Aminoácidos de cadeia ramificada na alimentação de suínos: Revisão

Protein is the component that most interferes with animal growth, influencing parameters such as weight gain, daily feed intake and feed conversion ratio. This organic component consists of polymerized units of amino acids, which are classified as essential and non-essential amino acids. The branched-chain amino acids (leucine, valine and isoleucine) are part of the group of essential amino acids characterized by their branched chain structure, they are oxidized as fuel mainly by the muscular, adipose, renal and encephalic tissues, having the ability to directly influence the synthesis of protein, in addition to having a synergistic effect with insulin to stimulate the uptake of glucose by the cells. These characteristics are of interest to nutritionists who aim to optimize diets for pigs that meet the nutritional requirements of animals, improving production parameters and avoiding excess ingredients in diets to reduce environmental pollution. The objective of this review is to facilitate the knowledge and importance of branched chain amino acids in nutrition pigs.
