Abstract

The aim of this project is to study the problem of variability in response of animals at establish levels of methionine in the diet of growing pigs. This study is part of a larger project about integrated systems for precision nutrition for pigs (JP Project No. 2012/03781-0). To cater this goal, the project was divided into two studies. The first proposes to study, through meta-analysis, the types and levels of methionine and lysine: methionine ratio conventionally used in pig populations for further study of the model. The systematization of data and application of statistical techniques allow an overview of the population response to different ingestions of methionine. Providing a greater foundation for application and validation of the prediction model of nutritional requirements. In the second study, proposes to study the animal response to ingestion of diets with different levels of methionine provided by "Automatic and Intelligent Precision Feeder" (AIPF) using the model proposed by Hauschild et al., (2012). This model considers the animal variability, which directly impacts the reduction of production costs, the lower excretion of nitrogen and phosphorus to the environment and a likely improvement in the welfare and health of these animals. If successful this project will allow the implementation of a new system for estimating nutrient requirements and a new method of feeding pigs providing considerable advances in the area of nutrition and precision for Brazilian pig production.
