The proximo-medial ultrasound-guided approach for intrathecal access to the carpal canal, as described in this study, was firstly developed on ten cadaveric limbs using an undiluted ionic iodinated contrast medium. Landmarks were identified, and the access point was established. Subsequently, the technique was validated in ten horses, and its efficacy was compared with the proximo-lateral ´blind` technique. For each injection, the following was recorded: successful injection (contrast within the carpal canal), number of attempts, and whether a structure other than the carpal sheath was penetrated. The ´blind` technique had a total accuracy of 70% (7/10; 95% confidence interval [CI]: CI 35%-93%), with inadvertent injection into the dorso-palmar pouch of the radiocarpal joint, carpal canal surrounding soft tissue, and intravenous injection being the most common issues associated with this approach. In contrast, the ultrasound-guided approach achieved an accuracy of 100% (10/10; 95% confidence interval [CI]: 69%-100%) for intrasynovial administration of the contrast medium. The ultrasound-guided proximo-medial approach for injecting the carpal sheath is an accurate and technically straightforward technique. This approach should be considered for synoviocentesis of the carpal sheath, particularly in horses with no evident effusion.","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":" ","pages":"105258"},"PeriodicalIF":1.3,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142877390","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}

Our objectives were to determine the immediate and post-surgical reduction in CFU/mL on equine skin prepared with CHG-based or 70 % isopropyl alcohol (IPA)-based (without CHG) protocols in a clinical setting with arthroscopic surgery. Our hypotheses were that the log10CFU/mL reduction would not significantly differ between protocols immediately after preparation or at the end of surgery. Six horses underwent a 40 min bilateral tarsocrural joint arthroscopy with each limb randomly assigned to Group A or B. Group A tarsocrural joints underwent a rough scrub using 4 % CHG and a 5 min sterile scrub using 2 % CHG. Group B underwent a rough scrub with neutral soap followed by a 90 s sterile scrub with IPA. Samples were collected before rough scrub (T0), immediately after sterile scrub (T1), and end of surgery (T2). CFU/mL were determined in duplicate and were log-transformed and averaged. ANOVA models compared the immediate reduction (T0-T1) and sustained reduction (T0-T2) between treatment groups. The immediate and sustained log10CFU/mL reduction between groups was not different (P = 0.46, P = 0.42). Both groups achieved at least a 2-log immediate and sustained reduction. Limitations include small population size, short surgical duration, length of follow-up, and researchers were not blinded to treatment during sampling. This study demonstrates efficacy of IPA-based antisepsis, without the need for CHG, and supports further investigation in clinical surgery as an acceptable method of surgical site preparation.","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":" ","pages":"105257"},"PeriodicalIF":1.3,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142872195","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}

Certain hoof temperatures have been suggested as effective in minimizing the inflammatory process; however, there is limited evidence on which methods are best at achieving these temperatures. Our objective was to determine how different methods of cryotherapy influence the rate and extent of cooling for the equine hoof wall. Four horses received three hoof cooling treatments and a control (CON; no treatment application) in a 4 × 4 Latin square design. Treatments included (1) ice surrounding the hoof in a 5 L fluid bag with water drainage holes (DB), (2) ice surrounding the hoof in an undrained bag (UB), and (3) ice in a commercial wader boot (CW). Hoof wall temperatures were collected via thermal imaging for 12 h. Thermally imaged body temperatures and thermometer-based rectal temperatures, heat index, relative humidity, and ambient temperature were recorded. A treatment × time interaction (P < 0.001) was observed for all hoof temperatures. All treatments differed from CON after 2 h post-application, with the UB treatment resulting in the greatest and most sustained reduction in hoof temperatures over the 12 h period (a change of -23.7 °C ± 1.6). The wader boot showed similar trends to the UB treatment but was poorly tolerated by the horses. Environmental effects differed between hoof and body surface. Our findings indicate that cryotherapy treatments that maintain an ice-water slurry around the hoof result in greater decreases in hoof temperatures 2 h post-treatment compared to drained ice application.","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":" ","pages":"105255"},"PeriodicalIF":1.3,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142791747","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}

The objectives were to compare changes in subluxations, range of motion, and the pain-pressure threshold in the axial skeleton of horses fed hay with (NET) or without (CON) hay nets. In September 2021, 13 adult horses were blocked by bodyweight (BW) and randomly assigned to the NET or CON treatments for one year. After one year, horses switched treatments and the trial concluded in September 2023. Horses were housed in dry lots with free choice access to round bales with or without hay nets (4.45 cm openings). Chiropractic adjustments occurred in May and August each year to note axial skeleton subluxations. Evaluations occurred in June, July, and August to measure cervical range of motion and mechanical nociceptive thresholds (MNTs) of the jaw, poll, and withers. SAS was used and significance was set at P≤0.05. There was an average 1.6-point increase in cervical subluxations observed in NET horses (P<0.05) while no changes were observed for the TMJ and thoracic or lumbar vertebral regions (P>0.05). Average cervical range of motion was 5 degrees greater in NET horses compared to CON horses for chin to chest and chin to fetlock measurements (P≤0.05). No differences were observed in MNTs (P>0.05). These data suggest that netted round bales may only have minor impacts on the axial skeleton of horses over 12-weeks.","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":" ","pages":"105256"},"PeriodicalIF":1.3,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142791595","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}

Recent advancements, including SuperGen™ sorters and Ultraplus™ semen processing methods developed by STgenetics® (Navasota, Texas), have significantly improved the efficiency of the sex-sorting process and reduced the sperm damage previously reported. To facilitate the broader use sex-sorted semen in the equine industry, it is essential to address challenges such as shipping cooled semen to a central sorting facility, minimizing oxidative stress and DNA fragmentation, and developing effective methods for short-term cooling or long-term cryopreservation of the sex-sorted sperm. In this study, we evaluated the feasibility of shipping cooled (8 °C) equine semen to a central facility for sorting and assessed the quality of sperm post-sorting and preservation. Results from the improved process showed enhancements in sperm motility, morphology, viability and DNA fragmentation following sex-sorting. Although there was a slight, consistent increase in lipid peroxidation of sex-sorted sperm, the quality of sperm over the first 24 h post-sorting was comparable to that of conventional (non-sorted) cool-shipped semen. Fertility rates with fresh semen did not differ between conventional and sex-sorted sperm. When using frozen-thawed sex-sorted sperm for intracytoplasmic sperm injection (ICSI), consistent blastocyst production was achieved, albeit at slightly lower rates than those observed with conventional semen for the same stallions. Stallion-specific variability may account for some of these differences. Overall, sex-sorted semen used for ICSI resulted in a higher number of embryos of the desired sex compared to those obtained using conventional semen.","PeriodicalId":15798,"journal":{"name":"Journal of Equine Veterinary Science","volume":" ","pages":"105251"},"PeriodicalIF":1.3,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142791766","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}
