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

Abstract

A cross sectional study was conducted from June 2013 to August 2013 for determination of ovine Haemonchosis and investigation of associated potential risk factors in Khartoum state, Sudan. A total of 240 fecal samples from Sheep were collected and examined by egg count and then culture of feces. The result indicated that natural Haemonchus contortus infection was prevalent among Sudanese sheep at Khartoum state with an overall prevalence 12.1%. The following risk factors showed association with sheep Haemonchosis in the univariate analysis under significant level of P-value ≤ 0.25: age (P-value= 0.000), breed (P-value =0.004), fecal consistency (P-value = 0.000), grazing type(P-value= 0.009), use of anthelmintics (p-value=0.000), other disease status (P-value 0.257), other XI animal Species (p-value= 0.109), season (P-value = 0.114), type of soil (P-value= 0.208) and rainfall status (P-value= 0.114). Multivariate analysis showed there was significant association between sheep Haemonchosis and the following risk factors: age (p-value=0.000), breed (p-value=0.004), fecal consistency (p-value= 0.000), grazing system (p-value= 0.009) and using of anthelmintics (p-value= 0.000).
