Infectious bovine keratoconjunctivitis 2019
and animal welfare (Angelos, 2018). Powders and dyes are not recommended to cure IBK
because of the crystal structure, what cause irritation and lacrimation. As well oral drugs are
not eligible if infected animals are not separated. Most often are used subconjunctival,
intramuscular, intravenous and subcutaneous antibiotics (Brown et al., 1998). Studies show
that most effective and best for healing time are antibiotics such as penicillin, florfenicol and
cloxacillin indicate active treatment reduces healing time compared with placebo. Two
cloxacillin dosages of 20 mg/kg should be administered via intramuscular or subcutaneous 72
hours apart. Florfenicol, given once subcutaneously (40 mg/kg) or twice 2 days apart
intramuscularly (20 mg/kg) to experimentally infected calves. On the figure 2 are shown the
recovery processes, when the florfenicol is used to heal the pink eye (Angelos, 2015).
