SOURCES OF MINERALS FOR HENS

Abstract

Optimizing your metabolism and maximizing the performance of the birds are dependent upon adequate nutrition. Approximately 50 substances are needed for the normal functioning of the body, but part of these substances can not be synthesized or are synthesized in insufficient quantities for the perfect functioning of metabolic birds. Among these substances, which are called essential nutrients, are minerals. The minerals are divided into macro-minerals, which must be supplied in large quantities and micro-minerals, which are required in small quantities in the body. The micro-mineral, also known as trace minerals, act as components of protein structures or as co-factors, assisting in the amendment or alostérica modulation of the tertiary structure of enzymes, making them active or inactive. For many years, nutritionists have used as inorganic minerals (example: zinc sulfate, sodium selenite, copper sulfate and another). Minerals to meet the requirements of the birds. To achieve the gastrointestinal tract minerals must be solubilized initially for liberarem ions and be absorbed. However, being in the form ionic minerals can complexar with other components of the diet, hindering the absorption or, if fully complexed, making them unavailable to animals. In view of these uncertainties, the levels of minerals supplied in the diet are often higher than the minimum required for optimum performance, resulting in over-supply. Currently, there is a greater interest in being supplied mineral or organic sources kelatiranih of trace minerals, often described as proteinates.
