Abstract
Prevalence and intensities of hepatic parasites in bovine (Bostaurus) and caprine (Capra hircus)animal hosts at slaughter were evaluated at the Sabo-Tasha and Kakuri abattoirs within Kaduna, Nigeria. Intact gall bladders of randomly selected slaughtered animals of known sexes and ages belonging to both species were obtained from butchers at the abattoirs. Bile samples from the gall bladders were subjected to the centrifugal sedimentation technique of eggs isolation. Eggs of encountered parasites were examined microscopically, counted and identified by the aid of pictorial keys. Of the total of 250 caprine host species,28(11.20%) were positive with the eggs of Fasciola gigantica while 127/250 (50.80%) of bovine host species had the parasites. Eggs of other parasites observed in the animals were those of Dicrocoelium dendriticum in 33/250(13.20%) of caprine and 80/250 (32.00%)of bovine hosts. Single parasite infections occurred in 56(22.40%) and 99(39.60%) caprine and bovine hosts respectively; while mixed parasite infections occurred in 8(3.20%) and 111(44.40%) caprine and bovine hosts respectively. Age-specific intensities of caprine Fasciola and Dicrocoeliuminfections were statistically significantly different (P>0.05). Age-specific intensities of bovine Fasciola infection were also statistically significantly different (P<0.05; 7-9years >4-6years > 1-3 years). The respective mean values for cattle aged <1-3, <4-6 and 7-9 years being ±62.26, ±296.31 and ±965.25. Intensities of bovine Dicrocoelium infection were statistically significantly higher (P<0.05) in animals aged 7-9 years than in the lower age groups. Intensities of Fasciola and Dicrocoelium eggs in bovine hosts were significantly higher (P<0.05) in animals slaughtered and examined at the Sabo-Tasha than Kakuri abattoir. The study concluded that caprine and bovine hepatic parasite infections were high in the study location and recommends intensification of control measures to stem the tide.
