تحديد شدة و نسبة الاصابة المفردة و المختلطة بداء الاكريات ( Coccidiosis ) في مزارع دجاج اللحم في كل من محافظات اللاذقية و طرطوس و ادلب (سورية)

Based on the results of the study which lasted from1999 to 2003, it can be said that all poultry farms are infested with coccidiosis, which is intensely spread but in varying percentages, particularly in the coastal region. This is because it has the most suitable climate for this disease. Infestation percentage in the governorates of Tartous, Lattakia, and Idleb are (85.28%), (84.05%), and (83%), respectively. The average infestation percentage during the five years of study is (84.28%). It has also been noticed that infestation percentage increases with the 1 time of study, which calls for increasing austerity in implementing health conditions, studying the efficiency of previous prophylactic programs, testing the effectiveness of anti-coccidiosis drugs that are in use for a long time, and developing guaranteed substitutes. The results also demonstrated that the varying infection is common, where it reached (62.30%); whereas the rate of single infections reached (37.70 %). Severity of most cases ranged between mild (+) and moderate (++) in the governorates studied. Infestation rate with secal Eimeria tenella (%60,73) followed by E.maxima(%41,88),then E. acervulina (%26,8), then E.brunetti (%2,82).
