    Preliminary Screening of Some Nutraceuticals as Aflatoxin (Aspergillus flavus) Reduction Agents Using In Vitro growth Inhibition Technique
    (Department of Animal Science, Nasarawa State University, Keffi., 2020-09-30) Ari, Maikano Mohammed; Hassan, D.I; Yakubu, Abdulmojeeb; Adua, M. M
    The following nutraceuticals: Moringa oleifera Lam., Garlic (Allium sativum) and Ginger (Zinger officinale) were screened for their possible use as Aflatoxin (Aspergillus flavus) reduction agents by extracting their photochemical constituent’s using aqueous and methanol extraction which were used as inhibitors of A. flavus . The results showed the presence of tannins, steroides, cardiac glycosides, anthraquinone, flavonoids, alkaloids terpenes and saponins in all the tested nutraceuticals. Methanol extraction had highest concentration of the phytochemical constituents in each and the growth inhibition zone of A. Flavus showed that the extracts of Moringa oleifera leaves, Garlic (Allium sativum L) and Ginger (Zingiber officinale) inhibit the growth of A. flavus in methanol extract, while aqueous extraction showed no zone of inhibition. The sensitivity results obtained revealed significant (p>0.05) difference on zones of inhibition at different concentrations of 12.5, 25, 50, 100 and 200mg/ml of the extracts of Moringa oleifera leaves (A), Garlic (B) and Ginger (C) and for methanol extracts (A), (B) and (C) at concentration of 12.5mg/ml. The highest zones of inhibition is extract (C) at 200mg/ml. The constituents in these nutraceuticals and the sensitivity results obtained indicates that these nutraceuticaals could be used as phytogenic feed additive for the inhibition of growth of mycotoxins in feeds

    PREVALENCE OF HEAMOPARASITES (BABESIA SPECIES) IN SHEEP UNDER THE TRADITIONAL SYSTEM OF MANAGEMENT IN LAFIA METROPOLIS NASARAWA STATE, NIGERIA
    (Department Of Science And Laboratory Technology, Nasarawa State University Keffi., 2016-04-09) Adua, M. M; Idahor, K. O; Panda, A. I.; Omeje, J. N
    A study of the prevalence of Babesiosis in fifty sheep was conducted in Lafia metropolis within four (4) wards of Lafia, LGA (Shabu/Kwandere, Makama, Gayam and Chiroma wards, respectively) from February to May, 2013., to reveal the prevalence of Babesiosis in Sheep. The fifty sheep sampled were across different breeds, sexes and ages, amongst which were Yankasa, West African Dwarf and Balami. Two milllilitres of blood samples were collected from each sheep and analyzed using thin and thick smears - Giemsa stain. The stained slide preparations were microscopically viewed under x 40 objective. The results revealed that most Babesia species occur with varied prevalence. The study confirmed the prevalence of infections due to parasites (Babesia) and tick infestation in Lafia Metropolis. It also revealed that B. ovis were exerting more burden on the animals compared to B. motasi. The different breeds of sheep sampled showed that West African Dwarf sheep were more resistant to Babesia species. The percentages of infection rate of parasites were, 6.98% and 71.43% of B. motasi. The PCV mean values among the four (4) wards varied at 23.56, 21.4, 23.67 and 23.30, respectively.
