The microbial immobilization of zinc sulfate
Microbial immobilization of soluble zinc (ZnSO<sub>4</sub> ) as ZnS was investigated to reduce the possible hazardous effects of soluble Zn in aquatic systems. Static three-phase microcosms were designed to simulate certain characteristics of natural systems in the laboratory. Microcosms (40, 15, …

Zinkserumresponse beim Pferd nach oraler Verabreichung von unterschiedlichen Zinkverbindungen
Summary In the here presented study, the zinc serum response was investigated after the application of 4 different zinc compounds with varying dosages. To be able to consider species differences, dogs and cats were also supplemented with the same compounds and the zinc serum values measured. A …

Detecting Giardia: Clinical and Molecular Identification
… on direct fecal smears or cysts on centrifugal zinc sulfate fecal flotations), and it is currently recommended to use morphologic techniques in conjunction with a sensitive and specific antigen test. Diagnosis is important for management of clinical giardiasis in cats and dogs and also to …

Supplementing Bovine Embryo Culture Media to Improve the Production and Quality of In Vitro Produced Bovine Embryos
… Additionally, we assessed the suitability of zinc sulfate and a bovine embryonic stem cell culture media (TeSR) for improving bovine embryo development in vitro. Zinc sulfate increased day 8 blastocyst total and ICM cell number. Therefore, zinc sulfate appears to improve blastocyst quality. …

Abscheidung von Nickel und anderen Schwermetallen bei der Reinigung von Zinksulfatlösungen durch Zementieren mit Zinkstaub
The industrial production of zinc sulfate employs aqueous ZnSO4 solutions. These are made from leaching zinc-containing secondary materials with sulfuric acid, with the result that they are contaminated with considerable quantities of heavy metals. These metals are removed from the solution by the …

Evaluation of modified montmorillonites in poultry diets
… available than Cu from Mintrex®Cu and copper sulfate. Serbia Zn-MONT and Zn-IMTX ameliorated the growth depressing effects of AF, and Zn-IMTX also reduced the negative effects of AF on liver weights. Results suggest that birds supplemented with Zn-IMTX were better protected against the toxic …

Feline Parasitism: Parasite Prevalence and Evaluation of New Immunoassays for Giardia and Cryptosporidium
… In addition, samples were examined using a 33% zinc sulfate (ZnSO4) centrifugal fecal flotation procedure and the MERIFLUOR® Cryptosporidium/Giardia direct immunofluorescent assay (IFA), which served as the reference test. Other internal parasites found on the centrifugal fecal flotation with …

Controlled Release of Insulin and Modified Insulin from a Novel Injectable Biodegradable Gel
… water-soluble and water- <br />insoluble zinc salts on blood glucose lowering effect of insulin in type-2 diabetic ZDF rats was investigated. Insulin formulations containing varying concentrations of different water-soluble and water-insoluble zinc salts were prepared and injected …

The production of a plastic form sulfate lignin
… the best quantity to use. A run was made using zinc sulfate treated lignin instead of stannous lignin. The zinc sulfate treated lignin when condensed with furfural had a lower per cent of water absorption than the stannous lignin when condensed with furfural. This low water absorption value was …

Zinc in potato production
Zinc deficiencies have been reported from the states of Washington, Idaho, North Dakota and Texas. The deficiencies are reported to be localized in areas where the parent material of soil is low in zinc content or where the topsoil has been removed by landleveling or lost through erosion. There is …

Electrode reactions in zinc electrolysis
… current efficiency in the electrolysis of pure zinc sulfate solutions (65 gpl Zn⁺⁺ - 200 gpl H₂SO₄) were determined. Pure platinum and platinum coated titanium anodes were used with an aluminum cathode. Platinum anodes were not inert at certain combinations of temperature and current density, …

The effects of zinc intake and exercise on iron status of pregnant Sprague-Dawley rats
The effects of marginal zinc intake and exercise on the iron status of Sprague-Dawley rats during pregnancy were observed. The dams were assigned to one of four groups: zinc marginal (6.18 ppm zinc sulfate), exercise or sedentary; zinc adequate (37.63 ppm), exercise or sedentary. The dams swam …
