The purpose of this article is to provide an overview of previous study results on serum and milk HP related to diseases in early lactation with special consideration of udder health. During inflammatory diseases of the reproductive tract, metabolism and musculoskeletal system, HP increases in the serum and may serve as a non-specific indicator for diseases during early lactation. Threshold values are available for the differentiation of healthy from diseased animals. A correlation exists between HP in blood and milk. The HP concentration in milk is not only influenced by systemic disorders, as the udder epithelium is also independently capable of synthesizing HP in case of an infection. In mastitis, HP concentration may be used to estimate the severity of the disease. In addition, HP may provide certain suspicions regarding the causative pathogen. Threshold values for milk HP are available for the differentiation of healthy individuals from subclinically resp. clinically affected animals.</p>","PeriodicalId":23115,"journal":{"name":"Tieraerztliche Praxis Ausgabe Grosstiere Nutztiere","volume":"52 1","pages":"33-41"},"PeriodicalIF":0.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139983835","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}

{"title":"[Selective dry cow therapy on dairy farms in Rhineland-Palatinate, Saarland and Hesse, Germany - a survey among farmers].","authors":"Theresa Scheu, Friederike Reinecke, Lisa Münnich, Amely Campe","doi":"10.1055/a-2219-9154","DOIUrl":"10.1055/a-2219-9154","url":null,"abstract":"<p><strong>Objective: </strong>With the Regulation (EC) 6/2019, antibiotic drying off of the entire dairy herd is no longer permissible. Hence, it is necessary to establish selective antibiotic drying off (SDCT: Selective Dry Cow Therapy) in dairy herds. With the publication of the PraeRi study in 2020, systematic data for the implementation of SDCT on farms became available for several German states. For Rhineland-Palatinate, Saarland and Hesse this type of information is only available from individual projects. Therefore, the aim of this survey was to increase the knowledge concerning the implementation of SDCT in dairy farms located in these states.</p><p><strong>Material and methods: </strong>An online questionnaire was sent via newsletters to farmers and was published in the regional farmers' bulletins in the described catchment area. The questionnaire inquired about the saving of antibiotics during drying off, the criteria guiding the farmer's decision (cell count from monthly dairy herd improvement data (DHI), mastitis history, microbiological examination of quarter foremilk samples, California mastitis test), use of teat sealants and the type of dry off procedure (abrupt/gradual).</p><p><strong>Results: </strong>A total of 103 questionnaires were evaluated, making the response rate ~1% for Hesse, ~3% for Saarland, and ~5% for Rhineland-Palatinate based on the number of included farms. Approximately 29% of the farmers dried off one out of four cows, 20% half, 23% three out of four and 13% all cows without using antibiotics. Eighty-nine farm managers based their decision on the somatic cell counts of DHI. Additional criteria influencing the decision were the mastitis history, results of the California Mastitis Test, or a combination of both. In 76 farms cows were dried off abruptly. In 79 farms teat sealers were used.</p><p><strong>Conclusions: </strong>Application of SDCT is established in most of the farms that participated in the survey, even though the proportion varied between farms. Legal requirements are not the only reason farmers need to increasingly deal with SDCT; sustainability programs of the dairies rely on selective drying off as well. Herd veterinarians should be supportive in implementing these measures to achieve good udder health while reducing the use of antimicrobials to a necessary minimum.</p>","PeriodicalId":23115,"journal":{"name":"Tieraerztliche Praxis Ausgabe Grosstiere Nutztiere","volume":"52 1","pages":"5-15"},"PeriodicalIF":0.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139983888","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}

The present study provides an overview of the distribution of <i>Mycobacterium avium</i> ssp. <i>paratuberculosis</i> (MAP) in 165 Thuringian sheep and goat flocks.

A positive association was identified between the detection of MAP or MAP-specific antibodies in a flock and flock size, as well as positive association between the measured value in the Elisa (s/p ratio) and the age of the animal.
