RELATIVE EFFICACY OF 4 ANTI-COCCIDIAL DRUGS AGAINST CECAL COCCIDIOSISINFECTION IN BROILER CHICKS

Relative efficacy of amprolium hydrochloride, nitrofurazone with furaz olidone, p-tolune sulphonyl-beta-methoxy-urethane and sulphadimidine a gainst experimental caecal coccidiosis was studied in broiler chicks. The post-infection mortality due to coccidiosis was higher in nitrofur azone with furazolidone and p-tolune sulphonyl-beta-methoxy-urethane m edicated groups than in other infected groups. The anticoccidial index and performance index were superior with amprolium hydrochloride medi cation, followed by sulphadimidine treatment. Immunity induced in all the therapeutic groups was comparable with infected unmedicated group.
