The water-soluble zinc salts gluconate, sulfate, and acetate are commonly used as supplements in tablet or syrup form to prevent zinc deficiency and to treat diarrhea in children in combination with oral rehydration. Zinc citrate is an alternative compound with high zinc content, slightly soluble in water, which has better sensory properties in syrups but no absorption data in humans.We used th...

The aim of this study was to determine effect of in ovo injection of nanoparticles of zinc oxide on hatching, growth performance and carcass yield of broiler chicks after hatching. In total, 324 fresh hatching eggs were randomly distributed into six treatment groups of 54 eggs per treatment with three replicates of 18 eggs each, and injections were performed on day 15 of incubation. The treatme...

Despite its superior characteristics, there is an increased concern about the environmental effects that zinc oxide causes and over the years lower levels of zinc have been tried in order to decrease its impact and to minimise the production costs. Different approaches have been considered for reducing zinc levels. Between all the alternatives proposed, the use of nano–sized ZnO particles with ...

Background : One of the major disadvantages of zinc oxide in aqueous solution is the light unstability of this catalyst due to the light corrosion which causes substantial reduction of photocatalytic activity of zinc oxide and application of it for environment purification. In this study, the performance of photocatalytic of UV/Silica-ZnO was compared in dye and COD removal by UV/ZnO. Materials...

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...

Background and Objectives: Water pollution with oil compounds causes the development of new technologies to eliminate oil pollution. The purpose of this study was to determine the efficiency of synthesized zinc oxide nanoparticles in the adsorption of oil from aqueous media. Materials and Methods: In this laboratory study performed in the summer of 2019, zinc oxide nanoparticles were used as a...
