Abstract

Haemoparasites of small ruminants reduce their productivity and could lead to high mortality. Information on the prevalence of haemoparasites in Balami sheep reared by the Fulani pastoralist in Maiduguri, Sudan “ Sahel Savannah zone of Northeastern Nigeria need to be updated. Our study therefore aimed at investigating the prevalence of haemoparasites of Balami sheep and its effect on some haematological parameters. This study was carried out between the months of March and September 2015. Two hundred and fifty (250) blood samples were collected from apparently healthy sheep of various age groups of both sexes during the study period and examined for the presence of haemoparasites using standard parasitological techniques. An overall 18.40% prevalence rate of haemoparasitic infection was recorded in the sampled Balami sheep. Anaplasma (9.60%), Babesia (5.20%). Theileria (2.80%) and Trypanosoma (0.80%) species were the genera of haemoparasites encountered in the infected sheep.The haemoparasitic infection rate were found to be higher in adult (14.0%) sheep compared to the young (4.40%) ones. There was statistical significant difference (P-value= 0.0022) between haemoparasitic infection rate and age groups of infected sheep. Moreover, the haemoparasitic infections encountered was higher in females (10.80%) than in the male (7.60%) sheep. There was no statistical significant difference (P-value= 0.148) between haemoparasitic infection rate and sexes of infected sheep. Considering the relationship between body condition scores and haemoparasitic infection it was found that infection rate was statistical significantly (P-value= 0.045) higher in the poor (16.40%) than in the good (2.0%) body condition scored sheep. Packed cell volume (PCV) and haemoglobin concentration (Hb) of haemoparasites uninfected and infected Balami sheep examined revealed that, uninfected sheep had a significantly higher mean ± SD (range) of PCV and Hb of 28.84 ± 3.4 and 9.55 ± 1.1 against the infected sheep 21.42 ± 3.7 and 7.22 ± 1.2 respectively (P<0.05). The prevalence of haemoparasites recorded among Balami sheep in the study area may suggest a preponderance of their vectors. It was also observed that Balami sheep infected with distinct genera of haemoparasites have relatively low PCV and Hb concentration which indicate anaemia. This revealed the existence of possible economic significant effect of the haemoparasites in Balami sheep in the study area which call for increased routine screening to reduce the pathophysiological effect of the parasites and sustainable strategic measures should be taken to control the vectors involved in their transmission.
