Abstract:
ABSTRACT
Cross-sectional study was conducted from November 2014 up to March 2015 to determine the
Prevalence and to assess the risk factors of calf coccidiosis in and around Deberebrhan town. Faecal
samples were collected from a total of 384 calves with less than 24 months of age and examined for
the oocysts of coccidia. Detailed information of the age, sex, breed, management system, hygienic
status and faecal consistency were taken in consideration. Centrifugal faecal floatation technique using
salt solution was used to detect coccidian oocyst. The current study has revealed that Out of all 384
samples a total of 104 samples (27.1%) were positive for coccidiosis. Coccidian oocysts were detected
in calves from birth up to 2 years of age but greater prevalence was observed in age categories less
than 6 months of age. Statistically significant association (p<0.05) between prevalence of coccidiosis
and age, breed faecal consistency, hygienic status and management system was observed in this study.
With regard to sex, the prevalence in female calves (29.3%) was a bit higher than males (23.9%).
However, the difference was not statistically significant (P>0.05) between the sexes. Sex of calves was
not found as risk factor influnceing the preavalence of coccidiosis.This study shows that coccidiosis
was prevalent in and around Deberebrhan which signifies coccidian infection has a great significance
for the livestock producer. So, it needs awareness creation, a serious treatment, control and preventive
programs.
