Efficacy of myrrh in controlling coccidioses in chickens.

Abstract

Myrrh was used for controlling the infection with Eimeria species in chickens. A total of 120 one-day-old native breed chickens bought from commercial hatchery were used in the experiment. Birds were feed on starter balanced ration free from anticoccidial drugs. At age of 2 weeks the chickens were divided into 4 groups (1-4), 30 chicks each. Chickens of first group were inoculated by 50,000 sporulated oocysts of mixed local field isolated Eimneria species and served as infected non treated control group. Birds of the second group were infected similarly and received simultaneously 10 mg Myrrh / bird by oral route. Birds of group 3 was supplied with Myrrh 10 mg / bird one day before infection by coccidia (50000 oocyst/bird). Last chicken group was left as non infected non treated control group. Measurements to evaluate the efficacy of Myrrh as anticoccidial drug included; mortality percentage; lesion score at 5 day post infection and the total oocyst output/gm of fecal dropping. The results showed that the mortality rate reached 10% and 3.33% in groups 2&3 respectively, while it reached 26.66% in infected non treated control group. High lesion score was recorded in infected non treated group followed by infected treated chicken groups regardless the time of treatment. The feed conversion rates reached 3.14 in infected non treated chicken group against 2.47 & 2.21 in treated chickens groups, 2&3 respectively. Mean oocyst count per gram faecal dropping (OPG) was reduced significantly in group 3 when compared with other infected treated or infected non treated chicken groups.
