RISK FACTORS ASSOCIATED WITH BOTH BLOOD AND INTERNAL PARASITES IN DAIRY FARMS IN KUKU AREA, KHARTOUM STATE

Abstract

Investigation of blood and internal parasites among different seasons
(dry cool, dry hot and wet hot) in dairy herds in Kuku area of Khartoum
State, revealed that there was a high prevalence of blood parasites in the
dry cool season (46%) compared to dry hot and wet hot season (14.74%
and 5.68%, respectively). While the presence of internal parasite was
found to be less than infection with blood parasites (15%, 8.42% and
11.36 for dry cool, dry hot and wet hot season, respectively). A positive
association (χ
2
=48.483, P<0.01) was found between season and presence
of blood parasites and season is considered to be a protective factor (OR=
0.244). In contrast, presence of internal parasites was not associated with
season (χ
2 = 2.058, P>0.05). Tick infestation was found statistically
significant (χ
2 = 20.583, P<0.01) with respect to presence of blood
parasites and could be a risk factor (OR=3.586). Packed cell volume
(PCV) was found strongly associated with both blood and internal
parasites (χ
2
= 9.679 &6.573 P<0.01, respectively
