ABSTRACT:
Pyridine derivatives having the formula ##STR1## wherein R.sub.1 is an alkyl group having 1 to 3 carbon atoms; R.sub.2 is hydrogen atom or an alkyl group having 1 to 3 carbon atoms; R.sub.3 is hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkenyl group having 3 or 4 carbon atoms, an alkyl group having 1 or 2 carbon atoms and hydroxy as a substituent, an alkanoyl group having 1 to 18 carbon atoms, an alkenoyl group having 3 to 11 carbon atoms, an aromatic acyl group having 6 or 10 carbon atoms in the aromatic ring and optionally alkyl, alkoxy, acetylamino, cyano or halogen as a substituent, a heterocyclic acyl group, an alkylcarbamoyl group having 1 to 4 carbon atoms in the alkyl moiety, an allylcarbamoyl group or hydroxy group; n is an integer of 0 to 2 inclusive; and, when n is 2, R.sub.1 's may be the same or different; provided that when R.sub.2 is said alkyl group having 1 to 3 carbon atoms, R.sub.3 is said alkyl group having 1 to 4 carbon atoms.
They are highly effective in the treatment of coccidiosis.
