An experiment was conducted to investigate the effect of zinc (Zn) supplementation and different concentrations of calcium (Ca) and phosphorus (P) in wheat-based diets on the performance, immune responses and bone parameters of broiler chickens. A randomized complete block design with factorial arrangement was used (three concentrations of Zn supplementation×two concentrations of dietary Ca-P),...

this research was conducted to evaluate the effect of different zinc (zn) sources on performance, bloodmineral and cell counts of zandi lambs. 18 male lambs at weaning were supplemented with two differentsources of zinc, 25 ppm znso4 and 25 ppm zinc-peptide added to the basal diet as control. live bodyweight, weight gain and feed efficiency improved with zn-peptide supplementation (p

Indium (In) is commonly hosted in Sn-rich deposits but rarely reported in Sn-poor deposits. However, an In-rich and Sn-poor skarn deposit, the Qibaoshan Cu-Zn-Pb deposit, has been identified in south China. Geochemical analyses were undertaken on 23 samples representing the following mineral assemblages: sphalerite-pyrite, pyrite-chalcopyrite, pyrite-sphalerite-galena-chalcopyrite, pyrite, magn...

The Lagos lagoon is a depository of last resort for over 70% of the surface runoffs, drainage channels and important rivers flowing from interior Nigeria to the Atlantic Ocean. The surrounding densely populated and industrialized areas often result in the introduction of potential harmful materials into the Lagoon. This work is aimed at providing reference data for the quality assessment of the...

Rhizomes of Canna indica Linn. has its own great important medicinal value, so thenutritive value of the rhizome is determined. Rhizome of Canna indicais found rich in carbohydrate and have enough crude fiber (67.99 and 12.50% respectively) ; nutritive value being 319.15 Cal /100 g.Rhizome is rich in Potassium (24405 ppm) and sufficient in sodium, calcium and magnesium (7500, 1345 and 1610 ppmr...

Three experiments were conducted using feedlot steers in a randomized block design to determine the effect of zinc methionine (ZnMet) and zinc oxide (Exp. 3) on feed intake (DMI), rectal temperature, and serum mineral concentrations of feedlot cattle challenged with infectious bovine rhinotracheitis virus (IBRV). All the steers used were seronegative to IBRV. Steers were adapted for 7 d to thei...

Abstract Gallium (Ga) and germanium (Ge) are technologically important critical elements. Lead blast furnace slags from Tsumeb, Namibia, comprise over two million metric tons of material that contains high levels Ga (135–156 ppm) Ge (128–441 in addition to significant Zn concentrations (up 11 wt.%) represent a potential resource for these A combination mineralogical chemical methods (PXRD, FEG-...
