Trace Mineral Requirements for Dairy Cattle
A host of nutrients are needed by cattle to support functions associated with life, and to grow, reproduce, and nourish their offspring (i.e., produce milk). A vast amount of resources have been expended to quantify the amounts of specific nutrients needed to perform these function so that economically efficient diets can be formulated. Feeding diets that provide adequate, but not excessive, am...

متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Vitamin D Metabolism in Dairy Cattle and Implications for Dietary Requirements
Vitamin D was originally discovered nearly a century ago as a factor in butterfat that prevented rickets (McCollum et al., 1922). In the years to follow it was also found to be synthesized in the skin exposed to sunlight and to be critically involved in calcium homeostasis. The role of vitamin D in calcium homeostasis initiated research on its use for milk fever prevention in dairy cattle, and ...
