Abstract Purpose Staphylococcus aureus ( S. ) is the most important pathogen involved in bovine mastitis dairy production. produces a spectrum of extracellular protein toxins and virulence factors which are thought to contribute pathogenicity organism. The aim this work was isolate molecular characterize associated with subclinical central part Ethiopia. Methods A total 265 lactating cows from ...

The relationship between initial Somatic Cell Count (SCC) and time to first clinical mastitis was estimated from data including 20,422 Holstein heifers, without clinical signs of mastitis during the first month of lactation and with a first test day SCC lower than 400,000 cells /ml. Number of days from 35 days after first calving to first clinical mastitis event in first or second lactation was...

The aim of the paper was to estimate the accuracy of the metrology of an installed indirect on-line sensor system based on the automated California Mastitis Test (CMT) with focus on the prior established device-dependent variation. A sensor calibration was implemented. Therefore, seven sensors were tested with similar trials on the dairy research farm Karkendamm (Germany) on two days in July 20...

Despite more than 30 years of research into mastitis diagnostics, there are few alternatives to the somatic cell count (SCC) in practical use for identification of cows with subclinical mastitis. Mastitis is not only an animal welfare problem, but also affects the yield, composition and technological properties of milk. Hence, dairy cooperatives give farmers a premium quality payment to encoura...

AIM The present study was designed to evaluate the neutrophil dynamics in terms of the functional competence during subclinical mastitis (SCM) and clinical mastitis (CM). MATERIALS AND METHODS A total of 146 Karan fries cows were screened and were divided into three groups as control (n=12), SCM, n=12 and CM, n=12 groups on the basis of California mastitis test scoring, bacteriological evalua...

The objective of this research was to investigate the potential of mid-infrared (MIR) analysis of milk to provide indicators of the udder health status of dairy cows. Mastitis data collected in 49 Walloon herds were merged with test-day data including milk composition and MIR spectra. A total of 1987 healthy lactation and 3204 lactations with at least one mastitis, clinical or sub-clinical, chr...
