Abstract
Cross-sectional study was conducted in Jijiga and Shinille Zones of Somali Regional State from
October 2008 to April 2009 to determine seroprevalence and associated risk factors. A multistage
sampling was used in pastoral and agropastoralsystem. A total of (n=616) goats, (n=202) sheep,
(n=110) cattle and (n=94) camel sera were collected for serological study. questionary survey
was conducted in pastoral and agro-pastoral system. The seroprevalence of PPR in goats and
sheep was 25.6% and 14.4% in the study area respectively. The seroprevalence was lower in
camels and cattle, which was 8.5% and 6.63% respectively. Goats were found to be more
susceptible than sheep, which was found to be statistically significant (p=O.OOO). However no
significant difference was observed between cattle and camel (P=0.558). Seroprevalence of goats
between Shinille Zone (pastoral) and Jijiga Zone (agro-pastoral) production system showed
44.09% and 18.9% in goats, 30.01% and 5.42 in sheep respectively. Sero prevalence increased
from 21.7%% to 28.9%%% in goats and from 8.1 %to 20.4%in sheep from young to adults age
respectively. There was significant difference between age groups in seroprevalence of both goats
(p=0.04) and of sheep (0.013). In case of cattle (p=0.062) and camel (p=0.249) statistically no
significance difference was observed between age groups in seroprevalence. Regarding sex,
26.4%, and 25.5% was found in goats (p=0.851), 15.6% and 14% in sheep's 8% and 5 %( p=O.
795) in cattle (p=0.488) and8.2% and 9.5% in camel (p=0.095) in male and female respectively.
There was statistically no significant difference between sexes in all species. According to the
respondent the number of goats affected by CCPP (Sunbub) and PPR (Kollere) was 32.8%,
21.4% and 25.7%, 14.3% in Shinille and Jijiga Zone respectively. However more goats are
affected by GIT parasite in Jijiga (40%) than Shinille zone (21.4%). Regarding susceptibility by
age 64.28% and 60.7% of the respondent replied that young goats and sheep were more
susceptible than adult animals. However, no response (0%) was made indicating susceptibility of
goats and sheep less than 6 months of age.
