Occurrence of caecal coccidiosis in laying hens following various experiments

Abstract

Several experiments were conducted the same day using Lohmann brown laying hens from a farm located at the periphery of Ndjamena. A 6.6% mortality rate was recorded six days later. Post-mortem examinations, parasitological and microbiological analyses helped identify Eimeria tenella as the causal agent. In conclusion, the combined effects of these experiments have decreased the resistance of the birds and induced the onset of the disease.
