This research was conducted to evaluate immunity (experiments 1 to 3), cardiac function, and ascities resistance (experiment 4) of progeny chicks from broiler breeders fed diets differing in trace metal level and source. Broiler breeders received a control diet (75 mg of Zn and 83 mg of Mn added/kg of diet), the control diet supplemented with inorganic Zn (75 mg/kg of diet) and Mn (80 mg/kg of ...

The effects of selected metals (Mg, Mn, Zn, and Fe) on 3-acetyldeoxynivalenol (3-ADN) production by Fusarium graminearum R2118 and on its mycelial growth were investigated by using a two-stage submerged-culture technique. In certain concentrations ranges, Mg and Fe stimulated growth but suppressed 3-ADN production; at other concentrations, Mg, Fe, and Zn suppressed growth but stimulated 3-ADN p...

OBJECTIVES The objectives of this study were to evaluate manganese (Mn)-containing welding fumes' exposure, assess urinary Mn as a biomarker for Mn exposure and investigate the correlation of Mn in air, total fumes and urinary Mn with pulmonary function indices in 118 welders and 37 unexposed controls from two regions in Iran, Assaluyeh and Borujen. METHODS Air samples were collected on mixed...

The nervous system is the major target of the toxic effect of manganese (Mn) and its compounds. Nowadays, neurological diagnostics is directed towards early detection of symptoms and abortive forms, and the cases of serious damage of the nervous system are no longer reported. The aim of the present study was to assess the effects of manganese on the functions of the nervous system in workers ex...

Thirteen isolates of Cladobotryum spp., isolated from diseased fruiting bodies of Agaricus bisporus, sampled from mushroom farms in Serbia during 2003-2006, were studied. Sensitivity to several selected fungicides was tested and all isolates were found to be highly sensitive to iprodione (EC50 = 0.35-2.30 mg L-1), benomyl (EC50 = 0.14-0.97 mg L-1) and especially to prochloraz-Mn (EC50 = 0.02-0....

Graded levels of a trace mineral premix containing an organic (Bioplex) source of Cu, Fe, Mn, and Zn was evaluated with additional treatments containing organic Zn or Fe. Grower-finisher pigs were fed from 25 to 115 kg BW. The number of pigs in the experiment, the breeding/genetics of the pigs, the management, and the average age of the pigs were previously reported. The experiment was conducte...

Sugar maple and red maple are closely-related co-occurring tree species significant to the North American forest biome. Plant abiotic stress effects including nutritional imbalance and manganese (Mn) toxicity are well documented within this system, and are implicated in enhanced susceptibility to biotic stresses such as insect attack. Both tree species are known to overaccumulate foliar mangane...
