Orbenin Extra Dry Cow is recommended for routine use in cows at drying off, to treat existing intramammary infections and to provide prolonged protection against new infections during the dry period. The concomitant use of Orbeseal™ at drying off provides additional protection against the ingress of udder pathogens, contributing to preventing both subclinical infections and clinical mastitis during early lactation.
Orbenin is active against Gram-positive organisms associated with mastitis. These include: Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, penicillin-resistant and sensitive staphylococci, and Actinomyces pyogenes. Orbenin is bactericidal in action and is not destroyed by staphylococcal beta-lactamase. It is, therefore, active against penicillin-resistant staphylococci which are an important cause of mastitis.
