Prevalence and Risk Factors of Sheep Haemonchosis in Khartoum State, Sudan

Abstract

A cross sectional study was conducted from March to May 2015 for determination of ovine haemonchosis and investigation of associated potential Risk Factors in Khartoum State, Sudan. A total of 170 fecal samples from Sheep were collected and examined using Direct smear and Centrifugal flotation test and then culture of faeces. The result indicated that natural Haemonchus contortus infection was prevalent among sudanese sheep at Khartoum State with an overall prevalence 6.5%. The following risk factors showed association with sheep haemonchosis in the univariate analysis under significant level of P-value ≤ 0.25: bread (P-value= 0.023), housing type (P-value =0.026), source of water (P-value= 0.065), use of anthelmintics (p-value=0.002), owner knowledge (p-value=0.003), vegetation area (p-value=0.073), type of soil (P-value= 0.000) and localities (P-value= 0.032). Using multivariate analysis to determine possible significant association between haemonchosis and potential risk factors, the result showed that there was no significant association with any of the investigated risk factors. The highest prevalence of infection was in karary (18.2%), and East Nile (17.6%), then Bahri (12.5%), and Omdurman (2.7%). Whereas the lowest prevalence of infection was in Khartoum (0%) and Jabal al Awliya (0%) and um bada (0%).
