Epidemiological study on Haemoncus contortus, in small ruminants slaughtered at Jimma Town Municipal Abattoir, Oromia Region, Ethiopia

Abstract

Haemonchosis caused by Haemonchus contortus is a predominant, highly pathogenic, and economically important disease of sheep and goats. Cross sectional study using random sampling from November 2015 to march 2016 in a total of 384 sheep was conducted with objectives of determining the prevalence and associated risk factors of Haemonchosis in sheep slaughtered at Jimma town municipal abattoir in southwest part of Ethiopia in Oromia Regional State. The overall prevalence of Haemonchus contortus was 264 (68.75%). There was insignificant variation (P>0.05) in the prevalence of poor body condition 94 (85.5%), medium body condition 81 (66.9%) and in good body condition 89 (58.2%). The prevalence in adult sheep was 195 (69.6%) varies significantly (P<0.05) from that of young sheep 69 (67%), respectively. The prevalence of 85 (73.3%) in sheep that originated from Seka district compared to Dedo district 62 (68.9%), Mana district 40 (67.8%), Gomma district 25 (67.6%) and Kersa district 52 (63.4%) showed no significant variation (P>0.05). The mean Packed Cell Volume (PCV) of parasitaemic sheep was 23.73±3.7 and the mean Packed Cell Volume (PCV) of aparasitamic sheep was 37.66±4.736 statistically with significantly variation (P<0.05). The highest monthly mean worm burden was found in November (443.9) and lowest monthly mean worm burden was revealed on March (200). Statistical analysis showed there was significance (P<0.05) difference in monthly mean burden. It is concluded that the present finding revealed that significant numbers of sheep were in a high infection rate with Haemonchus contortus was observed. Hence strategic deworming and appropriate control measure with good husbandry practice should be implemented.
