| In an organic dairy herd (250 cows) a homeopathic dry cow treatment should be evaluated while an antibiotic dry cow therapy (DCT) was totally abandoned. A ran-domized placebo-controlled double blind study with a herd specific nosode (D30) was conducted. Either 5 ml of the nosode (VG) or a placebo (KG) was orally administered in weekly intervals four times before drying off, at the day of calving and seven days post partum (p.p.). The efficacy of treatment was measured according to quarter foremilk samples at the days of treatment, six weeks p.p. and at the end of the 2nd and 3rd month of lactation. Data of 129 cows with 512 quarters (VG:n=65/260; KG:n=64/252) was evaluable. New intramammary infections (IMIn) cure rates and cases of clinical mastitis in... |

| Between 2012 and 2014, ABYS study recorded antibiotic use, detection and resistance data for 23 organic and 35 conventional pig farms. Antibiotic contents of farm-made fertilizers were assessed by LC/MS-MS. Phenotypic antimicrobial resistance was investigated in Escherichia (E.) coli (indicator bacteria); antimicrobial resistance genes of the total bacterial microbiota (sul(II), tet(A), tet(B), tet(M); marker Measured in nUDD (number of animals treated multiplied by treatment days), colistin was the most frequently used antibiotic, in organic farms followed by tylosin, doxycycline and amoxicillin. Antibiotic residues were rarely detected; however, manure contained up to 10^8 antimicrobial resistance genes per gram; concentrations were higher when the... |

| Die Trockenperiode sowie die peripartale Phase stellen im Produktionsablauf einer Milchkuh den Zeitraum des größten Mastitisrisikos dar. Nach wie vor ist die antibiotische Behandlung zum Laktationsende das Standardverfahren zur Therapie und Prophylaxe von Infektionen in der Trockenphase. Dies wird aber zunehmend kritisch betrachtet, insbesondere wenn es sich zum Zeitpunkt des Trockenstellens um eutergesunde Tiere handelt. In einigen skandinavischen Ländern wird aufgrund gesetzlicher Rahmenbedingungen weitgehend auf den Einsatz von Antibiotika zum Trockenstellen verzichtet. Darüber hinaus werden die Gefahr der Resistenzbildung, sowie Rückstände oder Kontamination von Lebensmitteln diskutiert. Vor diesem Hintergrund gewinnen nicht-antibiotische Verfahren zum... |
