    摘要: A veterinary composition for the treatment or prophylaxis of infectious diseases caused by infectious microorganisms which comprises at least one pyridone-carboxylic acid compound of the formula:
    wherein
    R¹ is lower alkyl, halo(lower)alkyl, cyclo(lower) alkyl or substituted or unsustituted phenyl;
    R² and R³ are each hydrogen, hydroxyl, lower alkoxy, halogen or a group of the formula: -CH₂N(R⁵)R⁶ (in which R⁵ and R⁶ are each hydrogen, lower alkyl, lower alkenyl or hydroxy(lower)alkyl);
    R⁴ is hydrogen, oxo, hydroxyl, lower alkoxy, halogen or a group of the formula: -CH₂N(R⁷)R⁸ (in which R⁷ and R⁸ are each hydrogen or lower alkyl;
    X is hydrogen or halogen;
    Y is CQ (in which Q is hydrogen or halogen) or nitrogen or, when taken together with R¹, may form a group of the formula: =C-OCH₂C(R⁹)H- (in which R⁹ is hydrogen or lower alkyl and the carbon atom to which R⁹ is attached links to the nitrogen atom in the pyridone ring); the compound themselves and a process for their production.
