Prevalence, Clinico- Pathology And Control Of Coccidiosis In Broiler Chicken - Mannuthy Department of Parasitology, College of Veterinary and Animal Sciences 1997
An investigation was carried out with an objective to
findout the prevalence, clinicopathology and control of
coccidiosis in broiler chicken. The prevalence of coccidiosis
in broiler chicken by viscera examination was 21.13% and by
the examination of faecal sample from different broiler farms
was 10.65%. The highest prevalence of coccidiosis was during
the warm wet climate (September to November). There was
prevalence of three species of Eimeria namely E. tenella
(72%), E. necatrix (36%) and E. maxima (1.33%) and mixed
infection with E. tenella and E. necatrix in 9.33% cases.
Haematological studies revealed increase in erythrocyte
sedimentation rate and total leucocyte count than the control
and a decrease in the values for PCV, Hb content and total red
blood cell count.
Histopathological observations revealed proliferation of
goblet cells, moderate mononuclear cell infiltration,
degeneration and desquamation of caecal mucous membrane and
haemorrhage at different depths of the intestinal wall caused
by the rupture of the large second generation schizonts.
Among the three anticoccidials evaluated salinomycin was
the best drug based on the mean weekly body weight, mean
weekly body weight gain and performance index followed by
monensin. Performance of salinomycin treated birds were
comparable with that of noninfected-nonmedicated control in
the above parameters. Amprolium hydrochloride was least
efficient.
