The objective of this field study was to compare the udder health status as well as the clinical mastitis rate during the first 100 d of lactation in cows that received long-acting dry cow antibiotic alone (group AB) or in combination with an internal teat sealant (group AB + OS). The study was conducted during a 9-month period and included 136 Holstein cows from 12 dairy farms in Hessia, Germa...

Refining the recommended approach to mastitis control in dairy herds is a continual process. Recently developed concepts and practices are described. INTRODUCTION Even though great technological advances have been made, mastitis continues a major economic issue for dairy producers. Thus, researchers and dairy advisors continue to refine the National Mastitis Council (NMC) recommended mastitis c...

The value of electric conductivity (EC), California Milk Cell Test (CMCT) and somatic cell count (SCC) as diagnostic tools was investigated in dairy goats. Conductivity colour reading correlated with SCC. Milk samples with conductivity colour red had significantly higher SCC than those with conductivity colours green and orange (P < 0.001). There were moderate positive correlations between CMCT...
