Traditional treatments, including antibiotics and hormonal therapies, often show limited effectiveness and raise concerns about resistance and animal health. Mesenchymal stem cells (MSCs) offer a promising alternative because of their ability to regenerate tissues, modulate immune responses, and improve reproductive function. This review summarizes recent studies and consolidates emerging preclinical and clinical insights into MSC-based reproductive therapy in cattle. MSCs help repair ovarian and uterine tissues by migrating to damaged areas, reducing inflammation, releasing growth factors, and protecting against oxidative stress. Different methods of therapy, such as intrauterine infusion, intravenous delivery, and intraovarian injection, have been tested with encouraging results. For example, MSC therapy has improved pregnancy rates in cattle with endometritis and restored ovarian activity in animals with cystic ovaries. In addition to cell-based therapies, MSC-derived secretomes and exosomes demonstrate strong potential as cell-free approaches, offering regenerative effects with reduced risks. Despite these advances, challenges remain in translating MSC therapy to clinical practice. Variability in outcomes, technical expertise required for administration, and regulatory approval are major barriers. More studies are needed to standardize treatment protocols, evaluate long-term safety, and develop cost-effective strategies. Overall, MSC therapy represents a novel and sustainable approach for improving cattle fertility and herd productivity, offering an important step forward in veterinary reproductive biotechnology.</p>","PeriodicalId":23587,"journal":{"name":"Veterinary World","volume":"18 9","pages":"2888-2899"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12535447/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145329873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PCU analyses revealed uneven intensity of AM use, with Spain and Poland showing high usage rates, while Germany and France demonstrated more efficient use. During the progress period, 20 MS were rated as strong contributors, while three MS showed limited contributions. For the target period (2023-2030), only six MS (e.g., Italy, Romania, Latvia, and Malta) are projected to maintain strong contributions, whereas seven MS, including Poland, Lithuania, and Denmark, are unlikely to achieve the target.</p><p><strong>Conclusion: </strong>The EU-27 achieved substantial reductions in AM sales during 2018-2022, yet performance remains uneven across MS. While some countries have already met or are close to the 2030 target, others require accelerated policy interventions, veterinary stewardship, and stronger CAP alignment. Achieving the EU-wide 50% reduction by 2030 will depend heavily on high-consumption MS adopting best practices from leading countries.</p>","PeriodicalId":23587,"journal":{"name":"Veterinary World","volume":"18 9","pages":"2746-2760"},"PeriodicalIF":2.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12535452/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145330228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
{"title":"Efficacy and sterilization resilience of silicone rubber bands as an alternative to suture ligation in feline orchiectomy.","authors":"Natnaree Raekriang, Panpicha Sattasathuchana, Naris Thengchaisri","doi":"10.14202/vetworld.2025.2553-2562","DOIUrl":"10.14202/vetworld.2025.2553-2562","url":null,"abstract":"<p><strong>Background and aim: </strong>Suture ligation is the standard technique for feline orchiectomy, but it requires surgical expertise and is time-consuming. Silicone rubber bands (SRBs), previously used in human procedures, offer a potential alternative. This study aimed to (1) evaluate the effects of common veterinary sterilization methods on the mechanical integrity of SRBs and (2) compare the surgical outcomes of SRB versus suture ligation in feline orchiectomy.</p><p><strong>Materials and methods: </strong>Twenty-eight: SRBs were randomly assigned to four sterilization groups: No sterilization (control), 2% chlorhexidine gluconate, autoclaving, and hydrogen peroxide gas plasma. Bands were tested for ultimate tensile strength (UTS), elongation at break, and elastic modulus using a universal testing machine. Separately, 20 healthy male cats were randomly assigned to undergo orchiectomy using either SRB ligation (n = 10) or traditional suture ligation (n = 10). Surgical time, intraoperative/post-operative complications, Glasgow composite measure pain scale scores, wound healing, and gastrointestinal (GI) symptoms were monitored for 10 days.</p><p><strong>Results: </strong>Hydrogen peroxide gas plasma sterilization preserved SRB elasticity without significantly affecting UTS, while autoclaving and chlorhexidine treatment increased stiffness and reduced elongation at break (p < 0.05). SRB ligation significantly reduced surgical time (3.06 ± 0.32 min) compared to suture ligation (4.48 ± 0.62 min; p < 0.01). There were no significant differences in post-operative pain scores, wound healing characteristics, or complication rates between groups (p > 0.05). Mild GI symptoms were observed in both groups but were not statistically different.</p><p><strong>Conclusion: </strong>SRB ligation is a viable, time-efficient, and clinically comparable alternative to traditional suture ligation in feline orchiectomy. Hydrogen peroxide gas plasma is recommended for SRB sterilization due to its minimal impact on material integrity. This technique may be especially beneficial in high-volume or resource-limited settings, offering a safe, efficient approach to feline population control. Future research should evaluate the long-term biocompatibility and broader surgical applications of SRBs in veterinary practice.</p>","PeriodicalId":23587,"journal":{"name":"Veterinary World","volume":"18 8","pages":"2553-2562"},"PeriodicalIF":2.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12501543/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145253146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
