In a new paper, a team of evolutionary biologists and geneticists led by Ana Caicedo and Hamid Razifard of the University of Massachusetts Amherst report that they have identified missing li...
Three hundred and seventy-three steers (approximately 7 mo of age and 24719.4 kg) were utilized to determine the effects of trace mineral (TM) source and growth implants on trace mineral statu...
This study was conducted to determine the effects of feeding a trace minerals-fortified microbial culture (TMC) on the performance and carcass characteristics of late-fattening Hanwoo steers. A mixtur...
We examined whether it is possible to relate concentrations of trace elements in alluvial sediments with records concerning the intensity of mining, and use them as a means of dating. We conducted our...
Four sequential extraction procedures (Sposito, Tessier, Silveira and Bureau Communautaire de Reference (BCR)) were used to evaluate the distribution of some metals (Fe, Cu, Cd and Zn) in a contaminat...
Mastitis is a highly morbid disease that requires detection at the subclinical stage. Tropical countries like India mainly depend on milch buffaloes for milk. The present study was conducted to invest...
The objective of this study was to examine the effects of concentrates containing different levels of a vitamin-trace elements premix on milk yield and composition of dairy cows. The trial, which last...
Trace minerals such as zinc, copper, and manganese are essential cofactors for hundreds of cellular enzymes and transcription factors in all animal species, and thus participate in a wide variety of b...
An experiment was conducted to study the effect of microbial phytase on excretory phosphorus (P), copper (Cu), zinc (Zn) and manganese (Mn) in broiler chicks. Male broiler chicks with three replicatio...
The main sources of trace metals to plants are the air or soil media from which trace elements are taken up by the root or foliage. The air, soil and vegetable samples were collected from Industrial,...
Bromide (Br-) was used to successfully trace the infiltration of rainfall through a sandy soil in northeast Thailand. A method was developed to measure the Br- concentration in extracted water from so...
Metal (Cd, Cr, Cu, Hg, Ni, Pb and Zn) and metalloid (As) status of two urban farms in Ethiopia were determined using the European Community Bureau of Reference (BCR) modified sequential extraction m...
In this pot experiment, poultry manure dried by Fan separator was applied at different rates N to see the effect of poul-try manure on the growth and total N uptake of corn and rice. Contribitions of...
spraying of iron, zinc and manganese as each alone at 50 or 100 ppm or in triple combination of them at 50 ppm for each on plant grown under sandy soil conditions resulted in significant enhancement...
Trace metal contents in zooplankton samples were estimated as a part of Marine Research- Living Resource Programme (MRLR) programme at 24 stations to establish the importance of these metals in the ...
