An expansion of objective measurements of going that relate to performance across a wider geographic region, if not internationally are needed to confirm this limit.</div></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":"143 ","pages":"Article 105211"},"PeriodicalIF":1.3,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142501720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each pony underwent the same research-focused lunging program on a lunge line and, subsequently, in a round pen with a two-day interval between sessions.

These changes in guidelines allowed for registration of any horse with a palomino body color, including those with unknown pedigrees. While this promoted registry growth, documenting the breed's orgins from those known pedigrees making up the breed's foundation is important with the introduction of unknown pedigrees. This can be accomplished using pedigree tracing, which is of particular value for color registries as the study of coat color patterns is plagued with misunderstandings due to pedigrees with inaccurate color designations. Thus, the objective of this study was to develop an understanding of the historical origins of the modern PHBA stock-type horse through pedigree tracing. Horses (n = 460) were randomly sampled from published entries from 10 years (2012-2022) of the PHBA World Show Championship Horse Show. The All-Breed Database was utilized to obtain documentation of extended pedigrees that included uninterrupted generation-to-generation inheritance patterns of a <em>cream</em> dilution allele-influenced coat color. Pedigrees were traced back to the earliest recorded relative. We observed six foundation sires contributed to the modern PHBA stock-type horse with the majority (58%) tracing back to a sire named Old Fred. Two identified sires, Yellow Jacket (4%) and Cotton Eyed Joe (3%), have conflicts concerning color designation. While these results assist in documenting the breed's origins, genetic testing is required to accurately identify the <em>cream</em> dilution allele within the horses registered to ensure a phenotype-based solely on the <em>cream</em> dilution allele.</div></div>","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":"143 ","pages":"Article 105209"},"PeriodicalIF":1.3,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142390974","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}

In this study, CPT1A expression was comparatively addressed in 25 equine sarcoids and 5 normal skin samples using immunohistochemistry (IHC).
