ABSTRACT
]]> The objectives of this study were to compare the efficacy of 6 different dry-cow intra-mammary antimicrobial products for the treatment and prevention of mastitis during the dry period in a well-managed high producing Friesland dairy herd, and the influence of treatment on the somatic cell count (SCC) of cows during early lactation.Key words: comparative study, cure rates, dairy cow therapy, new intramammary infections, product efficacy
