CL 259,971: a potent new polyether anticoccidial. 1. Battery efficacy and safety. 1984

S Kantor, and R H Schenkel

The anticoccidial activity of CL 259,971, a new polyether ionophore produced by Actinomadura yumaense sp. nov, has been demonstrated against six species of poultry Eimeria, tested individually or in mixed species infections. Statistically significant activity was obtained against some species with as little as 2.5 ppm of drug. The optimal treatment level, however, was determined to be 5 ppm. At this level, performance was comparable to 100 or 120 ppm of monensin. CL 259,971 is coccidiocidal and affects the early asexual stages of the life cycle of E. tenella. Fed to uninoculated cockerels in batteries at 10 ppm for 7 weeks, CL 259,971 permitted numerically superior weight gains when compared with 200 ppm of monensin.

D008985	Monensin	An antiprotozoal agent produced by Streptomyces cinnamonensis. It exerts its effect during the development of first-generation trophozoites into first-generation schizonts within the intestinal epithelial cells. It does not interfere with hosts' development of acquired immunity to the majority of coccidial species. Monensin is a sodium and proton selective ionophore and is widely used as such in biochemical studies.

D011201	Poultry Diseases	Diseases of birds which are raised as a source of meat or eggs for human consumption and are usually found in barnyards, hatcheries, etc. The concept is differentiated from BIRD DISEASES which is for diseases of birds not considered poultry and usually found in zoos, parks, and the wild.
