Abstract

A retrospective study on the prevalence of Bovine Cutaneous Eosinophilic Granuloma referred
to as “Shika Ulcer” in a livestock research farm is reported.A total of 50 cases (6.4%) out of 783
(93.6%) bovine cutaneous conditions were diagnosed at the Animal Health Unit of the Institute
during a ten year period. Of the 50 clinical cases seen, 52.0% were in Bunaji (White Fulani),
22.0% in the Friesian – Bunaji crosses, 16.0% in Bokoloji, and 10.0% in N’dama breed.BCEG
showed remarkable seasonality in prevalence with over 80% of cases occurring during the rainy
season. Shika ulcer also showed sex bias in prevalence with 86.0% of the cases occurring in the
cows and 14.0% in the bulls. The reverse was however the case for age predisposition with
86.0% occurring in the adults and 14.0 in yearlings.The mean infected-Breed value is
23.66±1.93 (P<0.05), mean infected-sex 24.360±2.06 (P>0.05), infected-Age 24.32±2.08
(P<0.05) and Infected-Month 18.9±2.08 (P>0.05). According to this study, the important
significant factor in the prevalence of this condition is Breed and Age as the P value is less than
0.05. Significant statistical difference was observed in the age and breed predisposition (P
<0.05) for this condition in the study area.
