Abstract:
A cross sectional study was conducted from February to May 2017
to investigate the prevalence of abomasal nematodes infection and to
assess the relationship between the occurrence of these parasites and
factors of age, sex, locality, body condition and breed in slaughtered
sheep in Khartoum State, Sudan.
A total of 350 abomasi were collected from three slaughterhouses
namely: Karary, Nasr eldeen and Sabaloga in Karary, East Nile and
Umbada localities respectively, and examined using postmortem
examination (worm recovery).
The result showed that abomasal nematodes infection is common in
sheep and the prevalence is estimated to be 15.1% (35/533). Worm
recovery revealed the presence of Haemonchus spp. in all positive
infested sheep with abomasal nematodes 100% (53/33).
The subsequent risk factors revealed association with sheep
abomasal nematodes in the univariate analysis under significant level of
P-value ≤ 0.5: sex (p-value = 0.000) and breed (P-value = 0.001). These
factors may be contributing factors for the relatively high prevalence of
abomasal nematodes among sheep.
