Claims3
A method of treating coccidiosis in a fowl in need of such treatment which comprises administering to the fowl both a first substance and a second substance, said first substance being a polyether antibiotic and said second substance selected from compounds of the formula ##STR3## wherein R.sup.1 represents bromo or chloro,
- m represents an integer of 0 or 1 and n represents an integer of from 0 to 3, with the sum of m and n being an integer of from 1 to 3;
- R.sup.5 represents difluoromethyl, chlorodifluoromethyl, 1,1,2,2-tetrafluoroethyl, or a perfluoroalkyl of C.sub.1 -C.sub.3 ;
- and
- R.sup.6 represent sodium, potassium, lithium, silver, calcium, ammonium, or substituted ammonium derived from an organic amine which is as basic as, or more basic than, ammonia;
- said first and second substance being administered in amount which together, are effective to treat coccidiosis in the fowl.
An animal feed premix comprising from 0.2 to 25.0%, by weight, of a first substance, and from 0.2 to 25.0%, by weight, of a second substance,
- (1) said first substance being a polyether antibiotic, and
- (2) said second substance being selected from the compounds of the formula ##STR4## wherein R.sup.1 represents bromo or chloro,
- m represents an integer of 0 or 1 and n represents an integer of from 0 to 3, with the sum of m and n being an integer of from 1 to 3;
- R.sup.5 represents difluoromethyl, chlorodifluoromethyl, 1,1,2,2-tetrafluoroethyl, or a perfluoroalkyl of C.sub.1 -C.sub.3 ;
- and
- R.sup.6 represents sodium, potassium, lithium, silver, calcium, ammonium, or substituted ammonium derived from an organic amine which is as basic as, or more basic than, ammonia.
