Abstract
A detailed study on the prevalence, clinical pathology and treatment of coccidial infections in cattle belonging to all age groups was undertaken at the Veterinary Hospitals, University Livestock Farm,
Buffalo Breeding Station, Cattle Farm, Pattambi, Kerala Agricultural University and other localities in Thrissur during the period from June 1999 to May 2000.
The prevalence of the infection was found to be 2.2 per
cent. On the whole, the incidence of coccidiosis was
found to be high in animals below one year, and female
animals, during the rainy and humid months. Clinical
signs; predominantly blood tinged or foul smelling
diarrhoea and the microscopical examination of the
faecal samples from suspected cases were made use of
for diagnosis. Eight Eimerian species causing coccidial infections in cattle were identified and they were
Eimeria bovis (35 per cent), E. zuernii (55 per cent),
E. subspherica (10 per cent), E. ellipsoidalis(60 per
cent), E. cylindri ca (fi ve per cent), E. bareillyi
(five per cent), E. brasiliensis (five per cent) and
E. wyomingensis (10 per cent). The most commonly encountered species were E. ellipsoidalis, E. bovi s,
and E. zuernii. Haematological studies of clinically infected animalsrevealed reductio in the values of
haemoglobin, packed cell volume, total leukocyte and
lymphocyte counts. A reduction in serum total protein
and globulin fractions was also observed during the
assay of serum protein fractions in these animals.
Treatment trials against bovine coccidiosis using
drugs, Sulphadimidine sodium (125 mg per kg body weight
for three days), Amprolium hydrochloride (20 mg per kg
body weight for five days) and Salinomycin (2 mg per kg
body weight for 21 days) orally resulted in nearly cent
per cent efficacy in the clinically affected animals.
All the three drugs were found to be equally effective.
