    The study was conducted to determine the effects of Hibiscus calyx extracts on the blood chemistry of broiler chickens. One hundred and twenty birds were used for the study. The birds were randomly assigned into 2 equal groups (n=60). Animals in group 1 serve as control and were given clean drinking water, birds in group 2 were administered Hibiscus calyx extracts in drinking water. The experiment lasted for 30 days. Mean values for Hemoglobin, packed cell volume, red blood cell and white blood cells were similar for both groups. There was no significant difference in the mean values of urea, total protein, albumin, Alkaline phosphatase, SGOT, SGPT and globulin (P>0.05). However, significant difference in the mean values of cholesterol was recorded (P<0.05). Findings of this research indicate that administration of Hibiscus calyx extracts result in lower blood cholesterol levels

    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
