Lamb vaccination against echinococcosis is considered an effective method for controlling the transmission of echinococcosis in the intermediate host-sheep, thereby disrupting the disease's transmission chain, and thus a crucial strategy for preventing and controlling echinococcosis. Based on field survey data on 581 households collected from 11 counties of China's Qinghai Province, this study evaluated the impact of lamb vaccination against echinococcosis on livestock farming scale using a staggered difference-in-differences method. The results show that on average, households that received lamb vaccination from their county as part of the 'Action Plan for Echinococcosis Prevention and Control in Qinghai Province (2016-2020)' had a livestock farming scale of 52.09 heads (or 36%) higher than those that did not receive lamb vaccination. This effect likely works through reductions in cattle and sheep mortality and culling numbers. A simple accounting analysis suggested that the increase in livestock farming scale can translate into a profit of 26,500 yuan (≈3938 US dollars at 2022 prices), although this impact has a short-term lag and is limited in duration. While these findings may not apply to all livestock households in China, they suggest that developing area-specific lamb vaccination programs, increasing lamb vaccination rates, and ensuring timely vaccinations are crucial for enhancing livestock farming scale in echinococcosis endemic areas.</p>","PeriodicalId":23543,"journal":{"name":"Veterinary Medicine and Science","volume":"11 2","pages":"e70273"},"PeriodicalIF":1.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11875069/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543515","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}

The aim of this study was to analyse the effects of perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA) on boar spermatozoa during capacitation through a focus on agglutinate formation. A second objective was to assess the influence of d-penicillamine (d-Pen) on boar spermatozoa agglutinate prevention. PFOS and PFOA in sublethal concentrations reduced the proportion of spermatozoa that achieved capacitation, PFOS increased to 35% the spermatozoa mortality and both toxic compounds generated an abnormally excessive increase in rosette-type agglutinates that formed non-mobile aggregates (only vibrant), like those that form during physiological capacitation. This increase in agglutinates came at the expense of available free spermatozoa for fertilisation. Treatment with d-Pen, however, significantly reduced rosette formation by PFAS. Further study of the underlying mechanisms revealed that exposure to PFOS and PFOA led to decreased free sulfhydryl (SH) groups on the surface of the spermatozoa, likely due to oxidation caused by the PFAS. Administering d-Pen also reversed this effect, suggesting a possible involvement of S-S bond formation during spermatozoa agglutination. These findings not only shed light on how PFOS and PFOA affect boar spermatozoa capacitation, but also shows the mechanism associated with spermatozoa rosette-type agglutination provoked by PFOS and PFOA. Furthermore, they underscore the need to delve more deeply into the mechanisms that govern agglutinate formation during spermatozoa capacitation physiology to devise improved, targeted therapeutic strategies for male infertility and enhance animal reproduction.</p>","PeriodicalId":23543,"journal":{"name":"Veterinary Medicine and Science","volume":"11 2","pages":"e70244"},"PeriodicalIF":1.8,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11911929/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143650980","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}
