Forty-five Angus steers (avg initial wt 330 kg) were individually fed for 112 d to assess the value of supplemental Zn and source on performance and carcass quality. Steers had ad libitum access to a control diet (81 ppm Zn) of 33% whole corn, 33% ground milo, 15% cottonseed hulls and 13% cottonseed meal, or this control diet with 360 mg Zn/d added from either zinc methionine or zinc oxide. Ste...

The major goal of this study is to determine the bioaccumulation heavy metals in tissues and bones Red Hybrid Tilapia <i>(Oreochromis niloticus)</i> Mackerel <i>(Rastrelliger kanagurta)</i> taken from two distinct sites Terengganu state, Malaysia, namely Kijal Paka. Zinc (Zn), copper (Cu), nickel (Ni), lead (Pb)were examined. Soil analysis also was carried out for same e...

Our aim to establish the metal (Pb, Cd, Cr, Cu and Zn) levels of Mammalian scat samples deriving from sanctuaries of western Rajasthan and comaprision between the concentrations of Talchaper Blackbuck Sanctuary, Churu and Dhavadoli Protected Area, Jodhpur. Restric tions on the sampling because of Wildlife Protection Act (1972) prevents taking of samples of living tissues to analyse body burdens...

Adsorption of zinc (Zn), cadmium (Cd), and nickel (Ni) from aqueous solutions by corncob (CC) granular activated carbon prepared (GACC) were carried out. Synthetic Cd, Ni, Zn at 3.0 ppm each used to perform the adsorption process. A batch pattern was determine kinetics as well isotherm parameters. The obtained results using either both CC GACC separately found be matched with Langmuir model. Fu...

Covalent (E-P) and noncovalent (E X P) phosphoenzyme intermediates exist on the reaction path of alkaline phosphatase of Escherichia coli. Zn(II) and Cd(II) alkaline phosphatases both form E-P and E X P from inorganic phosphate. These intermediates show well separated 31P NMR resonances in slow chemical exchange with respect to each other and to unbound phosphate. The 31P signals of E X P of al...

AIM The main objectives of this study were for comparing the effect of batteries and deep litter rearing systems of domesticated Japanese quail, Coturnix coturnix japonica, on the concentration levels of cadmium, copper, lead, and zinc from the quail meat and offal in Ismailia, Egypt. MATERIALS AND METHODS A total of 40 quail meat and their offal samples were randomly collected from two main ...

The geochemical composition of surface soils and potential bedrocks in Davarzan area has been investigated to determine soil origin and evaluate environmental aspects. Davarzan plain is composed of soils and deposits derived by weathering and transportation of different bedrocks from northern mountains. The bedrocks consist of Eocene (andesitic to basaltic lavas and volcano-sedimentary rocks co...

Ehrlich ascites cells were cultured under different O2 partial pressures from less than 0.1 ppm to 2 x 10(5) ppm. During the artificial hypoxia and following reoxygenation the DNA synthesis rate was measured and the relative frequency of replicon initiations was examined by analyzing the length distributions of replicative daughter strand DNA. These studies were complemented by evaluation of gr...
