Three experiments were conducted to examine the effects of injectable trace minerals (ITM) on measures of trace mineral status and performance in pre- and postweaned Brangus-crossbred beef calves. In Exp. 1, calves were assigned to treatments in alternating birth order (n = 150; 75/treatment), consisting of a 1-mL subcutaneous injection of ITM (MultiMin 90; MultiMin USA, Inc., Fort Collins, CO)...

Trace element levels are associated with the incidence of osteoporotic fractures, but related mechanisms remain unknown. Trace elements may interfere with growth, development and maintenance of bones. Therefore, we investigated whether plasma trace element levels are associated with bone mineral density in elderly males in Beijing. After epidemiologically investigating 91 elderly males with age...

An abundance of trace metals in the environment is a characteristic property of only a few terrestrial ecosystems. Serpentinite contains high concentrations of trace metals especially Ni and Cr that are released by weathering. Other natural sources of trace metals are volcanic eruptions and the deposition of marine aerosols. In the soil some trace metals are strongly adsorbed to the mineral mat...

The present study was performed in order to evaluate the effects of lower than usual industry levels of dietary trace minerals on plasma levels, faecal excretion, performance, mortality and morbidity in growing-finishing pigs in a hot African climate. Group 1 (n = 100 pigs) received a diet with common industry levels of trace minerals. Group 2 (n = 100 pigs) received reduced dietary trace miner...

This study was aimed at investigating the hematological, biochemical and trace mineral status of cattle with foreign body rumen impaction. Hematological, serum biochemical and trace mineral parameters of cattle with Foreign Body Rumen impaction (FBR) and normal cattle Without Foreign Body Rumen impaction (WFBR) were analyzed in order to evaluate their influence as risk factors in the etio-patho...

Three experiments were conducted to determine the effects of omitting vitamin and trace mineral premixes and(or) reducing inorganic phosphorus additions to finishing diets on growth performance, carcass characteristics, and muscle quality in pigs. In Exp. 1, a corn-soybean meal-based diet (.70% lysine, .65% Ca, and .55% P) was used as the control. Pigs (n = 128; average initial BW of 85.7 kg) w...

OBJECTIVE To investigate fetal exposure to toxic metals [lead (Pb), cadmium (Cd)] and fetal levels of trace elements [zinc (Zn), copper (Cu), and iron (Fe)] in newborns from an industrial city. Relationships between meconium mineral contents and parental occupation and location of residence were also tested. METHOD The meconium mineral contents of 117 healthy newborn infants were measured by ...
