The invention provides new hexahydro-1,2,4-triazine-3,5-dione derivatives having anticoccidiastatic activity. The new derivatives are those of the general formula I:
in which R3 represents a hydrogen atom; an alkyl, tetrahydrofuryl or alkylsulphonyl radical; a radical
in which R4 represents an alkyl radical which is optionally substituted by a halogen atom, or by an alkoxy carbonyl or alkoxy radical; a phenyl radical substituted by one or more halogen atoms, nitro groups or lower alkyl groups; a benzyl radical substituted by one or more halogen atoms; a phenylthiomethylene or phenylaminomethylene radical substituted by one or more halogen atoms; a thienyl radical optionally substituted by one or more halogen atoms; or a CO-hexahydro-1,2,4-triazine-3,5-dione; R5 and R6 are the same or different and each represents a hydrogen atom or an alkyl group, or R6 also represents an alkali metal or alkaline earth metal atom; and A represents a group of the general formula:
in which X represents one or more halogen atoms; or a group of the general formula:
in which R1 and R2 are the same or different and each represents a hydrogen or halogen atom or a trifluoromethyl, alkyl, cyano or alkoxy radical; with the proviso that one ofthe substituents R1, R2, R3, R5 and R6 must be other than hydrogen.
The derivatives of the invention are useful as part of a feed or a feed pre-mix or for addition to drinking water.
