Treatment of induced enterotoxigenic colibacillosis (scours) in calves by the lactoperoxidase system and lactoferrin.

The clinical efficacy of a preparation based on the lactoperoxidase system (LP-s) and lactoferrin (LF) was tested in calves experimentally infected with E coli K99+, Ent+. Mortality, occurrence and duration of diarrhoea were significantly lower (P less than 0.05) and general clinical status significantly better (P less than 0.05) in infected calves treated with LP-s and LF preparation than in infected but non-treated calves. Results suggest that LP-s and lactoferrin are effective in the treatment of enteric colibacillosis in calves.
