Concentração de minerais na palma forrageira e suas implicações no metabolismo de ruminantes: revisão de literatura

Abstract

The forage palm is used in the feeding of ruminant animals, mainly in the regions that have low rainfall indexes, because it presents great adaptability to more arid climates and presents great amount of water in its composition, contributing significantly to the watering of the animals. However, this forage has other characteristics such as imbalance of minerals (Ca: P, for example), high concentrations of calcium (Ca), potassium (K) and magnesium (Mg) and low concentrations of phosphorus (P) and sodium (Na) that signal the need for care in the mineralization of the herd. These imbalances can lead to problems in productive performance, reproductive health and health of ruminant animals that consume this fodder resource. Given the importance of knowledge of the mineral composition of foods to formulate suitable diets for ruminant animals the objective was to carry out a bibliographical survey on the role of minerals in ruminant feeding and the concentration of these in the forage palm.
