Spectramast LC is used to treat clinical mastitis in lactating dairy cattle. Specifically, it's effective against mastitis associated with coagulase-negative staphylococci, Streptococcus dysgalactiae, and Escherichia coli (E. coli).
In simpler terms, Spectramast LC is an antibiotic medication administered to dairy cows that are currently producing milk to fight off bacterial infections (mastitis) in their udders. This infection can cause inflammation, pain, and reduced milk production. The drug targets certain bacteria known to cause this condition.
