Trace Elements In Human Diet And Animal

Minerals needed for normal functioning of animals and humans, are usually divided into two groups: macronutrients and micronutrients. By macro-usually referred calcium, magnesium, phosphorus, potassium, chlorine and sulfur. K trace elements – chromium, cobalt, copper, iodine, iron, manganese, molybdenum, nickel, selenium and zinc. For some species are also important in arsenic, boron, lead, silicon and vanadium. For people in the recommended dosage is established minimum amount sufficient to prevent deficiency of each component.

For animals, this dosage is established based on maintaining peak performance. In recent years, there were many recommendations for improving the nutritional assessment of feed and animal feed regulation. In our country adopted a comprehensive assessment of nutrient feed, which includes their energy value. The development of norms energy and vitamin nutrition of animals allows the veterinarian specialists make science-based diet, taking into account the chemical composition of feed used. In this article we elaborate on micronutrients. Iron.

Iron – antianemichesky mineral, is a molecule of hemoglobin, participates in the oxygenation of the cells, digested only in the presence of vitamins C and E, gives the skin a pink color. In humans, contains 5 grams of iron. 70% of this amount accounted for by hemoglobin, a part of it is contained in muscles (myoglobin), redox enzymes (peroxidases, cytochromes, etc.). Iron deficiency can develop because of its scarcity in food (in infants contained on artificial feeding, complementary feeding with untimely against the background of breastfeeding, since breast milk iron is not supplied). Iron deficiency occurs when there is a diet of large amounts of inorganic phosphorus with which it forms a poorly soluble compounds, or inflammatory processes in the intestine, which are combined with ferritinovogo violation mechanism.
