Resposta individual de suínos a níveis crescentes de valina e isoleucina

Abstract

The constant search of increasing understanding of the nutritional requirements of pigs allowed numerous advances in the determination of nutritional requirements and formulating diets that precisely meet the needs of the animals, reducing costs to the producer, increasing the percentage of lean meat and causing less damage to the environment. A better knowledge of individual nutritional requirements allows a nutrition more precise, allowing the nutritionist a formulation with lower crude protein and higher amounts of industrialist amino acid. However, despite the knowledge of some amino acids such as lysine and methionine, little is known about the individual requirement of valine and isoleucine for pigs, more research is necessary with these amino acids. This way, this stage was aimed at tracking a test dose response with increasing levels of valine and isoleucine for growing pigs. The stage course conclusion was held at the Faculdade de Ciências Agrárias e Veterinárias (FCAV), Universidade Estadual Paulista "Júlio de Mesquita Filho", located in Jaboticabal, São Paulo, in the period from August 4 to November 3, 2014. Academic activities were developed such as: literature review, feed formulation and monitoring of experiments, having as main objective the conduct of this study. Determining the individual requirement of valine and isoleucine for pigs is essential for the precision nutrition, since in this way it is possible a significant reduction in potentially polluting crude protein content of the diets and, consequently, reduce costs and potentially polluting elements. Tracking a test dose response with increasing levels of amino acids was crucial for this study course conclusion. New methodologies, techniques and concepts been observed, providing professional growth size in nutrition of monogastric.
