The decision tree merges algorithmic (based on cell count results) and cultural (based on milk sample findings) approaches.During a two-year project period (August 2021-September 2023), ST was carried out on 19 dairy farms in southern Germany according to the decision tree, without specific requirements being placed on the herd's udder health before the start. A total of 1,369 dry-off observations were recorded. The dry-off cases were evaluated regarding implementation of the recommendations, cell count at the first milk recording after calving, proportion of new infections and cures during the dry period depending on the implementation of the dry-off recommendation and the udder health status of the herd.Across all farms, 38.4% of cows were dried off without the use of an antibiotic. The potential for saving antibiotics varied greatly between farms (range: 2.4-71.3%). In 75.9% of cases, a dry-off recommendation could be made based on the available udder health data; only in around 25% of cows did the dry-off recommendation require a microbiological examination of quarter milk samples. On average, the milk cell count after the dry period was less than 100,000 cells/ml in animals that were dried off with and without an antibiotic dry-off preparation. The proportions of new infections and cures during the dry period did not differ significantly between animals with and without an antibiotic dry-off preparation.The results show that with the help of the developed decision tree, ST can be carried out safely in dairy farms without endangering udder health.

{"title":"[Statement on the efficacy and immunological safety of EHV vaccines in horses].","authors":"","doi":"10.1055/a-2518-1976","DOIUrl":"10.1055/a-2518-1976","url":null,"abstract":"&lt;p&gt;&lt;p&gt;In February 2021, a serious EHV-1 outbreak occurred at an international jumping competition in Valencia, with several subsequent outbreaks in various European countries. As a consequence, several equestrian associations introduced compulsory vaccination against EHV-1, and in the immediate aftermath of the outbreak, demand for EHV vaccinations increased sharply. The initial concern has now dissipated. One equestrian association has abolished the compulsory vaccination that had only been introduced a year before, and a general debate began questioning the efficacy and safety of EHV-vaccines. This discussion has been fueled by international meta-studies that systematically re-evaluated published efficacy studies on EHV-vaccines. The meta-studies applied evidence criteria that were originally designed for preclinical studies in human medicine. It was concluded that the quality of the published data was not sufficient to prove the efficacy of EHV vaccines. Naturally, lack of evidence does not prove the opposite! Hence, one of the two author teams of these meta-studies upholds the notion that vaccination is a centerpiece of comprehensive EHV management strategies.StIKo Vet has carefully followed the discussions and the meta-studies. It cannot be expected that other infection studies on horses meeting the evidence criteria will be conducted in the near future, as EHV infection studies on horses pose considerable ethical, logistical and economic challenges. Therefore, StIKo Vet has undertaken an own re-evaluation of the existing efficacy studies. In addition, outbreak investigations were reviewed with regard to the role of EHV vaccination as a risk factor for the development of severe clinical courses.StIKo Vet concludes that, even if vaccination against EHV-1 does not confer absolute protection to the vaccinated individual, the re-evaluated studies show highly significant differences between vaccinated and unvaccinated animals: Vaccination reduces the severity of clinical symptoms and the duration and level of virus excretion. Herd vaccination can reduce overall viral loads and thus interrupt infection chains. There is ample reason to assume vaccine efficacy, but no compelling evidence was found for a correlation between EHV vaccination and severe EHV symptoms. By contrast, a comprehensive analysis of several different outbreaks shows that a herd immunity over 40 % is able to significantly reduce the risk for neurological symptoms. In addition, it has to be emphasized that the safety and efficacy of EHV-vaccines is stringently evaluated during the marketing authorization process. Only facts that have appropriately been proven in licensing studies are documented in the summary of product characteristics, e.g. the packaging leaflet. StIKo Vet therefore upholds EHV as a core-vaccination for horses. Every horse should be vaccinated and protected against EHV-1 at all times. It is likewise clear that with high viral loads and additional predisposing fac","PeriodicalId":23115,"journal":{"name":"Tieraerztliche Praxis Ausgabe Grosstiere Nutztiere","volume":"53 1","pages":"39-48"},"PeriodicalIF":0.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143450290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
