Two experiments were conducted to determine the effects of increasing the dietary Zn content on growth performance, carcass characteristics, plasma Zn, and ileal mucosal inflammation mRNA expression of finishing pigs fed diets containing ractopamine HCl (RAC; Elanco Animal Health, Greenfield, IN). In Exp. 1, 312 pigs (327 × 1050; PIC, Hendersonville, TN; 94 kg BW) were used in a 27-d study. The...

The effects of high Zn concentration were investigated in sugar beet (Beta vulgaris L.) plants grown in a controlled environment in hydroponics. High concentrations of Zn sulphate in the nutrient solution (50, 100 and 300 microm) decreased root and shoot fresh and dry mass, and increased root/shoot ratios, when compared to control conditions (1.2 microm Zn). Plants grown with excess Zn had inwa...

in order to study the influence of municipal waste compost and chemical fertilizer on yield and yield components in maize (zea mays l.) an experiment was conducted at research farm of sari agricultural sciences and natural resources university during 2007. the experiment was arranged in split plots based on complete randomized block design with two factors and three replications. main plot incl...

I . Male hooded Lister rats given a diet containing 40 mg zinc/kg were described as Znadequate. Other rats were subsequently given diets containing less than I m g Zn/kg. After a period of approximately 5 d these animals ceased to grow and were described as Zn-deficient. 2. Zn-deficient rats offered ad lib. a Zn-deficient diet containing 200 g egg albumenjkg ate only 55 "/o of the weight eaten ...

Cadmium can be found in wastewater in high concentrations and can cause dangerous effect on aqueous environment and human health. At present, many methods have been used to heavy metals removal. Among this clean up techniques, adsorption techniques by using low-cost adsorbent are more considerable. In this study, batch adsorption experiments were conducted for removal of cadmium ions from a...

Particulate matter accumulated on tree bark specimens was examined in order to investigate its potential use as a natural monitor to study the impact on local atmospheric conditions. Tree bark from sargent cherry (Prunus sargentii) and sugar maple (Acer saccharum Marsh) trees was collected from four locations: Drax (North Yorkshire), Darley Dale (Derbyshire), Galway (Ireland) and Tristan da Cun...

In this study, Zn-doped calcium silicate (Zn-WO) materials were successfully synthesized. As precursors, Ca (OH)2, SiO2, and ZnO utilized, then the hydrothermal experiment was conducted for 6 hours at 1050°C. work, behavior of two groups raw exposed to isobaric different temperature circumstances is described. The synthesized sample examined using XRD, SEM, EDAX, Raman, BET, UV-Vis spectroscopi...
