Zinc (Zn) as a micro mineral is essential for growth, skeletal development, and immune competence in chickens (Hudson et al., 2004). Inorganic Zn salts, such as sulphate and oxide, are generally supplemented in diets to meet the Zn requirement of chickens (Cao et al., 2002). However, in the recent past Inorganic trace minerals (ITMs) have been replaced by organic trace minerals (OTMs) because o...

background: increased requirement and decreased dietary intakes of micronutrients during pregnancy might affect maternal health and pregnancy outcomes. this study was aimed to examine the effects of two types of multiple micronutrient supplementations on pregnancy outcomes in kashan, iran. methods: in a randomized single‑blind controlled clinical trial, 104 primigravid singleton pregnant women ...

The management of coal ash in utility boilers continues to be one of the most important fuel property considerations in the design and operation of commercial boilers. The behavior of mineral matter in coal can significantly influence furnace sizing, heat transfer surface placement, and convection pass tube spacing. Ironically, many of the more reactive, low rank U. S. coals must have larger fu...

The trend in the industry T H E MINERAL-PROCESSING INDUSTRY is , and will remain, very sensitive to the metal market, which in turn is very dependent on the use of metals for the improvement of lifestyle in developing and developed countries. An assumption is made that the weapons industry will have a reduced effect in the future on the use of metals, and therefore on prices. The cost of metal ...

OBJECTIVE An experiment was conducted to evaluate dietary supplemental trace mineral source and deletion on mineral content in tissues. METHODS Weanling crossbred pigs (n = 144; 72 barrows and 72 gilts; body weight [BW] = 7.4±1.05 kg) were used. A basal diet was prepared, and trace mineral premix containing either inorganic (ITM) or organic (OTM) trace minerals (Cu, Fe, Mn, and Zn) was added ...

A cooperative study comprising growth performance, bone mineralization, and nutrient balance experiments was conducted at 11 stations to determine the standardized total-tract digestible (STTD) P requirement of 20-kg pigs using broken-line regression analysis. Monocalcium phosphate and limestone were added to a corn-soybean meal-based diet at the expense of cornstarch to establish 6 concentrati...

Iron ore concentrate sales in a mineral processing plant appeared a trend of high sulfur, exceeding the sales requirement of 0.3% significantly. To this end, for the sulfide in iron concentrate mainly exists in the form of pyrrhotite, companies with iron minerals and has a high degree of oxidation, we can add flotation agent to the magnetic separation column, and at the same time fill gas for s...

Edited by two leading paediatric endocrinology experts from UK, the second edition of this book is a one stop exhaustive compendium of updated information related to bone and mineral physiology and related disorders in children and adolescents. This field has witnessed a rapid gain in information during the last decade, which should now translate it into better clinical practice. This multi-aut...
